Rorto Alegre, prov. Rio Grande do Sul (Tweedie). 
Tweedie’s specimens have no ^ flowers ; and as these off'er 
many points of accordance with my plant, I have considered it 
the ? of the same species, although the leaves are more oval, 
generally smaller, darker, more opaque, with less prominent 
nerves and reticulations, and not distinctly 3-nerved at base, as 
in the other instance. I found the plant in Nov. 1837, in the 
deep forest on the Corcovado, climbing to the height of the 
loftiest trees ; its main stem was at least 4 inches in diameter ; 
the young branchlets, the rachis of the panicles, and the brac- 
teoles are rufo-puberulous, while all the rest of the plant is quite 
glabrous. The leaves are 2| inches long, 1^ inch broad, chan- 
nelled and subrecurved at the apex, with undulating entire 
margins ; the petiole, slightly curved at the thickened apex, is 
in the ? | inch, in the f inch long, being articulated at its 
insertion in the cupuliform node of each axil. The panicle 
grows out of an axillary tuft of hairs, has a slender pubescent 
rachis about 6 inches long ; its branchlets, about 3 lines apart 
and 6-8 lines long, are either solitary or two or three are fasci- 
culated together, each being corymbosely divided ; the expanded 
flower is 1 line in diameter, the rotate petals are whitish, and 
half the length of the somewhat greenish sepals. The axillary 
$ panicle is 6-9 lines long; but the raceme-like aphyllous 
flowering branch is 4 inches long ; its corymbulose branches (or 
panicles) are stouter than in the , and are 6-9 lines long.
