which must be very rarely produced.

A common little plant in mangrove swamps, orchards, and 
open country. The plain yellow form and the one veined with 
red occur mixed. It generally grows on trees low down. In 
Sungei Ujong it is called “ Sakat Kalumbat,” and the roots are 
boiled and applied in cases of dropsy. D. carnosum, Teysm. 
et Binn. in Tijdschr. Nederl. Ind., v. (1853) p. 489, seems to 
be intended for this species. 
The section, § Desmotrichum, includes the species given 
under Cadetia in the Flora of British India, but not the Cadetias 
of Blume and Gaudichand, which form, as it seems to me, 
very distinct section of themselves. The name was originally 
given by Blume to a number of species of Dendrobium, most of 
which I would retain in this section, while others evidently 
belong to the Sarcopodium section. In Desmotrichuwm the 
primary stem is sometimes elongate and creeping, and some- 
times short, but in any case it throws up many slender 
polynodal stems, which branch again and again, and each 
branch is terminated by a pseudo-bulb composed of one, rarely 
two, internodes: one, the lower, very large and dilate; the 
other, when present, very short. The lower one bears a broad, 
more rarely narrow, somewhat coriaceous leaf, from the axil of 
which are emitted one or two inflorescences. These are 
racemose, but, as a rule, only one flower is produced at a time. 
The two inflorescences are not synchronous, but develop one 
after the other at considerable intervals of time. They are 
enclosed at the base by two bracts, dry and cartilaginous, 
which eventually break up before flowering into fibrils. In
