RUTACEÆ. 419 
A certain number of Quassias have been separated as a tribe, under 
the name of Picramniee, whose carpels, instead of being independent 
below, are united into a plurilocular ovary. We remark among these 
plants Zariri (figs. 454, 485), subsequently called Picramnia, consisting 
of American trees or shrubs, very bitter, with alternate, imparipinnate 
leaves, analogous by these characters to those of most of the true 
Tariri (Picramnia) polyantha.

Quassias. Their flowers are dicecious, 3—5-merous, with, or more 
rarely without, a corolla, and having stamens equal in number to the 
petals, to which they are superposed, Each of the two or three cells 
of their ovary contains two collateral descending ovules, with exterior 
and superior micropyle; their fruit is a mono- or oligospermous berry, 
with exalbuminous seeds. Spathelia, consisting of trees of Western

trifoliolate leaves, the male flowers said to be grouped in catkins, 
and a drupaceous fruit, whose single seed contains an embryo with 
folded cotyledons. Harrisonia (figs. 486-490), consisting of shrubs
