CONYZA (from konis, dust; because it was supposed 
to have the power, when powdered and sprinkled, of 
driving away flies.  Fleabane. ORD. Composite. А 
rather extensive genus of stove, greenhouse, and hardy 
herbaceous plants, rarely shrubby. The involucre is cam- 
panulate, with from two to several series of linear or 
linear-lanceolate bracts; receptacle flat or convex, naked 
or foveolate; disk-florets yellow, those of the ray paler in 
colour. Leaves alternate, entire, toothed (rarely out). 
There are about fifty species, most of which are confined 
to tropical and sub-tropical regions of both hemispheres, 
They are mainly of botanical interest only, and do not 
call for further mention in this work. 
СООКТА (named after Captain James Cook, R.N., the 
celebrated circumnavigator, who was killed in the Sand- 
wich Islands in 1779). Wampee-tree. ORD. Rutacee. 
Small greenhouse trees. Leaves impari-pinnate; leaflets 
alternate, unequal at the base, or oblique. They thrive 
well in a mixture of loam and sandy peat. Ripened cut- 
tings, not deprived of any of their leaves, will root in 
sandy soil if plunged under a hand glass, in а moist 
heat. This genus is now merged into Clausena, and the 
proper name of the species below mentioned is Clausena 
Wampi. 
С. punctata (spotted). fl. white, small, disposed in racemose 
panicles. fr. edible, about the size of a pigeon's egg, yellow on 
the outside ; pulp white, rather acrid, but sweet. June апа July. 
L, leaflets ovate-lanceolate, acuminated, hardly unequal at the 
base. л. 206. Probably a native of China, 1795. A middle-sized 
troa, now cultivated (and partly naturalised) in many tropical 
countries. : 
COOPERIA (named after Mr. Joseph Cooper, à 
very successful cultivator, and at one time gardener at 
Wentworth House, in Yorkshire, the residence of Earl 
Fitzwilliam). ORD. Amaryllidec. Closely allied to 
Zephyranthes. There are two species of this genus 
in cultivation, with solitary Primrose-scented flowers, 
which are remarkable in the order, on account of their 
expanding during the night. They are hardy only in 
sheltered situations. For culture, propagation, &е., see 
Zephyranthes. 
C. Drummondi (Drummond’s). Л, white, the tube changing to 
red ; tube 4in. to біп. long; limb 1llin. to 2in. across, with ovate 
segments. August. l. linear, twisted, 10in. to 15in. long. А. біп.

America, 1774. SYN. C. Jacquini.

German astronomer, Copernicus). ORD. Palmew. А very 
small genus of about eight species of unarmed stove palms, 
with erect trunks, covered with the remnants of the leaf. 
stalks. Flowers hermaphrodite or polygamous, on axillary 
Spadices. Leaves fan-shaped, palmate, tufted. For cul- 
ture, see The best-known species, and the 
only one worthy of being described here, is C. cerifera.

COPROSMA (from kopros, dung, and osme, а smell; 
in allusion to the footid odour emitted by the plants). 
Овр. Rubiacem. A genus comprising about thirty-five 
species of greenhouse shrubs, the majority of which are 
natives of New Zealand and the Sandwich Islands, a 
few are from Australia and Oceania, and one from Juan 
Fernandez. None are worth cultivating for the sake of 
their flowers; but some deserve a place in a large con- 
Servatory for their small coral-red fruits. Cuttings 
should be made in March, taken off with a heel of the 
old wood, and placed in pots two-thirds filled with crocks, 
above which is a thin layer of rich, light material, and on 
the top a layer of sand. The pots should then be put 
in brisk bottom heat, in a propagating frame. During 
the time the cuttings are making root, only a very light 
sprinkling with water should be given, or they will damp 
off. When rooted, they should be potted into rich sandy 
soil, and gradually hardened off in a cold frame. Another 
method is to place the plants in a propagating bed, and 
layer the shoots which overhang the pot. Old plants 
should be potted in a similar compost to that recommended 
above, and should be pruned into shape every year if 
necessary.
