Traditionally the castor bean, Ricinus communis L., has been used as a representative endospermous dictotyledon in the study of seed types and germination in elementary botany courses. Such usage occasions great hazard to students, since the seeds are extremely toxic, causing death if taken internally or blindness if rubbed into the eye (Wheeler, 1954). Because of the dangers of the castor bean, Wheeler recommended several legumes which possess endosperm as substitutes. Most of these are either not available in the eastern United States or are rather small for satisfactory use.
