Without the perfect fruit it is impossible to say whether this is 
a Hirea allied to H. ambigua and argentea, or a Tetrapterys of 
the section Pentapterys, which, as observed by A. de Jussieu, is 
closely allied to those species. The inflorescence is certainly that of 
H. ambigua and argentea, but the lateral wings of the very young 
fruit appear to be as distinctly divided, as in Tetrapterys.

cated by Prof. De Candolle. The fruit is precisely that of my 
Brazilian specimens, the leaves intermediate between those of 
Salzmann's specimens, mentioned by A. de Jussieu, and those of 
the more common Brazilian form figured in St. Hilaire's Flora.
