Hexisea Lankesteri is a member of the group for which 
Dr. Rudolf Schlechter has proposed a new generic concept 
under the name Fractiunguis. It is closely allied to Hexisea 
cuniculata (Schltr.) Ames comb. nov. (Fractiunguis cunicu- 
latus Schltr. in Fedde Repert. Beihefte 19 (1923) 31), but 
differs in the more robust habit, in the size of the flowers, 
and in the outline and calli of the labellum.

Epidendrum caligarium was originally reported as a 
native of New Grenada by Wentworth W. Buller, who sent 
specimens to the Royal Gardens, Kew, with the following 
note: “This Epidendrum has quite the habit of myrianthum. 
The general appearance of the flower also resembles that 
species, but the side lobes of being so much divided seem to 
make it a separate species. It came from New' Grenada.”
