A genus evidently allied to Alsodeia, Paypayrola, Aubl. (which, as 

 illustrated by Tulasne, in Ann. Sci. Nat. 3d ser. 7, p. 368, appears to 

 differ from Alsodeia principally in the inappendiculate stamens), and 

 Pentaloba, Lour., which Mr. Brown long since stated to be congeneric 

 with Alsodeia, if it should prove to have a capsular fruit.* From these 



* Prof. Arnott (in Mag. Zool. & Bot. 2, p. 543), in uniting these two genera, has 

 adopted the older name of Pentaloba; but the inappropriateness of this name even for 

 Loureiro's own plant, in which Mr. Brown found only three placentae, should forbid its 

 superseding the long-admitted name of Alsodeia.
