* The section Amphigena may prove to be identical with the previous sec- 
tion Aristaria. The latter is only known to me from a drawing of D. Telipo- 
gonis in Herb. Kew, made from a type specimen in the Schönberg Herbarium. 
It shows a small plant similar in many parts of its floral structure, and especially 
in the aristz of the sepals, to D. tenuis. But the spur is dependent and the 
leaves synanthous, different in shape, and apparently wanting the peculiar 
sheath of D. tenuis; as, moreover, there were no means of determining the 
nature of the pollinary gland or glands, or the character of the tuber, I have 
thought it better for the present to keep the sections distinct.
