Cyanogenesis in plants. Part III.—On Phaseolunatin, the cyanogenetic glucoside of Phaseolus lunatus

Abstract

Phaseolus lunatus is an annual plant, probably indigenous to South America, but now generally cultivated throughout the tropics, where its edible bean is used as a vegetable. The plant presents much the same appearance as the common French bean, but the flowers are smaller and more numerous, whilst the pods are crescent-shaped and contain only two or three seeds.
