flowered in the lower two-thirds, laxly-flowered in the upper third; foral bracts equal- 
ling and sheathing the stout sessile ovary, oblong, sub-entire. Flowers warm brown, 
minute, ‘05 in. long, whorled.  Sepais oblong, blunt, entire, revolute. Petals narrowly 
elliptic, sub-acute, coarsely and unequally serrate, spreading. Гір not таса longer 
than the sepals, elliptic-lanceolate, blunt, not distinctly lobed but everywhere irregular- 
ly lobulate-erose; the base truncate and with a circular nectar-bearing pit just under 
the column. Pollinia orange-coloured. 
At the mouth of the Teesta valley near Sivoke, elevation about 1,000 feet; Pantling 
No. 225; only once collected; in flower during April and May. Distrib.—Perak ; 
Scortechini, No. 582. sd 
A singularly beautiful little species with charming warm-brown flowers. 16 is 
evidently a straggler northwards of the Malayan Flora, only a single specimen of it 
having as yet been eollected in British India, and that at а spot on the outer flank of 
the Himalaya. Father Scortechini, who collected for several years in Perak, has left 
an excellent pencil drawing of the Perak plant, which, as well as his manuscript 
description, agrees with the Sikkim plant. This is closely allied to О. Bertoldi, King and 
Pantling, another species of which Father Scortechini collected specimens in Perak, and 
of which he left a drawing now in the Calcutta Herbarium.
