Dendrobium, notwithstanding the peculiar habit, which is 
something like that of Bolbophyllum. : 
A careful examination of such species as have come 
beneath our observation within the last few years has equally 
failed to satisfy us of the distinctness of the genus. In fact, 
there is but one character deserving of notice that we are 
able to point out, and that is the presence of two or three 
raised ridges or plates upon the axis of the lip. Such plates 
or ridges occur conspicuously in the present species and in 
D. angulatum, criniferum, Scopa, longicolle, amplum, and 
some others, which would therefore be thus sufficiently well 
characterized. But there are no plates or ridges in D. aggre- 
gatum or Jenkinsii, which haye the habit of the genus, to 
say nothing of D. braccatum, muscicola, and extinctorium, 
which require re-examination, Further consideration, and 
a more extensive knowledge of species are necessary in order 
to settle this point. : 
Fig. 1. represents the column of this plant, and fig. 2. the 
lip spread flat and magnified. 
The species may either be potted in turfy peat, in the 
usual way, or it may be tied to a block of wood, and sus- 
pended to a rafter, Like many other Orchids it requires a 
good deal of water during summer, and a slight shade in 
sunny weather. In winter, for a few weeks, no more water 
should be given than keeps the stems from shriveling. The 
temperature most congenial to tbis plant, is little more than 
that of a common greenhouse.
