in botany, is a genus of Indian plants, of which the characters, as given by Sir William Jones in the Asiatic Researches, vol. ii. p. 351, are these. The calyx is five-cleft, the corolla has five equal petals, the pericarpium a thorny legumen and two seeds, the leaves oval and pinnated, and the stem armed. "The seeds (says the learned President) are very bitter, and perhaps tonic; since one of them, bruised and given in two doses, will, as the Hindoos assert, cure an intermittent fever."
