in. And in case of more than usually severe frost setting in, it may be very advis- 
able to spread over the roots and around the “ collar” of the plants, the top-dressing 
already referred to ; leaf-mould is also an excellent material for this purpose, and is 
a more efficient covering if little more than half decayed only. 
R. Barclay ana, as subjected to a general course of treatment, may be dealt with 
similarly to the more common species, but possibly is less hardy. 
In first forming beds of the China Roses, a considerable quantity of plants will 
be required, and at all times a good number should be reserved in pots, that casual- 
ties may at all times he provided against. They are easily propagated by cuttings, 
at any period, hut those taken in August and placed in a mixture of peat, silver sand, 
and leaf-mould, under a hand-glass, in a shady situation, will strike very readily, 
and by the beginning of October be fit to take up and be potted ; plunging them in 
l coal-aslies or similar material, in a cold frame, and there effectually screening them 
from frost till spring, when, as early as possible, they should be planted out. 
As we have already stated, the Chinese Roses, planted in masses, in the absence 
of other kinds in summer, form a splendid and exhilarating addition to the beauties 
. of the flower garden.

NEW OR BEAUTIFUL PLANTS FIGURED IN THE LEADING BOTANICAL PERIODICALS 
FOR DECEMBER, JANUARY, AND FEBRUARY. 
Abe'lia rupe'stris is a small, spreading, slender-branched busk, with bright-green, ovate, 
serrated, opposite leaves, and pure white, sweet-scented flowers, which are produced in a manner 
similar to those of the Honeysuckle. At present it has been treated as a greenhouse plant, as 
which it is valuable from remaining a long time in flower ; but it is expected to be sufficiently 
hardy to endure mild winters in the open air. Mr. Fortune forwarded it to this country in 
1844, from the Chamoo Hills in China, where he found it growing among rocks. Bot. Reg., 8. 
Adenocalym'na como'sum was sent to the Royal Gardens of Kew, from Rio, in 1841, by 
J. Lynd, Esq. It is a truly fine stove climber, having opposite, ovate, sometimes rather lanceolate 
leaves, and bearing racemes of “ large, handsome, bright-yellow, trumpet-shaped ” flowers. The 
racemes are borne “both axillary and terminal, at first so densely clothed with large concave brac- 
teas as to look like the large aments of the Hop ; these fall away before the corollas expand, 
except two lesser bracts upon each pedicel, but which still are larger than the calyx, and even- 
tually fall away also.” The stems are covered with brown spots, and “the leaves, bracts, and 
calyces beset with conspicuous pateriform dark-coloured glands,” from the Greek designation of 
which the generic name is derived. De Candolle considers the A. longibracteatum scarcely to be 
distinct from this species. Bot. Mag., 4210. 
Dendro'bium Dalhousiea'num. “None of the species,” writes Dr. Lindley, “exceed it in 
beauty, for, with the large flowers and noble aspect of the c Musk ’ Dendrobium, it is enriched by 
two large blood-red spots on each side of the lip, which melt into a row of fringes turned towards 
the middle, and looking like a pair of young whiskers fresh from the curling irons of the hair- 
dresser.” Bot. Reg., 10. (A figure of this species is given in Yol. xi. of this work.) 
FrancTscea Hydrangejsfor'mis. This fine plant was discovered byPolil at Olaria, near Rio 
Parahybuna, in 1818. Mr. Gardner found it in the Organ Mountains in 1837. He, states Sir 
W. J. Hooker, writing from Rio, upon a label attached to specimens of it, describes it as a shrub 
about four feet high, growing in rather moist places in virgin forests, and attaining an elevation
