It is said to grow as far north as "the dry gravelly islands and bars of the Wahlamut river above the falls," 
in Oregon; but it is best known from more southern regions, Hartweg's discovery of it in California having been 
anticipated by the naturalists with Captain Beechy, and by Dr. Coulter, of whose dried plants it is No. 110. In our 
gardens it betrays a tender climate, for it is much more impatient of cold than the other Californian species, than which 
it is far less attractive, its scanty white flowers producing a shabby appearance, for which the leaves and scrubby 
aspect of the species do not compensate. — journal of Horticultural Society^ vol. vi.

This very fine plant was received from Assam in February last, by Thomas Denne, Esq., of Hythe in Kent, and 
flowered with him in May. The stems are terete, from eighteen hiches to two feet long ; the leaves we have not seen. 
The flowers appear in fives, in close heads, from among some hard scales ; and are separated by large membranous 
bracts almost as in D, dermjlorum ; when the racemes are full grown their rachis is zigzag, and the broad membranous 
bracts are full as long as the joints of the rachis. The expanded flowers are about two inches across when flattened, but 
as the parts spread but little from the column they appear smaller ; they are of a rich orange-yellow, with a broad 
double brown blotch in the middle of the lip. The sepals are much narrower than the petals, which are not at all 
fnnged. The lip, when flattened, is broader than long, slightly three-lobed, round, hairy over all the upper surface, and 
strongly ciliated, though not fringed, at the edge. Mr. Denne most truly says, that « It is certainly the handsomest of 
ttie orange Dendrobes, being superior to D. Paxtoni in size and texture and also in the markings of the lip, thou<rh it 
has not the fimbriated edge." The affinity of this species is with B. fimhnatum and moschatum, to the latter of which we 
were formerly led by bad specimens to refer it as a synonyme. From D, Jimhrlatum it differs in having large membranous 
bracts, and no deep fringes to the hp. In its bracts it agrees with I). moscJiatum, and in the flowers appearing from 
withm hard scales, but the lip has not the inflexed edge and slipper-like form of that species, and the racemes are much 
shorter.
