_~CLEOME. 
The violet-flowered species, C. cerulea, was in- 
troduced from Japan in 1836. It is a hardy 
deciduous climber, and a most charming addition 
to the climbers cultivated in Britain. It has a 
most graceful habit of growth; and its large 
violet flowers, with deep purple stamens, are 
more beautiful than those of any of the previously 
introduced species. Its stem is slender, hairy, 
and usually about 12 feet high; its leaves are 
alternate, bright green above, very shining be- 
low, standing on long footstalks, and ternately 
or pinnately divided; its folioles are ovate or 
ovate-lanceolate, pointed, entire yet marginately 
wavy, and stand on long partial footstalks ; and 
its flowers are of a most delicate blue colour, 
and nearly seven inches in diameter, and appear 
in April. 
CLEOME. A genus of ornamental plants of 
the caper-tree tribe. A number of species for- 
merly included in it are now assigned to six other 
genera; but upwards of twenty species still be- 
longing to it are cultivated in British gardens, 
and between 30 and 40 other species have been 
scientifically described. Most of the species have 
sometimes been called bastard-mustard, and may 
be regarded as, in a loose and general manner, 
described by that name. One or two which grow 
wild in India, are there called dog-mustards, and 
esteemed somewhat anthelmintic and carmina- 
tive. The majority of the species in Britain are 
annuals; and a few of these, particularly C. penta- 
phylla, C. rosea, and C. spinosa, have a place in 
most tolerably good collections. Three species, 
C. arborea, C. dendroides, and C. gigantea, are ten- 
der evergreen shrubs, of from 5 to 9 feet in 
height. 
CLERCK’S MOTH, —scientifically Herzbeia 
clerckella. A lepidopterous insect, of the moth 
tribe. Its body is scarcely more than one-twelfth 
of an inch in length; but its wings are a quarter 
of an inch long,—the upper pair silvery, golden 
brown at the tip, somewhat streaked, and with 
a deep black, round eyelet at the extremities. 
It is an exceedingly beautiful little insect, and 
so very active that a living specimen of it cannot, 
without great difficulty, be obtained; but it is 
an old and increasing pest in gardens and or- 
chards, and inflicts material injury upon pear- 
trees. Its eggs seem to be deposited on the under 
surfaces of the leaves; and the caterpillars seem 
to penetrate the epidermis, and feed upon the 
parenchyma, Brown circular spots of about half 
an inch in diameter, and similar to such as might 
be occasioned by excess of heat, appear upon the 
leaves, and enclose the caterpillars ; and whenever 
these are numerous, the fruit is both small and 
ill-flavoured. 
CLERODENDRON. A genus of very beauti- 
ful, evergreen, tropical shrubs of the verbena 
tribe. About forty species have been introduced 
to Britain, all since 1784, and principally from 
India, China, and Nepaul; and two or three 
other species have been described. One of the 
CLICKING. 815 
introduced species is a twiner; and the others are 
erect shrubs of from 3 to 10 feet in height. All 
are handsome and some are superb; and if brought 
into flower in the stove, and gradually attem- 
pered to the greenhouse, they will bloom during 
three months in the latter, at a season when 
little else of prime character can be had to 
decorate it. A mistake prevails, and ought to 
be dissipated, that clerodendrons will show good 
bloom only in heat so intense as to be intolerable 
by an European. We shall illustrate the genus 
by a brief notice of three of its species. 
The unfortunate species, C. infortunatum, was 
introduced since 1840 from Ceylon. Its stem 
is quadrangular, and about six feet high; its 
leaves are heart-shaped and large; its flowers 
have a deep crimson colour,—are formed of five 
unequally spreading portions, similar to those of 
the common garden azaleas, with long protruding 
coloured stamens or thread-like appendages,— 
and are produced, in spreading panicles, on the 
summits of the shoots—The glandular-bracted 
species, C. glandulosum, is a plant of exceedingly 
noble and magnificent appearance. Its leaves 
are large, and oval, and seem as if bitten off at 
the base; and its flowers have a scarlet colour, 
grow in heads, and are surrounded by long, nar- 
row, permanent bracts.—The deceitful species, 
C. fallax, was brought from China in 1790. Its 
leaves are large, roundish, heart-shaped, and 
toothed; its flowers have a scarlet colour, and 
are intermediate in size between those of the 
unfortunate and the glandular-bracted species; 
and its calyxes, instead of being divided through 
half their length into five segments, are provided 
with five short teeth—Many of the other species 
have white and whitish-red flowers. The phlo- 
mis-like species is used medicinally in India as an 
alterative. Glory-tree has been proposed as the 
popular name of the clerodendrons; but it has 
not yet become well established. ; 
CLETCH. A brood of chickens, goslings, or 
other birds. 
CLETHRA. A genus of white-flowered shrubs 
and small trees, of the heath tribe. The alder- 
leaved species, or American alder, C. alnifolia, 
was brought from North America in 1731. It is 
a hardy deciduous shrub, of 4 or 5 feet high 
with us, and 8 or 10 feet in its native country. 
Its branches are not numerous; its leaves are 
spear-shaped, serrated, about three inches long 
and an inch and a half broad; and its flowers 
are fragrant, grow in long spikes at the ends of 
the branches, and bloom from July till October. 
—Six other deciduous species, and two evergreen 
species, have been introduced; but the ever- 
greens are tall and tender.
