panding during the forenoon. Stamens within the tube: 
filaments hairy at the base: anthers oblong. Pistil: Germen 
superior, 2-celled: Style filiform: Stigma of two round lobes. 
Capsule globular, large, enclosed in the persistent calyx, 2- 
celled, 4-valved, 4-seeded: Seeds obsoletely triangular, hairy 
on the angles. 
I found this plant on the edge of a small tank, growing 
equally on land and water, covered with flowers and ripe 
fruit in December, and producing abundance of fibrous roots 
all along the under-edge of its stem; but though the tank was 
surrounded with bushes, the stems showed no tendency 
whatever to ascend from the ground. The voluble appear- 
ance which the individual represented in the accompanying 
plate appears to assume, is more a contrivance of the artist, 
whereby to display a larger portion, than a faithful exhibition 
of its general mode of growth. Yet it is not altogether 
unnatural, as some specimens have occasionally a disposition to 
twist at their extremities; caused by the efforts made by the 
young shoots to penetrate through the thick green mat which 
the plant forms. 
[As it appears doubtful whether this be the real Conv. uni- 
florus of Burman’s Fl. Ind., and assuredly it does not well 
accord with the figure of that author, Dr. Wallich has, with 
much Propriety, separated it in his valuable Catalogue, and - 
given it the name here adopted.—H.]
