Callirhoe— continued. 
Malvaceœ. A genus of elegant annual or perennial herbs, 
natives of North America. They are of extremely easy 
cultivation,sthriving in a compost of light, rich, sandy loam. 
Propagation of the perennial species may be effected by 
means of both seeds and cuttings; of the annuals, by 
seeds only. Seeds should be.sown in spring, either out- 
side, or in pans ina cold frame. Young cuttings should be 
taken and dibbled in sandy soil in a frame. 
C. digitata (fingered).* jl, reddish-purple ; peduncles long, axillary, 
one-flowered. Summer, l. sub-peltate, six to seven-parted, with 
linear-entire or two-parted segments ; upper one§ more simple. 
h. 2ft. to 3ft. 1824. Perennial. (S. B. F. G. 129, under the name 
of Nuttallia digitata.) 
C. involucrata (involucrate),* fl. crimson, nearly 2in. across, 
loosely panicled. Summer. J. divided nearly to the base, three 
to five-parted ; segments narrow, lanceolate, three to five-toothed, 
hairy on both surfaces. Habit procumbent; stems hairy. h. 6in. 
Perennial. (G. W. P. A, 26.) SYN, Malva involucrata (B. M. 4681). 
C. Papaver (Poppy-like).* fl. violet-red; sepals ovate-acute, 
ciliated. Summer, l., root leaves lobed or pedate ; lower stem 
leaves palmato-pedate, upper digitate or simple. A, 3ft. Louisiana, 
1833. Perennial. SYN. Nuttallia Papaver. (B. M. 3287.)

CALLISTEMON (from kallos, beanty, and stemon, 
a stamen; in most of the species, the stamens are of a 
YV beautiful scarlet colour). ORD. 
N | VA Myrtacee. Handsome greenhouse 
=M evergreen shrubs or trees, having 
AT the inflorescence rising from the 
old branches in crowded spikes, as 
in the species of Melaleuca, but 
with the stamens free, as in Me- 
trosideros. Leaves elongated, stiff, 
alternate, usually lanceolate. All 
the species of this genus are very 
ornamental and neat in habit. 
They are well adapted for a con- 
servatory. The soil best suited 
for them is a mixture of loam, 
peat, and sand. Ripened cuttings 
strike root in sand, under a hand 
glass; seeds are frequently pro- 
duced on large plants, and these 
may also be used to increase the 
stock, but they do not produce 
flowering plants for a considerable 
time; whereas plants raised from 
cuttings, taken from flowering 
plants, come, into flower when 
small. -

bescence. June. l. linear, stiff, acute, 
keeled beneath, channelled above, vil-

ends, mucronate, one-nerved, villous 
when young, as’ well as the branches.
