ribbed, clothed at the base with three or four short membranous sheaths “95 to “5 in. 
long, and further up with two or three herbaceous pale-green tubular sheaths 1 in. 
long. Raceme longer than the peduncle; fora! bract lanceolate, as long as the 
stalked ovary, deflexed to the rachis, the bracts of the lowest flowers longest. Flowers 
15 іш. long, yellowish, flushed with dull purple. Sepals elliptic, sub-obtuse; the 
dorsal erect, its margins revolute; the lateral pair recurved, the linear petals resting 
upon them. Jip almost flat, ovate, the apex blunt, the margins entire, the base with 
two broad blunt sub-faleate erect lobes, Arms of the column stout, notched, Lip of 
the anther truncate. 
Sikkim; in the valley of the Teesta, elevation 1,009 feet; Pantling No. 455; 
flowering in June. | 
The nearest ally of this is M. saprophyta, but this is in every way а larger 
plant; the tuber is elongated, not orbicular, the dorsal sepal is erect, not reflexed and 
not adpressed to the ovary; the lip in this is more pointed than in M. saprophyta, 
and it has no convex fold on its upper surface as in that species,

Stem 4 to 10 in. long, thickened near the base, tufted. Leaves three to six, elliptic- 
lanceolate, oblique, acute or acuminate, the base narrowed and sheathing, sessile or 
shortly petiolate, 7-nerved, the edges undulate; length of blade 3 to 12 in., breadth 
‘75 to 4'5 in. Inflorescence 6 to 14 in. long; the peduncle striate, with a few scattered 
subulate reflexed bracts "5 in. long; floral bract lanceolate, acuminate, nearly as long 
as or exceeding the undulately-winged stalked ovary. Flowers "95 in. long, resupinate, 
red or yellow, much crowded, Sepals oblong, sub-obtuse, the lateral pair faleate, Petals 
linear, obtuse. Lip rather fleshy, oblong, concave, scarcely exceeding the lateral 
sepals in length; its basal part without lobes; its anterior part 3-lobed, having two 
elongated, narrow, lateral lobes connected close to the column by a flat transverse 
callus, their free anterior extremities blunt; the apical lobe short, narrowly ovate,

This species has a very different lip from any other Microsty lis described in the 
present work; the basal lobes, so prominent in the others, being in this. entirely absent. 
There are moreover two transverse calli on the lip,—one at the base just beneath the
