On the basis of additional collections referable to this 
species, it appears advisable to point out several discrep- 
ancies from the original description. These specimens 
show stems as long as 8.5 cm., whereas the description 
cites amaximum length of 4 cm. The leaf, which is de- 
scribed as oblanceolate, appears to be rarely narrowly 
obovate, and it attains a length of 9.5 em., rather than 
the cited maximum of 7.5 cm., and a width of 2.5 em., 
as contrasted with 1.5 cm. The flowers are often mark- 
edly larger than specified, the dorsal sepal attaining a 
length of 6.7 mm., rather than the cited 8mm. The lip, 
when viewed from the front, is transversely ovate, broad- 
ly rounded or rounded-truncate in front commonly with 
a minute apicule in the middle and with the basal portion 
occupied by a transverse fleshy bilobed callus. As de- 
scribed and drawn, the lip is semiorbicular with a trun- 
cate apex and a transverse hollow in the middle.
