Aeschynomene indica - Linnaeus
Fabaceae (Bean) Family
The leaves are alternate, petiolate, and odd-pinnately compound. The leaves are sensitive to touch and will fold up when disturbed. Each leaf has 50-70 oblong or linear-oblong leaflets. The leaflets have a single obvious vein and are glabrous.
The flowers are produced in axillary racemes of 3-6 flowers; appearing in late spring and early summer. The rachis (flower bearing stem) and peduncle (flower stalk) is glandular pubescent. Flowers resemble small butterflies; yellow in color, fading to orange with age.
The fruit is a segmented legume that is glandular pubescent. The legume breaks into 1-seeded segments.
The plant occurs throughout the tropical and subtropical areas of the world. It is sometimes planted as a green manure, and extracts from the plant are used in herbal medicine and as a spermicide. Large spongy stems are used as floats or to build rafts. The seed contain rotenoids, and the foliage can be toxic to ruminants.
