58 ORCHIDS OP THE SIKElM-HIMiLiTA.
Dendi'ob. 67. Truo D. palpebrae is a smaller plant tliau D. Farmon, with thinner less
clavatc stems. In it the lip is trowel-shaped and there is an elongated callus, 2-lobed
and ciliate at the base, which runs along the centre of the lower half o£ the lip; the
sides of tlie hp are also much ciliate (hence the specific name); tho petals arc slightly
naiTOwer and more acute than those of D. Farmeri. The colour of the sepals and petals
of D. paljyehrae is- white, and that of the lip yellow.
There is, however, a form of D. Farmeri in Bui-ma in which the sepals and petals,
as well as the lip, are always yellow, and which was considered on its first discovery
to be closely allied to D. ckrysotozum. To this the varietal name aureo-Jlava has been
given. There is also in Burmah a form with smaller flowers than those of typical
D. Farmeri, and to this Regel has given the varietal name parvijlora. Tho synonymy
of these stands thus:—
Var. parviflora, Kegel, Gaiten-flora XXIII, 67; D. Farmeri, Bot. Mag., t. 4659;
flowers smaller than in the type; originally sent to England by Dr. McLclland from
the Bot. Gard., Calcutta, and almost certainly a native of Burmali.

Sikkim; in tropical valleys ascending to 4,500 feet; common; Pantling No. 360.
Westward to Kamaon and eastward to Bhotan, the Assam and Khasia Hills, and to
Chittagong and Upper Burmah; also in Peralc. In flower from ilarch to May.
The flowers are of a brilliant yellow colour, and in this variety {ocitlaia) there
is a large orbicular patch of rich reddish-brown on the lip. The flower in tbe typical
form has no such spot and must be therefore much less handsome. It does not occur
in Sikkim. We have never seen a specimen of it living or dead, and arc inclined to
doubt its occmTence io the Eastern
