is a little diminished even there; and in our culture, they are 
the better for being in the open air during the last part of 
summer, and the first of autumn ; because this makes them less 
tender than if they remained in the green-house all the year. 
If this exposure is continued just long enough for giving the 
plants a little consistency, but not so long as to suspend their 
action by driving it into the wood and buds, then they are in 
proper condition for obeying any stimulus, either for forcing, or 
for a fine natural bloom early in the season. But if it is carried 
too far, they lose their leaves, do not answer for forcing, and do 
not bloom so early or so rich. All of which shows that, though 
they can bear drought, neglect, and any degree of cold, above 
absolute frost, for a portion of the year ; yet, that their nature 
is essentially adapted to the ever-green districts of their native 
regions. It is this adaptation to two modes of treatment, 
together with their redolence of life in every joint, and the 
greater number being essentially one species, that have rendered 
these plants such obedient and plastic things under the hand of 
the skilful cultivator. There are few, if any, plants more easily 
propagated, either by cuttings or by seeds. The first is used 
chiefly to increase the number of an approved variety, and the 
last to obtain new varieties by cross impregnation. The vast 
success which has attended Pelargoniums should lead those who 
speculate in plants to try other soft-wooded shrubby ones which 
are natives of similar places.

16. Dendrobium Cambridgeanum .—The flowers are bright 
orange. This is a beautiful species ; the leaves are ovate and 
acuminate, alternate on the stem, or pseudo bulb ; the flowers 
come out opposite the leaves, two and three together; they arc 
very large ; the stems, or pseudo bulbs, are compressed and thick ; 
they do not grow to any great length, but this is a very distinct 
species. It is pendent, and thus does best in a basket ; requires 
a cool and dry rest; when growing, requires plenty of moisture 
and great heat. A native of the East Indies; introduced in 
1837.
