Though variable as to foliage, the species of this section 
are readily known by the remarkable way in which the 
branches of the panicle and peduncles are inserted, several 
together, one immediately above the other, in vertical lines. 
The flowers are much like those of the small-flowered Albiz- 
zie, the pod is nearly that of Adaremotemon, but usually 
broader and more sinuate, and in the few cases where I have - 
seen the seed, it appears to be destitute of any fleshy 
arillus.
