DENDROBIUM DENSIFLORUM. 
they so profusely inhabit. The extensive and truly valuable genus, to which the 
subject of pur present notice belongs, should especially be subjected to a change 
of treatment assimilating as much as possible to that above-mentioned, for without 
this, they will seldom flower at all, and never in perfection. 
All, or the greater number of the species of Dendrobium, flower in India in the 
hot or dry season, which is succeeded by the rainy season, when they make their 
shoots, and during the cold or winter season, they have a period of repose ; they 
thus enjoy three seasons, while in this country we have four, the autumnal quarter 
not being known there. The different seasons of India being thus so well known, 
it is by no means difficult to imitate them in our hothouses, and, by attending to 
these simple rules, we should be enabled to flower the various species of Den- 
drobium, more abundantly than those of any other genus of Orchidaceae ; besides 
which, we might easily induce them to flower in this country at any season of 
the year. 
This species may be propagated by detaching one of the stems, while in a 
dormant state, taking care not to injure the roots, and potting it carefully into 
heath soil, well drained ; the stem will require supporting with a slender stake, 
and the pot containing it should be plunged in a gentle bottom heat, where it 
will speedily produce new shoots.
