New ORCHID. 
OpoNToGLossuM (Leucochilum) mazillare; sepalis lanceolatis acutis peta- 
lisque latioribus sanguineo-maculatis, labello ovato acuto integro basi 
maculato appendice baseos maximä concavá carnosá glabrä luteá extus 
bilamellatà column: apterae feré longitudine. 
We have only seen one flower of this beautiful plant, 
which might at first ‘sight be mistaken for O. Cervantesi. 
It is, however, readily known by its wingless column, and 
especially by the presence of a very large yellow appendage, 
seated at the base of the lip, and scarcely shorter than the 
column. Such an appendage exists in all the Toothtongues, 
but it is usually inconsiderable, and never to be compared in 
size with this. We are unacquainted with the native country 
of this species; but its great resemblance to O. Cervantesit, 
nebulosum, Rossii, &c. indicates Mexico. The specimen now 
described was received from C. D. Warner, Esq. in Sep- 
tember last. |
