of the spurred sepal and spur. Strachey and Winterbottom’s specimen 
has much shorter peduncles than the Sikkim ones.

This is a very puzzling plant: Wallich's characters do not well agree 
with those of his no. 4768 in Herb. Henslow as to the leaves, which are 
shorter and broader than the description indicates. The flowers of the 
Nepal plant are yellow, but in the Sikkim varieties lilac, white, or purple. 
The leaves vary in size from 2-6 inches, and the peduncles, which are 
axillary and terminal vary quite as much; generally they are very 
slender, patent, and filiform, but in var. у often stout and erect, with 
large persistent subulate bracts. I find four lateral sepals in var. y, of 
which the two accessory are often reduced to hairs. The spur is some- 
times wholly absent in Sikkim specimens. The much greater size of the 
flowers, and their broad spurred labellum, sepal, and broad petals di- 
stinguish this from I. longipes, which is its nearest ally.
