D. denudans (Don. Prodr. 34. Wall. Cat. no. 2014. 
L. no. 42); caulibus brevibus cespitosis erectis vaginis 
laxis foliorum vestitis, foliis oblongo-lanceolatis submem- 
branaceis apice obliquis emarginatis, racemis lateralibus 
terminalibusque nutantibus multifloris, sepalis acumi- 
natis: lateralibus basi incurvis, petalis minoribus, labelli 
trilobioblongi lobo medio acuminato crispo lateralibus ser- 
ratis, disco bilamellato.—-—— Nepal. —— Flowers greenish 
white, Lip green, whole-coloured. This species is the 
most variable that I know in point of size. Some of 
Dr. Wallich's specimens are not more than an inch and 
half high, with two or three leaves and as many flowers 
on each individual, while others are six or seven inches 
high, with numerous distichous leaves, and three or four 
- long nodding racemes, each consisting of eight or nine 
flowers. The species is always distinguishable by the 
loose membranous sheaths which clothe the stem when 
the leaves have fallen off. 
D. alpestre (Royle Illustr. t. 88. fig. 2); caulibus bre- 
vissimis ovatis 3-4-phyllis, foliis lineari-oblongis, racemis 
3-5-floris erectis, sepalis acuminatis cornu brevi obtuso, 
petalis minoribus, labelli trilobi lanceolati lobo medio 
acuminato crispo basi angustato lateralibus laceris, disco 
bilamellato. Himalayas.——— Stems and leaves only a 
few inches high. Flowers white, with a purplish lip. 
D. cuspidatum (Lindl. no. 43) ; caulibus brevibus erectis 
3-5-phyllis, foliis lineari-oblongis apice obliquis emar- 
ginatis, racemis terminalibus 3-4-floris foliis brevioribus, 
bracteis lineari-ovatis acutis, petalis sepalisque lineari- 
lanceolatis acuminatis equalibus: horum lateralibus basi 
incurvis cornu referentibus, labelli trilobi petalis dupló 
brevioris lobis lateralibus maximis erectis rotundatis in- 
tegerrimis : intermedio ovato acuminato. Tavoy.—— 
This resembles in many respects D. denudans, from 
which it is abundäntly distinguished by the loose sheaths 
of the fallen leaves not covering the stem, and by the 
peculiar form of the lip. My specimens are from three 
to four inches high. ‘The flowers appear to be white. 
62. D. microbolbon (Ach. Richard. Ann. Sc. n. s. 15. t. 8); 
caulibus parvis ovatis aggregatis diphyllis, foliis oblongo- 
linearibus. submembranaceis acutis, scapo gracili foliis 
longiori apice trifloro, racemo trifloro, petalis linearibus
