 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-edo-e of its stem ; but though the tank was 

 suri'ounded 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,']
