Professor WrLLDENow has remarked in his work above quoted, that this most rare and curious 
plant constitutes a distinct genus; but I d o et think with him that it has a very near Fancy to 
orum or Aerides. It approaches rather opinion to some of the North Ame 7 
thusas, and Swarrz in his first dissertation had hated it not far from one, the luaidaniste yar a

The poetic name now selected for it, in conformity to one of Liwnr’s canons, is the more ap- 
propriate, as the stigma is totally covered. I am indebted to Mrs. Hatieurton of Halifar in Nova
