to 6 in, long and 1 to 2 in. broad; petiole about '25 in. long. Flowers 1 in. in 
diameter, solitary or two or three from the base of a pseudo-bulb; pedicel and ovary 
about as long as the pseudo-bulb; floral bract broad, sub-spathaceous, pale, ochraceous, 
spotted with purple. Sepals ovate-lanceolate, sub-acute, 9-nerved. Petals smaller than 
the sepals, 7-nerved. Zip shorter than the petals, thick, decurved from below the 
middle, lanceolate, the base with small toothed auricles near its attachment to the 
apex of the much-curved foot of the column; the apex obtuse, the upper surface 
concave and with an elongated nectar-secreting groove expanding at its base into a 
triangular pit. Anther conical. Walp. Ann. VI, 217; Hook. fil Fl. Br. Ind. V, 756.

. А handsome species not previously collected in Sikkim. The sepals and petals are 
whitish or pale-ochraceous, spotted with crimson; the lip is deep crimson or purple, 
indistinctly spotted, and the column yellow, which colour passes into purple in the 
mentum. The nectar, plentifully secreted by the lip, is of a pinkish colour and possesses 
an odour suggestive of decaying fruit, which is very attractive to flies of all kinds. Mr. 
Pantling has recorded the following incident, which throws some light on the fertilization 
of the genus generally :—“ One of the many visitors to the plant on my table while 
I was making & drawing of it was an insect rather longer than the common house- 
fly, but brownish in colour and clothed with stiff hairs. One of these alighted on a 
flower and depressed the mobile lip to its utmost. As the fly absorbed the nectar on 
the anterior part of the lip it gradually approached nearer and nearer the base, seeking 
for more, As it got to the part of the lip which bends down to join the column, the 
lip began to rise, and as the latter suddenly assumed its normal position, the fly was 
pressed between it and the column and was for some time held a prisoner. After 
some struggles, it managed to escape, carrying off one of the pollinia glued to its 
thorax. This incident may assist to throw some light on the use of the mobility of the 
lip so characteristic of this genus and of Cirrhopetalum."

Rhizome about 72 in. thick, very long, the apical (growing) part with spotted 
sheaths “5 in. long. Pseudo-bulbs about 6 or 7 in. apart, ovoid, smooth, with scarious sheaths
