smooth, the supporting column being enveloped by a 
fleshy annular 2-lobed disc, which invests the base of the 
ovarium: the style is compressed, 2-grooved, and declinate 
at summit; the stigma is flattened, truncated, somewhat 
tubular, with an erect edge, containing within its cavity 2 
globular, papillose, viscid glands. The capsule is small, 
obovate, smooth, and enclosed within the persistent calyx, 
2-celled, 2-valved, each valve being entire, notched at the apex, 
with sutural, scarcely introflexed margins. The seeds are 
oblong, rounded, with the hilum on its ventral face, dark 
brown, reticulately areolar ; the embryo, enclosed in fleshy al- 
bumen, is terete, and slightly curved at the junction of the 
cotyledons with the radicle, the latter being twice the length 
of the former, which are slightly compressed, somewhat 
broader, and ovate.*

I found this plant growing in moist places in the neigh- 
bourhood of Buenos Ayres; its root is suffruticose, spreading 
into many branching prostrate stems, which are of purplish 
hue, rugous and spreading at the axils ; the leaves are often 
fasciculate, linear, obtuse, spathulate, rather fleshy and vein- 
less, covered with many rugous tubercles, and beset with 
short, close, downy, viscid hairs ; they are 4 to 6 lines long, 
and 1 line broad; a fleshy, raised gland is seen on each side 
of the petiole in the usual place of stipules; the peduncle is 
short, axillary, 1 line long ; the calyx is 3 lines in length, and 
cleft nearly to the base into 5 unequal, spathulate, obtuse, erect 
segments, which are fleshy and covered with glandular hairs ;
