Phaseolus. Phaseolus vulgaris L. Common Kidney or String Bean. (Fam. Leguminosae.)— Of this species there are some 70 cultivated varieties. Soltsien found an alkaloid, phaseoline, in the legumes of the common bean. He, during a toxicological analysis, traced the source of the alkaloid which might, under other circumstances, have been mistaken for a ptomaine, to the beans found in the stomach under examination. The new substance is not crystallizable in the free state, but it crystallizes as a hydrochloride. (A. Pharm., 1884.)
