This concept differs from the variable YY. squalens in 
two particulars. First, it has unifohate pseudobulbs, 
whereas VY. sqgualens commonly has bifoliate (or very 
rarely trifoliate) pseudobulbs. Secondly, it has floral 
bracts three or four times shorter than the pedicellate 
ovary, Whereas XY. sqgua/ens has floral bracts that vary 
from little shorter than the pedicellate ovary (in the Y. 
scabrilingue torm) to longer than the flower. Judging 
from the floral analysis, the flower appears to be identi- 
‘al with a small form of _Y. squa/ens, except that the 
mid-lobe of the lip appears to be relatively slightly larger 
in proportion to the entire lamina.

Lycaste peruviana Rolfe in Kew Bull. (1910) 160. 
Judging by the description, supplemented by several 
flowering scapes of LL. peruviana (trom the Kew Herbar- 
ium) which may be regarded as typical, it seems reason- 
able to consider this concept as a variant of LL. fimbriata. 
The latter species appears to be very variable, both in 
vegetative and floral proportions, in the degree of tooth- 
ing of the mid-lobe of the lip and, to a lesser extent, in 
the color of the flowers. 
There do not appear to be any morphological differ- 
ences between the concepts, however, and the only dis- 
parities seem to be the strikingly smaller size of the leaves 
and floral segments of LL. peruviana, whose sepals and 
petals are described as light tawny-brown, as contrasted 
with greenish, white or cream-color in L. fimbriata. 
The exact source of L. peruviana is not recorded, the 
plant having been collected in Peru by Forget and intro- 
duced by Messrs. Sander & Sons of St. Albans, England.
