Mr. Horne has found (No. 533) in the Seychelles in the woods of Mahe at an 
elevation of 2000 feet, an Asclepiadaceous climber of similar habit of which the 
flowers are at present unknown. It is glabrous in all its parts, with distinctly 
petioled coriaceous glossy lanceolate acuminate leaves 3-4 in. long cuneate at the 
base, flowers few in short-peduncled cymes in the axils of the leaves, follicles 3 inches 
long naked firm clavate acuminate.
