ORCHIDACEtE 



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 M. 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. Calc. 9, pt. 2 (190G)). 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. propinqua measured similarly is 5 mm. long. 

 From the material I have examined, M. Mackinnonii, while it 

 sometimes bears three leaves, is usually bifoliate. All of the 

 specimens in my herbarium, in fact, are bifoliate. M. 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.
