G-. King & R. Pantling— New Orchids from Silihim. [No. 3, 
the sepals, broadly oblong, flat except for a slight depression below the 
column; the side lobes short, subulate, spreading ; the apex deeply 
bifid, the lobes oblong-acute, slightly divergent at their apices. 
Column with two fleshy wings. Anther membranous; the pollinia 
ovate, flattened and of a dark orange colour. 
Sikkim: at Labha, elevation about 6,000 feet p In flower in July. 
(Both locality and elevation are however doubtful). 
This belongs to same group as 0. caulescens , Lindl. and 0. Wight - 
iana, Lindl. 
Oberonia longilabris, n. spec. Stems caulescent, slightly tufted, 
erect, slender, 2 to 3 in. long. Leaves narrowly ensiform, acute, 1 to 
1*5 in. long, and *2 in. broad. Racemes slender, 2’5 to 35 in. long, 
nodding; their stalks ‘5 to 1*25 in., ebracteate. Flowers minute, rather 
sparse, green. Bract lanceolate, erose, much exceeding the stalked 
ovary. Sepals ovate, entire. Petals linear, blunt. Lip oblong, three 
times as long as the sepals, with two small rounded lobes at the very 
base, the apical lobes broadly lanceolate, sub-divergent, acute, the 
sinus apiculate, the surface of the lip with a lanceolate depression 
extending from near the sinus to the column and there becoming 
deeper. Column with small stout wings. Pollinia orange. 
Sikkim : at Songchongloo, elevation 6,000 feet ; in flower in July. 
A species near O. caulescens , Lindl. 
Oberonia micrantha, n. spec. Acaulescent, height of whole plant 
2‘5 inches. Leaves narrowly-ensiform, sub-acute, *5 to L5 in. long, and 
from T to *15 in. broad. Racemes about 1'25 in. long, on very short 
bracteate stalks. Floivers numerous, very minute, verticillate. Bracts 
linear-lanceolate, erose, equal to or slightly exceeding the ovary. 
Sepals broadly ovate, entire, spreading, minutely papillose externally. 
Petals narrower than the sepals, ovate, entire, recurved. Lip in general 
outline sub-rotund divided into a basal and apical part by deep lateral 
sinuses : the basal part concave, fleshy, its edges almost entire; the 
apical part transversely elliptic, thinner than the basal, with an acute 
apiculus and irregularly erose-dentate edges. 
Sikkim : at Tendong, elevation 6,000 feet; in flower in July. 
The nearest allies of this very distinct little species are O. myri - 
antha, Lindl. and O. demissa , Lindl. 
Oberonia parvula, n. spec. Acaulescent, not tufted or very slight¬ 
ly so : the height of the whole plant L25 to 2 in. Leaves two or three, 
*5 to nearly 1 in. long, and *12 to *25 in. broad, lanceolate, acute. 
Raceme ‘75 to 1 in. long, on a slender stalk about half as long. Flowers 
very minute, densely crowded, not verticillate. Bract lanceolate, as 
long as the stalked ovary. Sepals ovate, entire, the laterals larger
