Morphologic features observed in copper chloride crystals formed from the extracted sap of common beans (Phaseolus vulgaris L.) are presented. Various organs namely root, leaf, steam, flower and seed, taken from each of three different varieties were utilized. Some new terms are introduced for the description of the crystals. Identification of varieties and plant organs is made possible by the variation in the morphology of crystallization patterns formed in the presence of liquid extracts from the various organs studied.
