330 Gr. King & R. Pantling — New Orchids from SilcJcim. [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 ? 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 

 25 inches. Leaves narrowly-ensiform, sub-acute, - 5 to 1"5 in. long, and 

 from 1 to "15 in. broad. Racemes about 125 in. long, on very short 

 bracteate stalks. Flowers 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-i'otund 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 125 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 ovaiy. Sepals ovate, entire, the laterals larger
