noun    (Concise Encyclopedia)

Senna (Cassia didymobotrya).—Gerald Cubitt

Any of several plants, especially of the genus Cassia, in the pea family (see legume), mostly of subtropical and tropical regions. Many are used medicinally; some yield tanbark used in preparing leather. Some sennas are among the showiest flowering trees. In the eastern U.S., wild sennas (C. hebecarpa and C. marilandica) grow up to 4 ft (1.25 m) high and have showy spikes of yellow flowers. Some species are Old World shrubs or small trees.
