Flora of Espírito Santo: Commelinaceae

Abstract

This work is a part of the Flora do Espírito Santo project. The aim was to morphologically characterize the species of Commelinaceae occurring in the state of Espírito Santo and provide data on their geographical distribution, phenology, and comments. Fieldwork and herbarium studies were carried out. A total of 38 species, arranged in 10 genera, were recorded. Dichorisandra is the richest genus (17 species), followed by Commelina (seven spp.), Tradescantia (four spp.), Siderasis (three spp.), Tripogandra (two spp.), and Aneilema, Callisia, Floscopa, Gibasis and Tinantia (one species each). Two species are herein described as new to science, and the synonymization of D. albomarginata is proposed under the older D. procera. Inflorescence (type and position), stamens (number, color, and anther dehiscence), fruit (shape and ornamentation), and seeds (ornamentation, the position of the embryotega, and hilum shape) are the key diagnostic morphological characters for genus and species delimitation. Most of the species richness and abundance are concentrated in the mountain region of Espírito Santo, one of the largest forest areas in the state, showing the importance of conserving the remaining Atlantic Forest’s fragments.

Resumo

O presente trabalho é parte integrante do projeto Flora do Espírito Santo. O objetivo foi caracterizar morfologicamente as espécies de Commelinaceae ocorrentes no estado do Espírito Santo e fornecer dados sobre sua distribuição geográfica, fenologia e comentários. Expedições de coleta e análises de material de herbário foram realizados, buscando inventariar as espécies ocorrentes no estado. Um total de 38 espécies em 10 gêneros foram registradas, sendo Dichorisandra o gênero mais representativo em números de espécies (17 spp.), seguido por Commelina (sete spp.), Tradescantia (quatro spp.), Siderasis (três spp.), Tripogandra (duas spp.) e Aneilema, Callisia, Floscopa, Gibasis e Tinantia (uma sp. cada). Duas espécies são aqui descritas como novas para a ciência e, a sinonimização de D. albomarginata sob D. procera é proposto. Caracteres morfológicos como: inflorescência (tipo e posição), estames (número, cor e deiscência), fruto (forma e ornamentação) e sementes (ornamentação, posição da embrioteca, e forma do hilo) são os principais caracteres diagnósticos para delimitação de gênero e espécie. A maior riqueza e abundância das espécies concentra-se na região serrana do Espírito Santo, uma das maiores áreas florestais do estado, evidenciando a importância da conservação e preservação dos fragmentos remanescentes de Mata Atlântica.

Introduction

Commelinaceae comprises 41 genera and 720 species (Govaerts & Faden 2011Govaerts R & Faden RB (2011) World checklist of Commelinaceae. The board of trustees of the Royal Botanic Gardens, Kew. Available on <http://apps.kew.org/wcsp/home.do>. Access on 28 November 2018.

), divided into two subfamilies: Cartonematoideae with only two genera, the Australian Cartonema with 11 species, and the monospecific Triceratella from South Africa; and Commelinoideae, with 39 genera and the remaining species, being Pantropical (Faden & Hunt 1991Faden RB & Hunt DR (1991) The classification of the Commelinaceae. Taxon 40: 19-31.). Commelina (230 species) is the most diverse genus, followed by Tradescantia (90 species), Aneilema (65 species), and Dichorisandra (63 species) (Hardy & Faden 2004Hardy CR & Faden RB (2004) Commelinaceae.

Pp. 425-427.; Aona 2008Aona LYS (2008) Revisão taxonômica e análise cladística do gênero Dichorisandra J.C.Mikan (Commelinaceae). Ph.D. thesis.

(Commelinaceae) sheds light on a new infrageneric classification for the genus and novelties on the systematics of subtribe Tradescantiinae. PhytoKeys 89: 11-72., 2019).

The family presents considerable morphological variation, especially regarding its inflorescences, flowers, and seeds (Faden 1998Faden RB (1998) Commelinaceae. In: Kubitzki K (ed.) The families and genera of vascular plants. Vol. 4. Springer Verlag, Berlin. Pp. 109-128. <https://doi.org/10.1007/978-3-662-03531-3_12>). This wide variation makes morphological characters relatively tricky to interpret and has led to many taxonomic and systematic issues (Evans et al. 2003Evans TM, Sytsma KJ, Faden RB & Givnish TJ (2003) Phylogenetic relationships in the Commelinaceae: II. A cladistic analysis of rbcL sequences and morphology. Systematic Botany 28: 270-292.; Pellegrini 2019). Characters such as habit, inflorescence architecture, the number, color and ornamentation of stamens, anther dehiscence, and fruit and seed morphology are some of the most taxonomically relevant characters in the family (Pellegrini 2019).

Studies in the family, especially addressing the morphology and delimitation of genera and species, are still very scarce (Pellegrini 2017bPellegrini MOO (2017b) Morphological phylogeny of Tradescantia L. (Commelinaceae) sheds light on a new infrageneric classification for the genus and novelties on the systematics of subtribe Tradescantiinae. PhytoKeys 89: 11-72., 2019). In Brazil, only a handful of studies have been published for Commelinaceae: 1) floristic studies (Barreto 1997Barreto RC (1997) Levantamento das espécies de Commelinaceae R.Br. nativas do Brasil.

In Brazil, 116 taxa are recorded, of which 59 are endemic. The Atlantic Forest domain has the highest number of species (80 spp.), followed by the Cerrado (37 spp.), the Caatinga (31 spp.), the Amazon Forest (30 spp.), and the Pampa and Pantanal (16 spp., each) (Aona et al. 2020Aona LYS, Pellegrini MOO & Amaral MCE (2020) Commelinaceae in Flora do Brasil 2020.

) have recorded 33 species arranged in ten genera for the state of Espírito Santo. Of the recorded genera, Dichorisandra is the most diverse in the state (13 spp.), followed by Commelina (six spp.) and Tradescantia (three spp.) (Dutra et al. 2015Dutra VF, Alves-Araújo A & Carrijo TT (2015) Angiosperm checklist of Espírito Santo: using electronic tools to improve the knowledge of an Atlantic Forest biodiversity hotspot.

).

As part of the Flora do Espírito Santo project, we provide a floristic treatment for Commelinaceae in the state of Espírito Santo, aiming to clarify the number, identity and delimitation of accepted taxa. We present descriptions, identification keys, comments, phenological information, distribution maps, and illustrations for all taxa.

Material and Methods

This study was based on fieldwork and analysis of material from the following herbaria: ALCB, BHCB, CEPEC, CESJ, CVRD, ESA, FLOR, HB, HRCB, HUEFS, HUEM, HURB, MBM, MBML, MO, NY, P, R, RB, RBR, RFA, SAMES, SP, SPF, SPSF, U, UEC, UPCB, US, VIC, and VIES (acronyms according to Thiers, continuously updated). Field expeditions were carried out mainly at localities with previous records gathered from the visited herbaria and online databases (CRIA 2020CRIA (2018) SpeciesLink Ferramenta desenvolvida pelo CRIA. Available at <http://www.splink.org.br>. Access on 28 November 2018.

). Samples were collected and dried according to the usual taxonomic procedures (Mori et al. 2011Mori SA, Berkov A, Gracie CA & Hecklau EF (2011) Tropical plant collecting. From the Field to the Internet. TECC Editora, Florianópolis. 332p.). Vouchers were incorporated at VIES herbarium, and duplicates were sent to RB and US.

For species identification, samples were compared to type specimens, protologues, and specialized literature (e.g., Aona 2008Aona LYS (2008) Revisão taxonômica e análise cladística do gênero Dichorisandra J.C.Mikan (Commelinaceae).

(Commelinaceae) in the state of Rio de Janeiro, reveals a new white-flowered species endemic to Brazil. PhytoKeys 78: 59-81.). Only native and naturalized species were included in the present study, thus, excluding species with no proof of having escaped cultivation. Sterile specimens were collected and kept under cultivation at the Universidade Federal do Espírito Santo (UFES), aiming to photograph and analyze fresh flowers, fruits, and seeds.

The richness analyzes and species records were done using the Circular Neighborhood Method (CNM), facilitated by the DIVA-GIS 7.5.0 software (Hijmans et al. 2012Hijmans RJ, Guarino L & Mathur P (2012) DIVA-GIS. Version 7.5.0. A geographic information system for the analysis of species distribution data. Available at <http://www.diva-gis.org>. Access on 8 January 2019.

). For the distribution maps, Quantum-GIS software version 2.12 was used.

Results and Discussion

A total of 38 taxa arranged in 10 genera are accepted by us for the state of Espírito Santo, including native (37) and naturalized (one) species. Two species, Dichorisandra aonae and D. glandulosa, are herein described as new to science. A third species, Dichorisandra sp., most likely represents a new species but will be described in a posterior study.

Alternatively, Tradescantia zebrina hort. ex Bosse (1849: 655)Bosse J (1849) Tradescantia zebrina hort. ex Bosse. Vollständiges Handbuch der Blumengärtnerei 4: 655.is broadly recognized as an aggressive invasive, being commonly found in Espírito Santo in anthropized areas.

Sumtibus Auctoris, Typis Antonii Strauss, Viena. 23p., and Siderasis fuscata (Lodd.) Moore (1956: 28)Moore HE (1956) Siderasis fuscata (Lodd.) H.E.Moore. Baileya 4: 28. were recorded for the state by Dutra et al. (2015)Dutra VF, Alves-Araújo A & Carrijo TT (2015) Angiosperm checklist of Espírito Santo: using electronic tools to improve the knowledge of an Atlantic Forest biodiversity hotspot. Rodriguésia 66: 1145-1152.. Nonetheless, these species’ occurrence was not confirmed and were misidentifications. Samples determined as Commelina villosa, Dichorisandra glaziovii, and D. perforans respectively correspond to C. benghalensis Linnaeus (1753: 41)Linnaeus C (1753) Commelina benghalensis L. Species Plantarum 1: 41. , D. striatula Moraes & Pellegrini (2019: 783), and D. penduliflora Kunth (1843: 114)Kunth CS (1843) Dichorisandra penduliflora Kunth. Enumeratio Plantarum Omnium Hucusque Cognitarum 4: 114.. Furthermore, D. thyrsiflora is often used to identify several Espírito Santo collections. Those samples correspond to D. procera Martius ex Schultes f. (1830: 1187)Schultes F (1830) Dichorisandra procera Mart. ex Schult. f. Systema Vegetabilium 7: 1187-1188., which is morphologically similar but can be distinguished by its poricidal anthers with two apical pores (vs. one in D. thyrsiflora). Siderasis fuscata, which is endemic to the state of Rio de Janeiro, was erroneously used to identify specimens of S. albofasciata (Pellegrini 2017aPellegrini MOO (2017a) Siderasis albofasciata sp. nov. (Commelinaceae), endemic to the state of Espírito Santo, Brazil, and the typification of S. fuscata. Nordic Journal of Botany 35: 29-37. <https://doi.org/10.1111/njb.01267>.; Pellegrini & Faden 2017Pellegrini MOO & Faden RB (2017) Recircumscription and taxonomic revision of Siderasis, with comments on the systematics of subtribe Dichorisandrinae (Commelinaceae). PhytoKeys 83: 1-41.).

Dichorisandra is the richest genus with 17 species, followed by Commelina (seven spp.), Tradescantia (four spp.), Siderasis (three spp.), Tripogandra (two, spp.), and Aneilema, Callisia, Floscopa, Gibasis, and Tinantia with one species each. In terms of species’ number and records, the Central (mainly Linhares and Colatina municipalities) and Metropolitan macroregions (Santa Teresa) (IBGE 2017IBGE - Instituto Brasileiro de Geografia e Estatística (2017) Divisão Regional do Brasil em Regiões Geográficas Imediatas e Regiões Geográficas Intermediárias 2017. IBGE, Coordenação de Geografia, Rio de Janeiro. 82p.) of Espírito Santo are the richest areas which show a higher number of species and the greatest number of records of Commelinaceae (Fig. 1). These macroregions include different vegetation types such as seasonally dry forests and rainforests (Garbin et al. 2017Garbin ML, Saiter FZ, Carrijo TT & Peixoto AL (2017) Breve histórico e classificação da vegetação capixaba. Rodriguésia 68: 1883-1894.), explaining the abundance of Commelinaceae. Most Neotropical Commelinaceae species are associated with humid and shaded environments, growing mainly in rainforests and remnants of seasonally dry forests associated with inselbergs (Hardy & Faden 2004Hardy CR & Faden RB (2004) Commelinaceae. In: Smith N, Mori SA, Henderson A, Stevenson DW & Held SV (eds.) Flowering plants of the neotropics. Princeton University Press, Princeton. Pp. 425-427.; Barreto 2005Barreto RC (2005) Commelinaceae.

(Commelinaceae) in the state of Rio de Janeiro, reveals a new white-flowered species endemic to Brazil. PhytoKeys 78: 59-81.). Moreover, our results indicate that this large number of records to be associated with focused and intense collection efforts in the largest forested areas in Espírito Santo (Fig. 2), in addition, other studies in the state as Murray-Smith et al.

Taxonomic treatment

Commelinaceae Mirb., Hist. Nat. Pl. 8: 177. 1804.

Herbs annual or perennial, usually succulent, terrestrial, rupicolous, aquatic, rarely epiphytes. Roots fibrous or tuberous. Stems ascending, erect or prostrate, sometimes decumbent, vining or scrambling. Leaves alternate, distichously or spirally-alternate, sessile or pseudopetiolate; sheaths closed, veins parallel. Inflorescences thyrsoid, sessile or pedunculate; basal bract tubular, bracteose, leaf-like or spathaceous; main axis developed or not; cincinni 1-many, free or fused back to back, alternate, subopposite, verticillate or fasciculate; cincinnus bract absent, bracteose, leaf-like or spathaceous. Flowers actinomorphic, zygomorphic or asymmetric (enantiostylous), chasmogamous, rarely cleistogamous, bisexual or staminate, rarely pistillate; sepals 3, sepaloid; petals 3, petaloid, generally deliquescent at post-anthesis; stamens 3–6, filaments glabrous or bearded, staminodes 1–3 when present; ovary superior, 2–3-locular. Fruits a loculicidal capsule, rarely valves only partially dehiscent or indehiscent. Seeds 1-many per locule, triangular or reniform to quadrangular; embryotega dorsal, semidorsal, lateral or semilateral; hilum punctiform, linear or C-shaped.

The family is characterized by its usually succulent herbs, which can be terrestrial, rupicolous, or aquatic, rarely epiphytes. Leaves spirally or distichously-alternate, sessile or pseudopetiolate; sheaths closed. The inflorescences are thyrsoid, terminal, axillary or basal, composed of few or numerous cincinni, and sometimes subtended by leaf-like or spathaceous bracts. The flowers are ephemeral, with generally deliquescent petals, and the androecium is highly variable. The fruits are most commonly loculicidal capsules but can also be indehiscent or partially dehiscent, more rarely a berry.

Callisia repens is native to tropical America from southern United States to Argentina. However, it can be found naturalized in other continents (Hunt 1986aHunt DR (1986a) Amplification of Callisia Loefl. American Commelinaceae. XV. Kew Bulletin 41: 407-412.; Tseng et al. 2010Tseng YH, Chao CT, Wang CC & Liu SC (2010) Callisia repens (Jacq.) L. (Commelinaceae), a Newly Naturalized Plant in Taiwan. Quarterly Journal of Forest Research 32: 1-6.). In Brazil, it occurs in the Caatinga and Atlantic Forest domains (Aona et al. 2020Aona LYS, Pellegrini MOO & Amaral MCE (2020) Commelinaceae in Flora do Brasil 2020. Instituto de Pesquisas Jardim Botânico do Rio de Janeiro. Available at <http://floradobrasil.jbrj.gov.br/reflora/floradobrasil/FB91>. Access on 2 March 2021.
http://floradobrasil.jbrj.gov.br/reflora...
) (Fig. 3). It can be recognized by its mat-forming habit, decumbent stems, leaf-blades green with vinaceous margins, and anemophilous flowers due to the reduced corolla, expanded anther connectives, and exserted stamens. Callisia repens has not had its conservation assessed yet. Flowers and fruits were recorded from June to August.

Commelina is the largest genus in the family (ca. 230 species) with an almost cosmopolitan distribution, being one of the most complicated taxonomically (Faden 1998Faden RB (1998) Commelinaceae. In: Kubitzki K (ed.) The families and genera of vascular plants. Vol. 4. Springer Verlag, Berlin. Pp. 109-128. <https://doi.org/10.1007/978-3-662-03531-3_12>; Hardy & Faden 2004Hardy CR & Faden RB (2004) Commelinaceae. In: Smith N, Mori SA, Henderson A, Stevenson DW & Held SV (eds.)

). Commelina is easily differentiated by its spathaceous basal bract, inflorescences reduced to (1–)2 fasciculate cincinni, enantiostylous flowers, unequal petals, generally sky blue (sometimes white, lilac and purple, rarely pink, orange and yellow), and X-shaped antherodes (Faden 1998Faden RB (1998) Commelinaceae. In: Kubitzki K (ed.) The families and genera of vascular plants. Vol. 4. Springer Verlag, Berlin. Pp. 109-128. <https://doi.org/10.1007/978-3-662-03531-3_12>; Pellegrini 2019).

Commelina benghalensis is distributed from tropical and subtropical regions of the world (Pellegrini & Forzza 2017Pellegrini MOO & Forzza RC (2017) Synopsis of Commelina L. (Commelinaceae) in the state of Rio de Janeiro, reveals a new white-flowered species endemic to Brazil. PhytoKeys 78: 59-81.) (Fig. 3). It is an annual species, and a great deal of morphological variation can be observed, mainly in the indumentum (varying from sparse to dense trichomes) and leaf-blade size. Despite its morphological variation, it presents diagnostic features like the broadly ovate to obovate leaf-blades and the cleistogamous subterraneous flowers. According to Beentje & Lansdown (2018)Beentje HJ & Lansdown RV (2018) Commelina benghalensis. The IUCN Red List of Threatened Species 2018: e.T177240A120145118.

). Despite the recent reestablishment of C. scabrata Seub. and C. vestita Seub. (Pellegrini et al., in press), C. robusta still presents a great deal of morphological variation in its current circumscription. It can be differentiated from C. scabrata by its leaves scabrid on both sides (vs. adaxially glabrous to sparsely hispid, abaxially hispid to densely hispid, hirsute along the midvein in C. scabrata), the developed upper cincinnus (vs. vestigial in C. scabrata), capsules smooth and tan-colored when mature (vs. verrucate and opaque white), seeds with foveolate to rugose-foveolate testa (vs. smooth), and linear hilum (vs. C-shaped). Commelina robusta has not had its conservation assessed yet. Flowers and fruits were recorded throughout the year.

PhytoKeys 78: 59-81.). It is a rare species in the Atlantic Forest and Cerrado biomes, with most records concentrated at the Amazon Forest (Pellegrini & Forzza 2017Pellegrini MOO & Forzza RC (2017) Synopsis of Commelina L. (Commelinaceae) in the state of Rio de Janeiro, reveals a new white-flowered species endemic to Brazil. PhytoKeys 78: 59-81.). In Espírito Santo, it is known exclusively from the “tabuleiro” region Linhares, growing understory in rainforests (Fig. 8). The floral morphology of C. rufipes is still poorly understood since it is most commonly collected in fruit. It is easily distinguished from most species of the genus by its hirsute vegetative organs with rusty to rusty-brown trichomes, white flowers, and pearl-like fruits. Commelina rufipes has not had its conservation assessed yet. The information available indicates it flowers in June.

Commelina scabrata is endemic to Brazil, recorded for the states of Espírito Santo (Fig. 8), Rio de Janeiro, and São Paulo (Pellegrini et al., in press). Until recently treated as a synonym of C. robusta, it can be easily differentiated by its aborted and included upper cincinnus (vs. developed and exserted), fruits opaque white when mature (vs. tan-colored), seeds with echinate testa (vs. foveolate to rugose-foveolate), and hilum C-shaped (vs. linear). According to Pellegrini et al. (in press), it should be regarded as Endangered (EN). Flowers and fruits were recorded from April to August.

Dichorisandra is one of the largest genera of Commelinaceae (ca. 60 species), with a Neotropical distribution and most of its species confined to the Atlantic Forest domain (Faden & Hunt 1991Faden RB & Hunt DR (1991) The classification of the Commelinaceae. Taxon 40: 19-31.; Evans et al. 2003Evans TM, Sytsma KJ, Faden RB & Givnish TJ (2003) Phylogenetic relationships in the Commelinaceae: II. A cladistic analysis of rbcL sequences and morphology.

The specific epithet honors Dr. Lidyanne Yuriko Saleme Aona (Universidade Federal do Recôncavo da Bahia) for her contributions to the taxonomy of Dichorisandra.

Dichorisandra aonae is endemic to the municipality of Água Doce do Norte (Espírito Santo), growing in rainforest remnants associated with inselbergs, in humid and shaded places (Fig. 9). It is characterized by its vegetative organs, inflorescences, pedicels, sepals, ovary and capsules hirsute to densely hirsute with hyaline to light brown trichomes, leaf-blades strongly discolorous (adaxially dark green with silver stripes and abaxially vinaceous to purple), large flowers (> 2.2 cm diam.), 5 stamens, anthers introrsely rimose (but functionally poricidal), white with upper half or third bluish-purple to purple, globose capsules, and 1–2 seeds per locule. The few seeded capsules are so far unique in Dichorisandra, with the remaining species of the genus presenting (3–)4–6 seeds per locule (Aona 2008Aona LYS (2008) Revisão taxonômica e análise cladística do gênero Dichorisandra J.C.Mikan (Commelinaceae). Ph.D. thesis. Universidade Estadual de Campinas, Campinas. 310p.). It is similar to D. variegata Aona & M.C.E.Amaral and D. hirtella (Nees & Mart.) Mart. ex Schult. f. due to its indumentum. It is further similar to D. variegata due to its silver-stripped leaves. It differs of both species by its hirsute to densely hirsute ovary (vs. glabrous), and globose capsules (vs. ellipsoid). It differs from D. variegata due to its spirally-alternate-alternate leaves (vs. distichously-alternate) and from and D. hirtella due to its leaf-blades with silver longitudinal stripes (vs. leaf-blades without longitudinal stripes). It is also morphologically similar to D. glandulosa due to its small size (up to 50 cm tall), its vegetative organs, inflorescences, sepals, ovary and capsules densely hirsute with hyaline to light brown trichomes, large flowers, 5 stamens, and anthers introrsely rimose (but functionally poricidal) white with upper half or third bluish-purple to purple. However, it can be differentiated by its eglandular hirsute sepals, ovary and capsules (vs. glandular-pubescent in D. glandulosa), leaves discolorous, adaxially dark green with silver longitudinal stripes and abaxially vinaceous to purple (vs. concolorous, green on both sides), capsules globose (vs. cylindric), 1–2 seeds per locule (vs. 3–6), testa light brown to reddish-brown (vs. dark brow).

). Morphologically similar to D. incurva (view comments for D. incurva). However, D. glabrescens has consistently vining stems (vs. scrambling or ascending with decumbent at apex), actinomorphic corolla (vs. zygomorphic), and petals pale blue to lilac (vs. white). This species has been rarely collected in fruits, and seeds are still unknown for it. Thus, our description was complemented with data from Aona et al. (2016b)Aona LYS, Bittrich V & Amaral MCE (2016b) Taxonomic novelties in Brazilian Dichorisandra (Commelinaceae): D. sagittata sp. nov. and D. glabrescens stat. nov. Brittonia 68: 1-9.. The species has not had its conservation assessed yet. The information available in the herbaria indicate it flowers from October to April. Immature fruits were collected in October.

The epithet “glandulosa” makes reference to this species glandular-pubescent inflorescences, sepals, ovary and capsules, which are unique in the genus.

Dichorisandraglandulosa is endemic to Águia Branca (Espírito Santo), growing in rainforest remnants (Fig. 13). This species presents a small stature (up to 40 cm tall), hirsute to densely hirsute stems and leaves, glandular-pubescent inflorescences, pedicels, sepals, ovary and capsules (which are unique in the genus), large flowers (up to 2 cm diam), 5 stamens, anthers introrsely rimose (but functionally poricidal), white with upper half or third bluish-purple to purple, ellipsoid capsules, and 3–6 seeds per locule. It resembles D. pubescens Mart. ex Schult. f. in its small erect habit (40–50 cm tall) and green and densely pilose leaves. However, D. glandulosa has 5 stamens (vs. six in D. pubescens), introrsely rimose and functionally poricidal anthers (vs. poricidal), and glandular-pubescent ovary and capsules (vs. glabrous). It is also similar to D. puberula Nees & Martius due to its 5 stamens, 5 stamens, anthers introrsely rimose (but functionally poricidal), white with upper half or third bluish-purple to purple, and capsules longer than wide. However, D. glandulosa has hirsute to densely hirsute leaves (vs. adaxially glabrescent and abaxially glabrous), and ovary and capsules glandular-pubescent (vs. glabrous). Dichorisandra glandulosa is most similar to D. aonae (see comments above). However, it can be differed by its concolorous leaves (vs. discolorous, adaxially dark green with longitudinal silver stripes, abaxially vinaceous to purple in D. aonae), and glandular-pubescent inflorescences, pedicels, sepals, ovary and capsules (vs. hirsute).

). In Espírito Santo (Fig. 13), it occurs in semideciduous seasonal forests and shaded areas of rocky outcrops. It is morphologically similar to D. glabrescens due to its asymmetric leaf base, floral morphology, 6 stamens, and anthers introrsely rimose (but functionally poricidal) and yellow. However, it differs by its stems scrambling or ascending with decumbent apex (vs. vining in D. glabrescens), and white petals (vs. light blue to lilac). Dichorisandra incurva has not had its conservation assessed yet. Flowers were recorded from August to May.

Dichorisandra neglecta is only known from the type material, collected in Cachoeiro de Itapemirim, southern Espírito Santo (Brade 1957Brade AC (1957) Espécies novas da Flora do Brasil II. Arquivos do Jardim Botânico do Rio de Janeiro XV: 5-20.). The morphologic variation of D. neglecta is still poorly understood, and fruit and seed characters are still unknown. In the present study, intensive fieldwork was done in the region. However, we were unable to recollect this species. Dichorisandra neglecta is currently categorized as Critically Endangered (CR) (CNCflora 2012bCNCFlora (2012b) Dichorisandra neglecta in Lista Vermelha da flora brasileira versão 2012.2.

), but following the IUCN (2012)IUCN (2012) IUCN red list categories and criteria version 3.1, 2nd edition. IUCN, Gland. 32p. recommendations, it should be considered Extinct (EX) since it has been over 50 years since it was last collected. The information provided by Brade (1957)Brade AC (1957) Espécies novas da Flora do Brasil II. Arquivos do Jardim Botânico do Rio de Janeiro XV: 5-20. indicates it flowers in January. It is morphologically similar to Dichorisandra sp. due to its inflorescences perforating the leaf-sheaths, enclosed by peduncle bracts, petals white, and unique dimorphic stamens (the posterior with large and connivent anthers, the anterior with small and free anthers).

). Dichorisandra penduliflora is easily recognized by its shrub-like habit, distichously-alternate leaves, pendulous inflorescences, stamens 5, anthers introrsely rimose (but functionally poricidal), cream to white with the bluish-purple to purple apex, and cylindric capsules. Morphological variation is mainly regarding the indumentum (ranging from glabrous to sparsely hispidulous) and the size of the inflorescence peduncle. D. penduliflora has not had its conservation assessed yet. Flowers and fruits were recorded throughout the year.

Dichorisandra procera is endemic to Brazil, recorded for the states of Alagoas, Bahia, Pernambuco, Sergipe, Espírito Santo, Minas Gerais, and Rio de Janeiro (Aona et al. 2020Aona LYS, Pellegrini MOO & Amaral MCE (2020) Commelinaceae in Flora do Brasil 2020.

). In Espírito Santo, it is found growing understory in rainforests, semideciduous seasonal forests, rocky outcrops, tabuleiro forests, and restinga (Fig. 15). A great deal of variation is accepted for this species but is mainly related to the leaves’ shape and coloration. According to Aona (2008)Aona LYS (2008) Revisão taxonômica e análise cladística do gênero Dichorisandra J.C.Mikan (Commelinaceae). Ph.D. thesis. Universidade Estadual de Campinas, Campinas. 310p., there are no reproductive differences between D. albomarginata and D. procera (Figs. 5s-t; 16c), the only difference being the shape and size of the leaf-blades and the presence or without longitudinal silver stripes. Based on extensive field studies and the cultivation of several specimens, it become clear that these leaf characters are environmentally controlled. When a specimen with silver-stripped leaves (matching the D. albomarginata morphotype) was relocated from a full shade greenhouse at JBRJ to a sunny greenhouse, all newly produced leaves lacked the characteristic silver stripes. After some time, the same specimen was transferred back to the full shade greenhouse and gradually started producing new leaves with silver stripes (Pellegrini, personal observation). Furthermore, during fieldwork in Espírito Santo, young specimens of D. procera were found with silver stripes and mature specimens with or without stripes, either in the same specimen or population (Moraes & Pellegrini, personal observation). These leaf characters are clearly insufficient to sustain both species as distinct (Figs. 16a-b). Thus, we proposed the synonymization of D. albomarginata under the older D. procera. The species has not had its conservation assessed yet. Flowers and fruits were recorded throughout the year.

Dichorisandra striatula is endemic to the municipality of Nova Venécia (Espírito Santo) (Fig. 17), being restricted to inselbergs and semideciduous forests (Moraes et al. 2019Moraes QS, Pellegrini MOO & Alves-Araújo A (2019) New Species of Dichorisandra (Commelinaceae) with Speckled Leaves from Brazil. Systematic Botany 44: 783-789. ). Dichorisandra striatula is morphologically similar to D. glaziovii due to its erect stems, 5 stamens, and yellow anthers, which are introrsely rimose (but functionally poricidal). However, it differs mainly by its leaves speckled with small and discontinuous white stripes and/or spots on the adaxial side, hirsutulous on both sides (Fig. 16f) (vs. broad stripes which are continuous on the adaxial sides, hispidulous on both sides), petals obovate to broadly obovate (Fig. 16g) (vs. petals rotund to broadly rhomboid) and fruits ellipsoid (Fig. 16j) (vs. fruits cylindric). According to Moraes et al. (2019)Moraes QS, Pellegrini MOO & Alves-Araújo A (2019) New Species of Dichorisandra (Commelinaceae) with Speckled Leaves from Brazil. Systematic Botany 44: 783-789. , D. striatula should be considered Endangered (EN). Flowers were recorded from January to July, and fruits were recorded from January to March, July, and August.

Tradescantia zanonia is the most widespread species of the genus, ranging from Mexico to Argentina (Pellegrini 2017aPellegrini MOO (2017a) Siderasis albofasciata sp. nov. (Commelinaceae), endemic to the state of Espírito Santo, Brazil, and the typification of S. fuscata. Nordic Journal of Botany 35: 29-37. <https://doi.org/10.1111/njb.01267>.). In Espírito Santo (Fig. 23), it is recorded growing in rainforest remnants. It is easily recognized by its axillary inflorescences perforating the leaf-sheaths, and sepals that become juicy and atro-vinaceous to black in fruit (giving the impression the fruit is a berry). The species has not had its conservation assessed yet. Flowers and fruits were recorded from March to July and November.

). In Espírito Santo (Fig. 21), it is generally found growing in very humid places. There is a considerable variation in petal shape (ovate to obovate) and coloration (white to pale pink to pink to lilac). Nonetheless, the non-moniliform trichomes in the filaments and areolate-reticulate seeds these characters are diagnostic for specie delimitation. Tripogandra diuretica has not had its conservation assessed yet. Flowering was recorded from December to April.
