''Physostigma venenosum'' (the Calabar bean or ordeal bean) is the seed of a leguminous plant, a native of tropical Africa, poisonous to humans. It derives the first part of its scientific name from a curious beak-like appendage at the end of the stigma, in the centre of the flower; this appendage, though solid, was supposed to be hollow (hence the name from , a bladder, and stigma). ==Growth== The plant is a large, herbaceous, climbing perennial, with the stem woody at the base, up to in diameter; it has a habit like the scarlet runner, and attains a height of about . The flowers, resting on axillary peduncles, are large, about an inch long, grouped in pendulous, fascicled racemes pale-pink or purplish, and beautifully veined. The seed pods, which contain two or three seeds or beans, are in length; and the beans are about the size of an ordinary horse bean but much thicker, with a deep chocolate-brown color.
