 keeled, lanceolate, scabrid on the back. I. linear, flat, striated, 

 glabrous on the outer, scabrid on the inner surface, A. 1ft 



C. radiate (radiate). JL, spikes many-fascicled, nearly erect ; 

 florets subulate, smooth. Summer. L narrow. A. 6in. West 

 Indies, 1739. 



CHIiOROGAIiUM (from chloros, green, and gala, 

 milk; referring to their green juice). Soap-plant. OBD. 

 Liliace&. A genus of curious and distinct hardy bulbs, 

 containing three species, all from California. For culture, 

 see Ornithogulum. The only one in cultivation is 

 C. pomeridianum. 



C. Leichtlini. - Camassia esculcnta Leichtlini. 

 C. pomeridianum (afternoon).* /* white, purplish-veined ; stems 

 panicled, branched. June. 1. flaccid, glaucous, with the edges 

 and nerves rough, k. 2ft. California, 1819. STXS. Anthericum 

 pomeridianum (B. B. 564), Ornithogalum dimrieatum (B. B. 1842, 

 28), and Phalawium pomeridianum. The bulbs are frequently 

 used in California as a substitute for soap. The flowers only 

 open after mid-day, hence the specific name. 

 CHLOROFHYIiIi. The green, resinous, granular 

 colouring matter of plants. 



CHIaOROPHYTTJM (from chloros, green, and phyton, 

 a plant). OED. Liliacece. Greenhouse or store evergreen 

 perennials, allied to Anthericum. They are of easy culture 

 in a rich sandy loam. Propagated by seeds or suckers, or 

 by divisions of the plant in spring. All the species are 

 white-flowered, and are of no special horticultural value. 

 Out of the forty species known to science, the following 

 have been, or are, in cultivation : a fine, Boirlcerii. elatum, 

 and falcatwn. 



CHIiOROSFATHA (from chloros. green, and spathe, a 

 spa the : green spathe). OED. Aroidece (Araceae). Allied, 

 and requiring similar culture, to Xanthosoma (which see). 



C. Kolbii (Kulb's). 'lhi.>, the only species, is a spotted-stalked, 

 pedate-leaved, stove tuberous perennial, with elongated, cylin- 

 drical, convolute spathes. Chiefly of botanical interest New 

 Grenada, 1878. (B. G. 935.)

 wood ; in allusion to the colour of the wood). OBD. Me- 

 liacecB. A fine stove timber tree, having terminal panicles 

 of small, whitish flowers, and abruptly pinnate leaves. It 

 succeeds well in a compost of loam and peat. Ripe cut- 

 tings, with their leaves intact, will root in sand, under a 

 hand glass, in a moist heat. 



C. Swietenia (Van Swieten's). Satin-wood Tree. I., leaflets 

 many pairs, unequal, orate, somewhat rhomboid, obtuse. A. 50ft 

 India, 1820. The wood of this tree is of a deep yellow colour, 

 remarkably close-grained, heavy, and durable. STN. Svietenia, 

 Chloroxylon. (B. P. S. 11.)

 botanist, author of several monographs in De Candolle's 

 " Prodromus ") OBD. Rutaceoe. A very beautiful shrub, 

 quite hardy in the southern and many other parts of 

 Britain, with the protection of a wall It thrives in a 

 southern or western aspect, and requires a compost of loam 

 and peat, to which a small quantity of sand and leaf mould 

 is added. It may be easily propagated by ripened cuttings, 

 which will root freely in sand, under a hand glass, in 

 gentle bottom heat, during spring and early summer. 

 C. ternata (ternate). JL white, sweet-scented ; peduncles axillary 

 at the tops of the branches, simple, or branched, with bracts at 

 the divisions under the pedicels, which are channelled beneath. 

 July. L opposite, ternate, stalked, bright green, full of pellucid 

 dots. h. 6ft Mexico, 1825. (B. H. 1869, 332.) 

 CHOKE-CHERRY. See Cerasus virginiana.

 Louis XV. ; author of "Abrege de L'Histoire des Plantes 

 usuelles," 12mo, Paris, 1712). OBD. Rubiacece. Stove ever- 

 green shrubs. For culture, see Izora, from which the 

 present genus differs in habit and inflorescence, but more 

 particularly in the fruit containing a hard nut. 

 C. fasciculate (fascicled), jt. white; pedicels two or three 

 together, axillary, one-flowered. I ovate, acute, glabrous, on 

 short petioles. A. 5ft Grenada, 1825.

 in the pod). OBD. Cruciferae. A genus of about seven 

 species of annual or biennial, branched, slender, smooth

lanceolate, toothed ; lower ones pinnatifid. A. 4in. to 6in.

CHORIZEMA (from chores, a dance, and zema, a 

 drink ; this genus was, says Don, originally discovered by 

 LabOlardiere, upon the south-west coast of New Holland, 

 at the foot of the mountains, near a spot where, after being 

 tantalised with finding many salt springs, his party had just 

 met with an ample supply of fresh water; this welcome 

 refreshment, of which he speaks feelingly in his book, 

 seems to have suggested the name). OBD. Leguminotce. 

 Greenhouse evergreen sub-shrubs, with alternate, simple, 

 sinuately toothed, or entire leaves. They are mostly trained 

 on globe and other trellises, with excellent effect, the whole 

 trellis being lighted up with the brilliant beauty of their 

 flowers, slightly toned down by the pleasing forms and 

 refreshing variation of the leaves. They are admirably 

 adapted for clothing dwarf columns or pillars, and covering 

 dwarf walls. They also form fine loose bushes, if allowed 

 to grow freely, and produce a number of shoots, the outer 

 ones hanging over and partly hiding the pots They all 

 grow freely in a mixture of peat and loam, fibry, but not too 

 rough, with a large proportion of sharp silver sand. The 

 drainage should also be liberal, and the pots scrupulously 

 clean. In potting, the soil should be pressed firm, as for 

 Heaths, Azaleas, and other hard-wooded plants. Loose 

 potting kills thousands of choice plants every year. A 

 certain degree of solidity is needful in the potting of hard- 

 wooded plants, to enable the roots to grip the fresh soil 

 If they miss doing so, the new soil sours, the roots remain 

 where they are, or the extremities their most vital parts 

 rot off, and the plants languish and die. If the soil is used 

 in a proper condition as regards dryness, it is hardly pos- 

 sible to overdo the compression with the fingers and hands. 

 The best time to pot these plants is just as the shoots begin 

 to break afresh. They may finish their growth in a common 

 greenhouse, or have a little more heat during their growing 

 period. At the end of summer and during the early 

 autumnal months, they may be placed out of doora, in a 

 sheltered place, care being taken to stand the pots on a 

 worm-proof bottom. Early in the autumn, the plants 

 should be taken under glass, before being soaked or sod- 

 dened with heavy rains.
