6 2 OR C H I D S OP THE SIEKIM-HIMALAYA.
Sikkim; common in tropical valleys; in flower during May; Pantling No. 266.
Khasia Hills, Upper Burmah, Java; the Nilgiri Eills and Western Ghiits in Southern
I n d i a ; also in Ceylon.
The difficulty of understanding the structure of the lip from an examination of
dried specimens no doubt in part accounts for the number of names which have
been given to this species. The foregoing synonymy has, with the exception of
D. pUoatiie, been taken verbatim from Sir Joseph Hooker's "Flora of British India";
and for the latter synonym we are also indebted to Sir Joseph. The flowers of this are
white, the side lobes of the lip and the column being piuk with purple spots; the apex
of the Up is pale green.

The flowers are of a pale chestiiut brown. The rhizomes are pendent. Its nearest
a l ly is D. ficseescens, Lindl., from which this differs in having broader leaves and
niuch shorter pedicellate ovaries, broader petals, and a lip with a smaller anterior
lobe.
