The stipitate flowers and the form of the calyx and corolla are not unlike those oiLinffoides i but their 

 indumentum is densely crisped, and the pod is totally diflferent. Poiteau^s specimen in

The discrimination of species in this section is attended perhaps with greater difficulty than iu any 

 other Mimosete. The foliage and flowers often show more diflPerence between different specimens of one 

 species than between different species, as characterized by widely different fruits. The majority of herba- 

 rium specimens are without fruits, or, when in fruit, the matching them with flowering ones is often very 

 uncertain. Moreover the pod frequently acquires its characteristic form only at the last stage of ripenin
