This genus in the old world corresponds in some measure 
to Calliandra in the new world. The species have most of 
them been referred to Acacia on account of the pod, which 
is precisely that of some species of that genus, but the 
flowers are nearer to those of /nga, under which name a few 
species have also been published. "When the specimens are 
perfect Albizzia is easily distinguished from Acacia, Zygia, 
and Serianthes by the flower, from all other Jngoid genera by 
the pod. Where the pod is wanting, it may be known from 
Pithecolobium, the only remaining Ingoid genus in the old 
world, in some cases by the large heads of flowers, the form 
of the corolla and long stamina; and the small-flowered 
species may be distinguished from the sections Unguis-Cati 
and Concordia by the want of spines, from Clypearia by the 
inflorescence. It is only in the case of the few species of 
the section Cathormion that there is any difficulty of deciding 
to which genus they belong without seeing the pod, but 
even here there are differences in habit which seldom leave 
much doubt.
