Cauirorntan ANNUALS—Beauti- 
ful annual plants, mostly sent home 
hia, on the northwest coast of North 
America. They all bear cold much 
better than they do heat; and they 
will live through the British winters 
in the open air, without any protec- 
tion, though they are easily killed 
by the heat of summer, okie e 
if their roots become by any chance 
exposed to the full rays of the sun. 
The roots are indeed very feeble, 
particularly at the collar, where 
most plants are strong; and they 
will die in a few hours if the sun} 
strikes this vital part. Nature has 
provided against this danger, by 
giving most of these plants a trail- 
ing habit, and thus covering the 
roots with abundance of leaves ‘and 
stems; but cultivators, not being 
aware of the use of this, often, by 
training their plants over a frame, 
&c., expose the collar, and thus kill 
their plants. For the mode of sow- 
ing, &c., see ANNUALS. 
Ca'Ltua.—See Arum. 
Caxui'curoa. — Compédsite.— C. 
plaiyglossa, the only species known, 
is a showy Callipinian annual, with 
golden yellow flowers, requiring the 
usual treatment of Californian an- 
nuals. 
Cau.io'psis.— Compdésite.—Eve- 
one knows the beautiful plants 
which compose this genus under 
their old name of Coreepsis; from 
which genus they have been sepa- 
rated on account of a slight differ- 
ence in the internal structure of the 
flower. The new and old names 
have some resemblance in point 
of sound, but they are very different 
in origin, for Coreopsis is derived 
by Douglas, and natives of Califor-

mblance of the seeds 
while Calliopsis is 
ignily ing most bean- 
tiful. ‘The species are Soe an- 
nuals and perennials; the former 
of which may be sown in autumn, 
as they will cia! the winter with- 
out any protection, and will thus 
come into flower early in summer. 
All the species will grow in any 
common soil; and the perennial 
kinds are propagated by division of 
the root. Callidpsis bicolor is the 
same as Coredpsis tinctoria. 
Cauisrx'MaA.—One of the botanic 
names for the China Aster.—See 
| CALLISTE‘PAUS, 
Cauurste\mon.— Myrticee—Aus- 
tralian shrubs, with evergreen leaves 
and tassel-like fowers, better known 
by their old name of Metrosideros 
They should be grown in sandy 
loam; and cuttings of the old wood 
strike freely in sand under a bell- 
glass. 
CaxuistE‘pnus, Dee.—Compésite. 
—The China Aster, which some bot- 
anists now call by this name, is one 
of the most ornamental annuals in 
British gardens. There are many 
varieties, and those known as the 
German Asters are considered the 
most beautiful. They should be 
raised on a hotbed, in February or 
March, pricked out when the plants 
have two or three leaves, anditrans- 
planted into the open garden in 
May, where they will make a very 
fine appearance in September and 
October. They should be grown in 
light rich soil, or in loam and thor- 
oughly rotten dung. 
Catuu'na, D. Don.—The common 
Heather or Ling—See Ent‘ca. 
CaLocuo’rtus. — Tulipdcee. — 
Californian bulbs with splendid flow- 
ers, but rather difficult of culture. 
They require a very sandy soil, 
which should be covered with litter 
in frosty weather, if the bulbs are 
not taken up as soon as they have
