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 ; ita root is suffruticose, spreading 

 lrv to 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- 

 ie ss, covered with many rugous tubercles, and beset with 

 s hort, close, downy, viscid hairs ; they are 4 to 6 lines long, 

 an d 1 li ne broad j a fleshy, raised gland is seen on each side 

 of the petiole in the usual place of stipules ; the peduncle is 

 s hort, axillary, 1 line long ; the calyx is 3 lines in length, and 

 cleft nearly to the base into 5 unequal, spathulate, obtuse, erect 

 * A representation of this specie* ia given in Plate 24 of the " Illustra- 

 tes of South American Plants."
