46 ASCLEPIADES. 
To this genus belongs D. Rafflesiana ? 
All the leaves have the same direction, and are subimbri- 
cate ;—very irregular-looking for such organs.

Of this genus I have met with three species, all agreei 
in habit, shape and zstivation of corolla, and peculiar shap 
of coronate leaflets.
