OBERONIA. 13 
Prate 15.—Obercnia rufilabris, Lindl. Two plants, of natural size, Fig. 1 a flower seen from 
the front, 2 clinandrium and part of column, 3 floral bract from the lower part of a raceme, 
4 floral bract from the upper part of a raceme, 5 cap of anther, 6 pollinia; all enlarged.

Caulescent. Stems tufted, slender, 2 to 3 in. long. Leaves linear-ensiform, acute, 
‘75 to 15 in. long and ‘2 in. broad. Inflorescence three times as long as the 
leaves, much decurved; the peduncle about as long as the uppermost leaf, terete, 
slender,  ebracteate; the raceme tapering to the apex; floral bracet lanceolate, 
` acuminate, slightly erose, much exceeding the stalked ovary and about as long as 
the lip. Flowers yellow, minute (‘06 in. long’, scattered. Sepals ovate, entire. Petals 
linear-oblong, sub-truncate, entire, spreading like the sepals. Гір oblong in general 
outline, three times as long as the sepals, with two small rounded auricle-liko lobes 
at the very base; the apical lobes broadly lanceolate, sub-divergent, acute, separated 
by a sub-triangular sinus; the middle part of the lip (mesochile) with a lanceolate 
depression extending from near the column to near the apical sinus. Column with 
small stout wings. Pollina orange. 
Sikkim; at Song-chong-loo, elevation about 6,000 feet: at Namgah, elevation 
about 5,000 feet; Pantling No. 227; in flowerin July. 
The concavity on the lip is deep just under the column, becoming shallower 
towards its apex. The winged column is very unusual in the genus. This species 
approaches О. caulescens, Lindl.; but differs in its longer stem, ebracteate peduncle, in 
its flowers not being in the least whorled, and in having truncate petals and a lip 
with shorter lobes.

19. OBERONIA AURICULATA, new species. 
Stem 1 to 1:5 in. long. Leaves linear-equitant, acuminate, not falcate, *5 to 1 in. 
long and “15 to ‘2 in. broad. Inflorescence erect, three times as long as the leaves; 
peduncle less than one inch, naked or with a few bracts; raceme slender, sparsely- 
flowered; floral bract lanceolate, erose. Sepals ovate, sub-acute, the lateral pair reflexed 
on the slenderly stalked ovary. Petals erect like the dorsal sepal, narrowly oblong, 
blunt, the margins erose. Zip longer than the sepals and petals, oblong, narrowed 
at the truncate base, widening upwards, the apex divided into two obtuse diverging 
oblong lobules by a deep triangular sinus mucronate at its apex; lateral lobes none, 
but at each end of the base a small rounded auricle with a triangular depression 
inside it. 
Sikkim; at Sureil and Rungbee at elevations of about 6,000 feet; Pantling No. 
166; in flower in May. 
Allied to 0. caulescens, Lindl, but in that species the lip has rather large basal 
lobes, and the lobules of the terminal lobe are produced into tails; the M шоге- 
over, are entire, not erose as in this.
