“I am very happy in dedicating this very distinct species 
to my valued friend Capt. Jenkins, to whom this garden, the 
cause of botany, and science generally, are deeply indebted. 
“The flowers are larger than those of D. aggregatum of 
Roxburgh, to which it bears a slight resemblance.” 
The species shews in a striking manner the impropriety 
of generically separating the pseudo-bulbous Dendrobia from 
those with slender stems, notwithstanding the dissimilarity 
in their appearance. Here we have a plant with the pseudo- 
bulbs consisting, in the majority of instances, of a single 
internode, hardened, become four-cornered, and as dissimilar 
as possible from the same part of the stem of Dendrobium 
Pierardi; but in D. aggregatum, figured in this work, 
t. 1695, several internodes (3) together constitute a body 
altogether intermediate in nature between a pseudo-bulb 
and ordinary stem, and similar transitions from one to the 
other occur in D. densiflorum, fol. 1828, and D.Griffithianum, 
all which are so nearly allied to each other that a person 
unacquainted with all of them may possibly mistake one 
for the other. To prevent this the following distinctions in 
the labellum will be found certain. 
D. Jenkinsi.  Labellum broader than long, repand, 
slightly two-lobed, shaggy, serrated: 
D. aggregatum. Labellum broader than long, scarcely 
wavy, undivided, downy only near the base. 
D. densiflorum. Labellum cordate, repand, two-lobed, 
reflexed at the point, serrated. 
D. Griffithianum. — Labellum ovate, slightly hastate, 
serrated, downy, except near the edges. 
This species is more difficult to cultivate than those 
kinds with long free-growing stems. It is frequently seen 
in an unhealthy state, owing to its being grown in a pot, 
and subjected to a uniform high degree of temperature. 
The best way to insure its success, is, to tie it to a block of 
wood with a piece of turfy peat attached to it, and suspend 
it from the rafter of the house. There it must be well 
syringed at least twice a day, so long as it continues to grow, 
and afterwards it may be removed to a cooler house. In 
fact it never requires so much heat as those species with 
long trailing stems. 
It is propagated in the usual way.
