Sikkim, at elevations of from 4,000 to 6,000 feet, very abundant; in flower from 
October to January; Pantling, No. 26. Distributed westwards to Nepal and eastwards 
and southwards to the Naga, Khasia and Burmese hill ranges. 
In Sikkim this species forms large masses, often breaking down thick branches of 
trees by their weight. The flowers are white, there being, however, a patch of 
brown on the sac of the lip and the column being altogether brown, as is the rachis.

Pendulous; internodes of the stem cylindric or fusiform, 1 to 3 in. long, somewhat 
shrunken at flowering time, often clothed with fibrous sheaths. Leaves shortly petioled, 
linear-oblong, acuminate, slightly narrowed to the base, 4 to 6 in. long and °4 to “5 in. 
broad. Racemes about as long as the leaves while in flower but much longer when in 
fruit; the peduncle only about 1 in. long, enclosed in imbricated sheaths. Flowers *6 in. 
long; the огай bract scarious, narrow, oblong, subtruncate, with incurved edges, longer 
than the stalked ovary. Sepals sub-equal, free, narrowly oblong, obtuse, spreading. Petals 
slightly smaller than the sepals, oblanceolate, spreading. Zip with a short saccate 
bi-cornute base and a long oblong acute deflexed concave terminal lobe rather shorter 
than the sepals. Column short and with no foot, slightly winged towards the apex.

| 'The rachis, column, ovary and fruit are brown in colour; the saccate base of the lip 
brown with а tinge of pink; while the sepals, petals and anterior lobe of the lip are 
pure white. Ав in 0. porrecta and 0. alba, there is a fibrous core running through 
the superposed pseudo-bulbs which compose the stem.
