SCHOMBURGK’S GUIANA PLANTS. 85 
was founded only on an accidentally abnormal state of Neu- 
rocarpum ellipticum, and the Mexican plant, since added as a 
second species, is a Galactia in the same abnormal apetalous 
state so common among Leguminose. I am therefore truly 
happy to be enabled to dedicate this beautiful tree to the cele- 
brated traveller and naturalist whose name is so intimately con- 
nected with the history, both physical and moral, of so large 
a portion of the South American continent. The Martiusia 
excelsa, belongs unquestionably to Swartziee, and is nearly 
allied to Zollernia, but it also tends to connect that tribe with 
Cassiee, of which it has in some measure the corolla and 
stamina. The calyx is also more regular in its dehiscence, 
though still valvular.

arborescens, Aubl. Pl. Guian. II. p. 934. t. 355.—Sw. parvi-

Parine near the Meretani mountains, Schomburgk.— 
Although my single specimen has the leaves usually ternate, 
it has also two or three unifoliate leaves with a very short 
Petiole; and in De Candolle’s figure, there is one trifoliate 
leaf with a winged petiole. I am therefore induced to refer 
here the synonym of De Candolle above quoted. 
Vogel is evidently right in referring Riveria nitens of 
Kunth, to Swartzia, and it appears very near to S. triphylla, 
if not the same species.
