Upper Guinea. On the Niger, T. Vogel I Ansell ! 

 Lower Guinea. Angola, Golungo Alto, Dr. Welwitsch ! 



The description of the fruit is from Dr. Welwitsch 's specimens, which agree as to 

 flower and foliage with the type-specimens from the Niger.

 sometimes 1 ft. or more in length; rachis of the spike puberulous, rough 

 with the minute persistent bases of the short pedicels of the fallen 

 flowers. Bracts at flowering. Flowers about 2 lines long, " white."

 sessile, multiovulate Legume linear, compressed or turgid over the 

 seeds ; usually incurved or falcate, 2-valved ; valves coriaceous, entire.

A small genus of Tropical Asia, of which one species, with long curved or twisted 

 legumes, the endocarp when dry pale straw-coloured with a satiny sheen and brilliantly 

 scarlet seeds (A. pavonina, L.), has been introduced into the New World, and is doubt-
