58 ORCHIDS OF THE SIKKIM-HIMALAYA. 
Dendrob. 67. True D. palpebrae is a smaller plant than D. Farmeri, with thinner less 
clavate 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 of the lip; the 
sides of the lip are also much ciliate (hence the specific name); the petals are slightly 
narrower and more acute than those of D. Farmeri. The colour of the sepals and petals 
of D, palpebrae is white, and that of the lip yellow. 
There is, however, a form of D. Farmeri in Burma 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 ZD. chrysotorum. To this the varietal name aureo;f/ava 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 parviflora. The synonymy 
of these stands thus:— 
Var. parviflora, Regel, Garten-flora XXII, 67; D. Furmeri, Bot. Mag., t. 4659; 
flowers smaller than iu the type; originally sent to England by Dr. McLelland from 
the Bot. Gard., Caleutta, and almost certainly a native of Burmah. 
Var. aureo-flava, Hook. fil. Bot. Mag., t. 5451; whole flower yellow; from Burmah.
