C. pubescens flore-pleno (downy, double-flowered).* fl. 2in. to 3in. across; petals long, narrow, wavy, and reflexed, flesh-colour, but ultimately bright rose; pedicels 2½in. to 3½in. long. Summer and autumn. l. alternate, hastate, downy. China, 1844. See Fig. 334.

Common Bindweed. fl. white, sometimes tinged with red; peduncles tetragonal, exceeding the petioles; bracts cordate, keeled, acute, longer than the calyx, but one-half shorter than the corolla. Summer. l. sagittate or cordate, very acute; hind lobes obtuse, or truncate, entire. Britain. A very troublesome weed. (Sy. En. B. 924.) There is a variety named incarnata, with rose-coloured flowers. North America. SYN. C. inflata. (B. M. 732.)
C. Soldanella (Soldanella-like).* Sea Bells. fl. pale red, with five longitudinal, yellowish plaits, large; peduncles angular, angles winged; bracts large, ovate, blunt, mucronate, generally shorter than the calyx. June. l. rather fleshy, reniform, entire or a little angular. Sea-shores, Britain. This pretty species can only be grown with success in a very sandy soil. (Sy. En. B. 925.)
CALYTHRIX (from kalyx, a calyx, and thrix, a hair; in reference to the lobes of the calyx, which each end in a long hair). ORD. Myrtaceæ. A genus of very pretty and interesting greenhouse Heath-like shrubs, natives of Australia. Flowers small; bracteoles two under each flower; they are either free or joined together at the base, sometimes in the form of an operculum. Leaves scattered, crowded, opposite, full of dots, axillary, solitary, almost sessile. They grow well in a mixture of loam, peat, and sand, with good drainage and firm potting. Cuttings, made from young shoots, will root in April or May, if placed in sand, under a bell glass, in a cool house.
