AN ENCYCLOPEDIA OF HORTICULTURE.

CHJETOGASTRA (from chaite, a bristle, and gasier, 

 a belly; in allusion to the tube of the calyx being beset 

 with bristles or scales). OED. Melastomaceae. The plants 

 formerly placed here are now generally distributed in the 

 genera Brachyotum and Pleroma. Greenhouse or stove 

 shrubs or herbs, for the most part clothed with strigose 

 hairs. Flowers terminal. Leaves three to five-nerved, 

 quite entire, or hardly serrulated. They are of easy cul- 

 ture in peat and loam. Propagated by seeds, sown in 

 March ; or by cuttings (of the perennials), in sandy peat. 

 C. gracilis (slender).* Jl. red, lilac, axillary ; pedicels one-flowered; 

 terminal ones three-flowered. I. almost sessile, lanceolate-linear, 

 acute, quite entire, villous. Plant erect, nearly simple, naked 

 at the apex. h. 1ft. Brazil, 1848. Greenhouse perennial. 

 C. lanccolata (lance-shape-leaved) jl. white ; peduncles trr 

 chotomous, axillary and terminal. January. I. petiolate, broadly 

 lanceolate, acuminated, serrulately ciliated, villous on both sur- 

 faces, h. 1ft. Peru, 1820. Stove annual. 



C. strigosa (short-bristled).* Jl. rosy-purple ; cymes terminal, 

 pedunculate, few-flowered. August. I. on short petioles, ovate, 

 acute, hardly three-nerved, quite entire, with a few thick, 

 scattered, adpressed bristles on the upper surface, h. 1ft. West 

 Indies, 1848. Greenhouse evergreen shrub. 

 CHALAZA. That part of a seed where the nucleus 

 joins the integuments. 



CTT A TVT TEf* ATTA, (from chamai, on the ground, dwarf, 

 and batos, a bramble; referring to its low growth and 

 bramble-like flowers). OED. Rosaceae. A very pretty half- 

 hardy evergreen shrub, thriving in a cool frame or green- 

 house, in light loam, to which may be added a little peat. 

 Cuttings should be struck in sand, in a cool frame. 

 C. follolosa (leafleted).* Jl. white, about fin. in diameter; cymes 

 four to five-flowered, terminal. 1. broadly-ovate, about 2in. long, 

 tripinnately dissected. Young shoots clothed with a glandular 

 pubescence, h. 2ft. to 3ft. Sierra Nevada, 1859. See Fig. 414.

CHAM2ECISTUS. See Rhododendron Cliamae- 

 cistns. 



CHAM2ECYPARIS (from chamai, on the ground, 



i.e. dwarf, and Kuparissos, Cypress; the Bastard or 



Dwarf Cypress). White Cedars. STN. Retinospora. OED. 



Coniferae. Hardy evergreens. The present genus ranks 



extremely close to Cupressus, the principal distinction 



between the two being the more numerous ovules beneath 



the fertile scales of the latter. They are very pretty, 



and thrive best in a moist soil, in a rather protected 



situation. Propagated freely by seeds; but mainly by 



cuttings, put in during October. Select young side 



shoots, with a heel; insert in well-drained pots of sandy 



soil, and place in a close cold frame, keeping fairly moist 



through the winter. In February, they will be calloused, 



and should be placed in gentle heat; they will then root 



freely. This genus, like most others of the same order, 



is overloaded with synonyms, and mere varieties are often 



elaborated into species most of them known in gardens 



under the name of Retinospora, others as Cupressus. 



C. Boursieril (Boursier's). A synonym of C. Lawsoniana,. 



C. decussata (decussate). A synonym of C. ericoides. 



C. ericoides (Heath-like). I. linear, spreading, densely arranged 



in four ranks on the slender branchlets, somewhat rigid and 



acute ; bright green above, glaucous beneath, assuming a ruddy 



tint in winter. Branches very numerous, furnished with short 



branchlets. h. 3ft. to 4ft. A well-known dwarf, compact, conical 



bush, of garden origin. SYNS. C. decussata, Retinospora decussata 



and juniperoides. 



C. filicoides aurea (golden fern-like). A synonym of C. tetra- 



gona aurea. 



C. filifera (thread-bearing).* I. subulate, pointed, distant, in 

 alternate pairs, fulvous-green colour. Branches spreading; 

 secondary ones alternate, long, distant, furnished, on one side 

 principally, with numerous thread-like pensile branchlets of 

 various lengths ; terminal ones longer, filiform. Japan, 1867. 

 A dwarf tree, with irregular outline. SYN. C. pisij 'era filifera. 

 C. Keteleeri (Keteleer's). A synonym of C. obtusa. 

 C. Lawsoniana (La wson's).* Jl., mala catkins bright crimson, 

 terminal, numerous, produced when the trees are in a young 

 state. I. dark glossy green, more or less tinged with a glaucous 

 hue, very minute and closely imbricated, obtuse or acute, 

 usually furnished with an obscure tubercle towards the apex, 

 cones about the size of large peas, and produced in great pro- 

 fusion. Branches short, and spreading ; branchlets crowded. 



Chamsecyparia continued. 



pendulous fern-like, and feathery. Trunk comparatively slender. 

 A. 75ft. to 100ft North California, 1853. A very splendid hardy 

 evergreen tree, usually known in gardens under the name of 

 Cupressus. It is easily propagated by seeds, but the numerous 

 beautiful varieties are best increased by grafting upon seedling

stocks of the species. SYNS. C. Boursierii and Cupressus Law- 

 soniana. See Fig. 415. The varieties of this species are extremely 

 numerous; the following are described as being the best, in 

 Veitch's "Manual of Coniferae": 



C. L. albo-spica (white - spiked.)* Terminal growth and tips of 

 the branchlets creamy- white. Growth rapid, but less dense than 

 the type. 



C. L. albo-variegata (white-variegated).* Branchlets and 

 foliage very deep green, profusely spotted and blotched with 

 white. Of dwarf, compact, and conical habit. 



C. L. argentea (silvery).* Branches longer and more slender than 

 those of the type ; foliage of almost silvery whiteness. 



C. L. argenteo-variegata (silvery-variegated).* Many branch- 

 lets and leaves creamy-white, interspersed among the deep green 

 foliage. 



C. L. aureo-variegata (golden- variegated).* This differs from 

 the type in having many of its branchlets bright yellow. 



C. L. ereota-viridis (erect-green).* Habit fastigiate and tapering, 

 with foliage of a lighter and brighter green than the type. It is 

 very ornamental and distinct. 



C. L. filiformis (thread-like). 

 Habit sub-pendulous. 



C. L. gracilis pendula (gracefully pendulous).* Branches long, 

 gracefully pendulous. A handsome kwn plant, of vigorous growth. 



Branches excessively elongated.
