160 ORCHIDS OF THE SIKKIM-HIMALAYA. 
as long as the stalked ovary. Sepals sub-equal, ovate, sub-acute, apiculate, strongly 
recurved (especially the lateral pair). Petals about as long as the sepals but much 
narrower, wide-spreading, lanceolate, blunt; the basal half dilated, membranous and with 
fimbriate edges; the apical half narrow, fleshy. Zip as long as the sepals, with a 
broadly orbicular cochleate base with narrow erect rounded erose side lobes and a 
fleshy tongue-like entire blunt apical lobe. Column very short. Anther with a fleshy 
cap containing two distant cells. Pollinia 4, ovoid, in two pairs, each pair lying remote 
from the other, attached to its own caudicle, and resting on its own short rostellum 
overhanging the stigma; the candicles flattened, dilated upwards, each ending below in 
an ovate gland. Stigma large, transversely oblong, occupying the whole breadth of the 
column in its upper half. 
Bhutan, near Buxa, at an elevation of about 6,000 feet; Anderson; Pantling's 
drawing No. 473. 
The sepals and petals of this most interesting little plant are yellowish, and the 
lip is purple. Plants of it were collected above Buxa, in Bhutan, by Dr. A. R. S. 
Anderson, Surgeon-Naturalist to Н. M. S. Investigator, and Officiating Superintendent of 
the India Museum, Calcutta. It has not as yet been found in Sikkim. It is, however, 
so small that it may easily enough have escaped observation in the latter province. 
We make no apology, however, for introducing it here, as it affords an excellent 
example of an Jone with unmistakeable glands to the caudicles of its pollinia, and 
thus strengthens the arguments for the inclusion of this genus in the tribe Vandeae. 
In this, as in other three of the five species here described, the pollen masses rest 
on the caudicles and are not attached to them by granular elastic threads as 
directly in the majority of typical Vandeae; but in I. seariosa such threads are present. 
The plant here figured, having been sent by Dr. Anderson, flowered at the Govern- 
ment Cinchona Plantation at Mungpoo in Sikkim in April 1897; and the drawing here 
reproduced was made there by Mr. Pantling.

Rhizome less than *1 in. thick, naked; pseudo-bulbs ovoid, semi-transparent, *5 in. 
long, less than “1 in. apart. Leaf linear, notched at the apex, slightly narrowed to 
the sessile base, 2 to 4 in. long, and :2 to :25 in. broad. Scape only slightly longer 
than the pseudo-bulb, zig-zagged, enveloped at the base by two or three sheaths and 
bearing one or two flowers; floral bract lanceolate, equal to or longer than the shortly- 
stalked ovary. Flowers “5 in. across, pale green. Sepals spreading, sub-equal, lanceolate, 
the lateral pair lying under the lip and coherent by their tips. Petals about half as long 
as the sepals, spreading, more or less twisted, linear, with dilated more or less denti- 
culate concave bases. Lip slightly shorter than the sepals, lanceolate, with a dilated 
concave slightly auriculate base, and much elongate caudate-acuminate apex; the base 
with a very broad truncate claw attaching it to the very short foot of the column. 
Column short, Lroad, narrowly winged at the middle; rosiellum broad, deflexed ; pollinia
