Native names : Banuyo ( Tayabas, Samar, Masbate, Burias, Ticao, Camarines ) ; 
lupigui (Cagayan, Isabela) ; melmel, dauer (Cagayan). 
A monotypic genus at present known only from Celebes and the Philippines, 
growing especially near the seashore, but also occurring inland and at considerable 
altitudes. It undoubtedly belongs in the Mimosoideae-Ingeae, although in fruit 
characters it is closer to some of the genera in Mimosoideae-Piptadenieae. It is 
well characterized by its dehiscent pods, the exocarp of which is not transversely 
jointed, and which is free from the transversely septate endocarp, the latter 
forming a somewhat loose, parchment-like, more or less inflated envelope surround- 
ing each seed, quite similar to that of Entada, and doubtless an adaptation 
for dispersal of the seeds by water. The timber is of considerable value, and 
has been considered by Foxworthy, 12 under the head of Banuyo.

Leaves reduced to simple, flat, narrowly lanceolate, somewhat falcate phyllodia, 
G to 11 cm long; heads axillary, solitary, peduneled 1. A. confusa 
Leaves all bipinnate. 
Erect shrubs or small trees with stipular spines; heads solitary or fascicled, 
axillary; pods cylindric 2. A. farnesiana 
Scandent shrubs with non-spinescent stipules and with prickly branches; heads

at least well removed from the upper margin 4. A. caesia 
Leaflets linear to linear-oblong, 1 to 1.3 mm wide, crowded, the costa close 
to the upper margin, at least near the base of the leaflets.
