1. A. lucida, Benth.; Lond. Jour, of Bot. iii. (1844) 86. Syn. Mimosa

A large tree ; glabrous, peduncles and calyx only slightly pubescent. 

 Common petiole 3-5 in. long, pinnae 1-2 pair ; leaflets 1-3 pair, subcoria-

 Peduncles fasciculate, paniculate, bearing heads of 6-10 sessile flowers. 

 Corolla 4 times the length of calyx. Pod linear, straight, 8-10 in. long,
