A very singular form of Dendrobium, one of asmall group 
which inhabits the Malayan Peninsula and Islands. Its 
nearest ally is the D. wnijflorum, Griff. (Notul. vol. iii. p. 305, 
and Ic. Pl. Asiat. t. 303), which differs in the much broader 
Sepals, petals, and lip, and is a native of Mount Ophir, 
Malacca. This or D. wniflorum may further prove to be 
the same as one of two plants from Penang, distributed by 
Wallich under his number 2002, with the name of D. 
bifariwm, Lindl., and which consist respectively of a 
Dendrobium without flower or fruit, but with axillary bracts, 
as in D. uniflorum and revolutum, and another plant with 
terminal and axillary short racemes, which Lindley subse- 
quently rightly identified with a Hong-Kong one, and which 
is his Appendicula bifaria (Kew Journ. Bot. vol. vii. p. 35). 
D. revolutum is a native of Singapore, whence it was first 
introduced into England nearly fifty years ago by the 
veteran collector Cuming, and cultivated by the Messrs. 
Loddiges. The specimen here figured was received from 
C. Peche, Esq., of Moulmein, in 1882, along with other 
orchids. The original Singapore specimen preserved in 
AUGUST Ist, 1883.
