The habit of this species is precisely that of a small creeping Bulhophyllum, to 

 which genus Lindley referred it, remarking : " Tiiis singular little species has flowers 

 like miniatures of Aconitum Lycoctonum. • For petals there- are only two minute rudi- 

 ments; the lip resembles that of some Polystachyas, and the column has two deep, 

 fleshy, purplish cheeks."

A peculiar little plant allied to the preceding. The petals are much reduced, and 

 are easily overlooked.
