THE DICTIONARY OF GARDENING, 



COBURGIA. This is now included in the genus 

 Stenomesson. 



COCCOCYFSELUM (from kokkos, fruit, and kypaele, 

 a vase ; in allusion to the form of the fruit). STNS. Sice- 

 Hum, Tontanea. ORD. Rubiaeeai. A genus of creeping 

 soft-wooded stove plants. Peduncles axillary, solitary, 

 and in the alternate axils, each bearing a few-flowered 

 head, surrounded by a short involucre. Leaves opposite, 

 on short petioles ; stipules subulate, solitary on both sides. 

 The species are of easy culture in a mixture of peat and 

 sand. Increased readily by separating the creeping stems. 

 C. campanuliflorum (bell-flowered), fl. bright pale blue, in 



axillary or terminal heads ; throat yellow. 7. roundish oval, 



hairy, stalked. Brazil, 1827. SYN. Hedyotis campanuliflora. 



(B. M. 2840.) 

 C. cordifolium (heart-shaped-leaved), fl. white, pubescent, dis- 



posed in almost globose heads ; peduncles ultimately equalling 



the petioles in length. I. cordate, obtuse, hairy. Brazil. 

 C. metallicum (metallic-leaved). JL white. J. with a metallic 



lustre. Guiana, 1866. 

 C. repens (creeping).* fl. blue, almost sessile, collected in the 



axils of the leaves ; heads few-flowered ; peduncles very short 



while bearing the flowers, afterwards becoming more elongated. 



May. I. ovate, pubescent on both surfaces. West Indian Islands, 



1793. Annual. 



COCCOLOB A (from kokkos, a berry, and lobos, a pod ; 

 in reference to the fruit). Seaside Grape. OBD. Poly- 

 gonece. A. rather large genus of stove evergreen trees, 

 some of which are ornamental. They grow well in good 

 loam. Cuttings (of most of the species) of ripened wood, 

 with leaves entire, taken off at a joint, will root freely in 

 sand, under a bell glass. The best species are given below. 

 C. obovata (reversed-egg-shaped). fl, white, green. A 50ft. New 



Grenada, 1824. 



C. pubescens (downy), fl. white, green. West Indies, &c., 1690. 

 C. nvifera (grape-bearing), fl. white, fragrant. I. orbicular, cor- 



date, leathery, bright glossy green. A. 20ft West Indies, &c., 



1690. (B.M.3130.f 



COCCUIiUS (from coccus, the systematic name of 

 cochineal, applied to this genus on account of the greater 

 part of the species bearing scarlet berries). SYN. Wend- 

 landia. OBD. Menispermacece. A genus of stove, green- 

 house, or hardy evergreen climbing or twining shrubs. 

 Cymes or panicles axillary ; those bearing the male flowers 

 usually many-flowered ; those bearing the female ones few- 

 flowered. Leaves ovate or oblong, entire, rarely lobed. 

 They thrive well in a mixture of loam and peat. Cuttings 

 of half-ripened side shoots will root easily in spring or 

 summer, if planted in sand and placed in bottom heat, 

 under a bell glass. 

 C. carolinus (Carolina), fl. greenish, in axillary racemes or 



panicles. July. I. downy beneath, ovate or cordate, entire or 



sinuate-lobed. h. 20ft. United States. Pl 



Hardy. 

 C. laurifolins (Laurel-leaved). fl. white, green, small ; peduncles 



lateral and axillary, branched at the top, rather shorter than 



the petioles. January. I. oblong, acuminated, smooth, shiny. 



Sub-tropical Himalayas, 1820. An ornamental shrub, with bright 



green leaves, remarkable for being a compact bush, whilst nearly 



all the other species are twiners. Half-hardy. 

 C. ThunbergiKThunberg's). fl. axillary, panicled. I. ovate, 



obtuse, with a point, under surface villous ; lower leaves some- 



what triangular, upper ones orbicular. Japan. Hardy.

COCHIiEARIA (from cocldear, a spoon; the leaves 

 of most species are hollowed, like the bowl of a spoon). 

 Scurvy Grass; Spoonwort. OBD. Cruciferae. Annual or 

 perennial herbs, usually smooth and fleshy. Racemes 

 terminal ; pedicels bractless, spreading, filiform or some- 

 what angular. Leaves very variable ; radical ones usually 

 stalked ; cauline ones often auriculate-sagittate. There 

 are about twenty-five species, widely distributed over the 

 temperate and cold regions of the Northern hemisphere. 

 Cochlearias are of the simplest culture in ordinary garden 

 soil, but scarcely any are worth growing for ornament. 



Plant minutely pubescent. 



Cochlearia continued. 



Propagated by seeds (which are produced freely by most 

 of the species), sown in the open air, in early spring. 



FIG. 479. COCHLEARIA ARMORACIA. 



C. Armoracia (Horse-Radish), fl. white, with a spreading calyx. 

 May. I., radical ones large, oblong, crenated ; cauline ones 

 elongated, lanceolate, toothed or cut. Root large, fleshy. 

 h. 2ft. Eastern temperate Europe (naturalised in Britain). See 

 Fig. 479. For detailed culture, see Horse-Radish.
