A sketch of the panicle with a drawing of a solitary 
flower (natural size) and a single enlarged lip of Odonto- 
glossum tetraplasium from the Reichenbach Herbarium 
shows that this concept cannot reasonably be separated 
from O. angustatum Lindl. (1837), as represented by a 
photograph of the type specimen from the Lindley Her- 
barium bearing a pen drawing of the callus on the lip. 
The vegetative parts were lacking in the type specimens 
of both species, but these were supplied for O. angusta- 
tum by a subsequent collection mounted with the Lind- 
ley type. 
Judging from the description and floral analysis, Odon- 
toglossum bellum is also a form of this variable species. 
O. bellum appears to be quite as large throughout as 
typical O. angustatum, but the sepals are not so elongate- 
acuminate as in many forms of the latter. The lip which 
is described and shown as obtuse and apiculate, is not very 
dissimilar to the acute lip of Vargas 2888 and Vargas 
3664 which have been determined as O. angustatum.
