(Tribe Amnersrieæ. Tropical America and Africa.) 
The two Aubletian genera Vouapa and Outea had long since been united under 
Schreber’s name Macrolobium, adopted by De Candolle; but, at the time of working up 
Schomburgk's Guiana Leguminosæ for Hooker's ‘Journal of Botany ' (vol. ii. p. 95), it 
appeared to me, from the materials we then possessed, that the bifoliolate Vouapas might 
always be distinguished from the pinnate-leaved Outeas by the pod, and that both differed 
from the African Anthonothas, in their simple inflorescence at least, if not in the pod also. 
Now, however, the accession of several American as well as African species shows that 
these differences are by no means constant ; there is considerable diversity in the pods of 
different species in both the American groups; and one American species, M. limbatum, 
Spruce*, has precisely the inflorescence previously supposed to be characteristio of the 
African ones. The latter may, however, still be retained as a section, distinguished 
larger and less oblique than in most of the American ones, and 
by the pinnate leaves, | 
gly minute hairs, whilst the American are
