80 MR. G. BENTHAM’S SYNOPSIS OF DALBERGIEZ, 
When 1 saw Humboldt's specimen at Paris in 1857, it appeared to 
me quite distinct from the P. villosum; but I have not had the oppor- 
tunity of carefully comparing it. | 
Among the species enumerated by DeCandolle or subsequent writers 
under Pterocarpus, the P. sapindoides, DU.,is an Andira; P. Peltaria, 
DC., is Viborgia fusca ; the rest of his section Ateleia forms a new genus 
under that name among Cesalpiniee ; P. australis, Endl., is a Millettia ; 
Amphymenium mediterraneum, Mart., is a Martia.
