This is the largest species of Oberonia found in Sikkim; it has the peculiarity of 
having all its leaves curved in the same direction. It falls into the group with 
0. myriantha, Lind]. and 0. ferruginea, Parish, its nearest ally being probably the latter, 
from which, however, it differs conspicuously in having its petals and lip entire instead 
of fimbriate. 'The basal lobes of the lip, moreover, are broad, not narrow as in 
O. ferruginea, and the apical sinus is obtuse, instead of acute as in that species. Speci- 
mens recently received from Mr. R. L. Proudlock, collected by him in the Nilgiri 
Hills, exactly agree with those collected: in Sikkim. It had not been previously 
suspected that O. ensiformis occurred in Southern India. |

Siem very short. Leaves narrowly oblong, tapering to the sub-acute apex and also 
slightly to the base, sub-faleate, “5 to З in. long and ‘25 to ‘5 in. broad. Inflorescence 
about as long as the longest leaves, erect or decurved; the peduncle about “225 in. long, 
ebracteate, axillary; the raceme five or six times as long, truncate at the apex, densely- 
flowered; the rachis rather stout; floral bact as long as the shortly-stalked ovary, 
lanceolate, sub-acute, its edges obscurely crenulate. Flowers minute, (°05 in. long) 
reddish-brown, densely whorled. Sepals sub-equal, ovate, entire, all reflexed and lying 
on the ovary. Petals elliptic, obtuse, erose-dentate, spreading. Lip equalling the sepals 
in length. but much broader, 3-lobed; the lateral lobes oblong, blunt, faleate, erose- 
dentate, divergent; the terminal lobe quadrate, orbicular, with broad emarginate apex 
and erose-dentate edges, Hook. fil Ic, Plantar., t. 1785 В; Fl. Вт, Ind. V, 630.
