oped claw and are either shorter than or about equal to 
the mid-lobe. In Orcumackak 4 (1910) 240, I directed 
attention to the lack of satisfactory characters separating 
H.clypeata from H.lactiflora. The place of origin of the 
lateral segments of the labellum had to be relied on for 
specific distinction; the lateral segments being basal or 
nearly so in H.clypeata and conspicuously above the base 
of the labellum in HZ. lactifiora. The Honduranian speci- 
mens indicate that this is a very weak distinction and also 
indicate that the point of origin of the lateral segments 
of the Jabellum is a doubtful guide to specific separation. 
Habenaria spithamaea Schltr., a native of Guate- 
mala, is probably a variant of this species. 
Habenaria clypeata is rare and heretofore has been 
known only from Mexico and Guatemala.

The Honduranian specimens which I have referred 
to Habenaria crassicornis differ from the type in having 
the segments of the labellum and petals inconspicuously 
papillose. At most there are papillose protuberances at 
the base of the anterior segments of the petals and at the 
base of the lobes of the labellum. The mid-nerve of the 
sepals, and the ovaries, on the other hand, are conspicu- 
ously papillose. 
I suspect that Habenaria quinquefila Schlitr., a na- 
tive of Guatemala, is a very close ally of H.crassicornis 
and doubtfully separable from it.
