RUBIACEÆ. CLXXI. Psycnorria. 
herbs, natives within the tropics. Leaves opposite, petiolate. 
Stipulas variable. Peduncles sometimes axillary, but usually 
terminal. Flowers disposed in panicles or corymbs, rarely tetra- 
merous, but almost always pentamerous; sometimes, however, 
there are tetramerous and pentamerous flowers to be found at 
the same time, and on the same plant. The species are very 
numerous and truly intricate, therefore difficult to define. 
§ 1. Peduneles axillary.—Perhaps all the species belonging to 
the present section belong to the genus Ronabea.

Fernandez, where it is called Peralillo according to Bertero. 
Hippotis pyrifdlia, Bertero, mss. Bertero thinks it may only 
be a variety of the preceding species, but it is much larger ; 
he did not meet with the flower; but if its structure prove 
to be the same as the other, both merit being raised to the rank 
of a genus according to Arnott.
