ORCHIDAC^. 
Generic Character. — See vol. iii., p. 77. 
Specific Character. — Stems jointed, swelling at tine joints, pendulous, leafy at the summit. Leaves 
oblong, acute, nervose. Racemes lateral, many-flowered, much longer than the leaves, conical.

The specimen of this beautiful species from which our figure was taken, was 
imported with numerous others by His Grace the Duke of Devonshire, from the 
Khoseea hills, where it was found by Mr. John Gibson, his Grace's collector, 
growing upon trees, in shady, moist woods, at an elevation of about three thousand 
feet. It is also, and more plentifully, found on the Nepal hills, from whence it 
was first sent to this country by the indefatigable Dr. Wallich. 
Plants of this showy species, when grown in the artificial climate of our hot- 
houses, seldom produce their flowers, which is chiefly owing to the inattention 
of cultivators to the process of drying them, and also of preventing them from flower- 
ing at their favourite season ; for, with due regard to these particulars, we have 
succeeded in flowering, most profusely, no less than six plants of this species in the 
collection at Chats worth. 
It is well known that Orchidaceae, like other plants, require a regular course of 
seasons to cultivate them successfully ; or in other words, they require a season of 
growth, a season of rest, and a season for flowering, all of which should coincide in 
order and duration with the corresponding seasons of those parts of the globe which
