Many years since an Orchideous Epiphyte was sent from Chitta- 
gong with some other species to the Botanical Garden, Calcutta, 
when Dr. Roxburgh named one of them Dendrobium Pierardi, in 
compliment to the gentleman who discovered it. In his Flora Indica 
Dr. Roxburgh adds that it is also a native of various parts of the 
Delta of the Ganges, where it is generally found on Mangoe Trees. 
No one has however been able to discover any plant which answers 
exactly to Dr. Roxburgh’s description of his D. Pierardi; and what 
is now cultivated under that name in the Calcutta Garden appears 
from Dr. Wallich’s specimens to be the plant defined by Dr. a 
in the seventh volume of the first series of this work under the name 
of D. cucullatum. 
When the first part of the Genera and Species of Orchideous Plants 
was published, we had satisfied ourselves that in all probability Dr. 
Roxburgh had confounded two or three different species under the 
common name of D. Pierardi; and accordingly we took the species 
represented by Dr. Hooker in his Exotic Flora, as the authority for 
the name, and we considered Dr. Brown’s Dendrobium cucullatum, 
to be a mere form of it. 
We have since had an opportunity of comparing D. Pierardi and 
cucullatum side by side, in the utmost perfection in the stove of the 
Messrs. Loddiges, where these lovely species flowered in great imd 
dour in January last, forming festoons two or three feet long, 
Tu covered with the most delicate pink and yellow blossoms. At 
rst sight they are so entirely the same that one does not immediately 
pereeive in what their differences consist; but upon a more attentive 
inspection it is found that D. cucullutum has larger flowers, with a 
broad roundish-ovate lip, the base of whieh is rolled up into a sort 
of short stalk, while in D. Pierardi the lip is rounded and very 
blunt, and its base is rolled into a much longer stalk, which quite 
conceals the column; it is moreover remarkably incurved. These
