Wight, in describing Dendrobium Jerdonianum, gives 
two habitats for it, namely, Coorg jungles, Jerdon, and 
Iyamally Hills (which are in the Nilgherry district), adding 
that “the specimens from the two stations differ in the 
size of the flowers, but in both they are spurred, and have 
the same long narrow form, and agree in colour, hence I 
consider them mere varieties.” Of these two forms, that 
figured by Wight is the smaller flowered, with a spur-like 
mentum half as long as the sepals, and is, I think, identical | 
with the Cingalese D. nutans, for a good figure of which 
_ see Annals of the Royal Botanic Gardens of Calcutta,” 
vol. xii. t.18. The other, with the larger flowers and very 
short mentum, here figured, is the Coorg plant of Jerdon, 
as proved by a sketch of the flower made by that naturalist 
which is preserved in the Kew Herbarium. 
D, Jerdonianum was introduced into England previous 
to 1852, when it was described by Lindley (in Paxton’s 
“Flower Garden,” as D. villosulum) from a plant sent 
OcroBer Ist, 1900.
