apical parts. This fleshy rim crosses the disc in a circular line 
at the point where the margin is indented to give the subpan- 
duriform aspect described above. The labellum of M. Mackin- 
nonii, as it appears in specimens of the type number preserved 
in my herbarium, is more strongly trilobed in front of the col- 
umn than the labellum of MZ. propinqua. This trilobed condition 
is clearly shown in the analytical drawings on plate 95 of Du- 
thie’s Orchids of the Northwestern Himalayas (Ann. Roy. Bot. 
Gard. Cale. 9, pt. 2 (1906)). From the tips of the falcate basal 
lobes of the labellum to the tips of the terminal lobules M. Mac- 
kinnonii, in specimens before me, measures 4 mm. in length. 
The labellum of M. propingua measured similarly is 5 mm. long. 
From the material I have examined, M@. Mackinnoni, while it 
sometimes bears three leaves, is usually bifoliate. All of the 
specimens in my herbarium, in fact, are bifoliate. IZ. propinqua, 
on the other hand, usually has a well-developed third leaf, and 
from the material examined would seem to be rarely bifoliate. 
These differences coupled with the widely separated habitats of 
the specimens may be taken as safe guides to specific differen- 
tiation.
