base, or adhering to the petals. Capsule 

 globose or ovoid, 3-valved. 



Culture and Propagation. — The 

 species described below are the ones 

 chiefly grown as annuals from seed, 

 except C. umbellata, which is treated as a 

 biennial. They like a light sandy soil in 

 warm places in the rock garden. As the 

 plants do not transplant weU, it is better 

 to sow seeds where the plants are to 

 flower, protecting them with handlights 

 or sheets of glass untU all danger of irost 

 is over. The flowers of most species ex- 

 pand only in bright sunshine, thus resem- 

 bling the Portulacas. 



C. discolor. — A ChUian plant 12-18 

 in. high, with fleshy obovate leaves, 

 narrowed at the base, pale green above, 

 purple beneath. Flowers in summer, 

 bright rose, 1^ in. across, with a yellow 

 tuft of stamens in the centre, borne on 

 long racemes. The blossoms are at first 

 drooping, but become erect when fuUy 

 expanded. This species is often called 

 C. elegans in gardens. 



Culture dc. as above. Seeds may be 

 sown in the open border in warm sheltered 

 situations, with plenty of sunshine, in 

 April and May, and even as late as the 

 end of, June, to secure a succession of 

 flowering till late in autumn. The seed- 

 lings when large enough may be thinned 

 out 6-8 in. apart. 



C. grandiflora. — A native of ChUi 1 ft. 

 high, with rather shrubby stems. Leaves 

 fleshy, rhomboid, acute, stalked. Plowers 

 in summer, 2 in. across, rosy, in loose 

 racemes ; calyx spotted with black. 



Culture ic. as above. 



C. Menziesi (C speciosa). — A Califor- 

 nian species with much-branched stems 

 at first prostrate, but afterwards turning 

 upwards 12-18 in. high. Leaves spathu- 

 late, much narrowed towards the base. 

 Flowers from June to September, deep 

 purple-crimson, ^-1 in. across. 



Culture do. — This is one of the most 

 beautiful members of the genus and looks 

 very effective grown in large patches. 

 Seeds may be sown at intervals from 

 April to July to keep up a succession of 

 blossom. 



C. nitida. — A pretty tufted species 

 about 6 in. high, native of Chili. Leaves 

 smooth, oblong, spathulate, sub-acute, 

 narrowed at the base. Flowers in sum- 



mer, rosy, about 2 in. across, and borne 

 in many-flowered leafy racemes. 



Culture Ac. as above for C. discolor. 



C. oppositifolia. — A pretty Californian 

 species with a thick and fleshy tuberous 

 rootstock, and oblanceolate leaves 2-2^ 

 in. long. The pure white or blush 

 flowers, each about 1^ in. across, are borne 

 in late summer, 3 or 4 on a stem 3-6 in. 

 high. The sepals are roundish and 

 sharply toothed, as are also the 5 deeply 

 cleft petals, surrounding a cluster of 

 about 20 stamens in the centre. 



Culture dc. as for C. umbellata below. 

 This species is rather tender and is 

 best wintered in a cold greenhouse in im- 

 favourable parts of the kingdom. C. 

 Tweedyi, a dwarf -tufted species with thick 

 fleshy leaves and bronzy flesh-coloured 

 flowers, would probably succeed if treated 

 in the same way, at least in the milder 

 parts of the kingdom. 



C. umbellata. — A distinct and pretty 

 Peruvian species about 6 inches high, 

 with radical, linear, acute, hairy leaves. 

 Flowers in summer and autumn, brilliant 

 magenta-crimson, less than 1 in. across, 

 in many-flowered cymose corymbs. 



Culture and Propagation. — This 

 species is a perennial on dry soils, and 

 may be grown in warm fully exposed 

 sunny parts of the rock garden. The seeds 

 should be sown in fine sandy soil in pots 

 or in the open some time during Sep- 

 tember, or in April and May as mentioned 

 above for C. discolor. If sown in pots the 

 seedlings should not be pricked out, as 

 they are apt to perish by such treatment, 

 but the whole potftd— soil and all— should 

 be carefoUy planted without breaking the 

 soil. In favourable parts of the kingdom 

 this species and also C. grandiflora will 

 often reproduce themselves from self-sown 

 seeds. 



CLAYTONIA. — A genus containing 

 about 20 species of fleshy annual or 

 perennial herbaceous plants, usually 

 smooth, sometimes with tuberous root- 

 stocks. Lower leaves stalked, upper ones 

 alternate or opposite. Stipules none. 

 Flowers in terminal racemes or cymes, 

 rarely axUlary or solitary. Sepals 2, 

 herbaceous, ovate, persistent. Petals 5, 

 hypogynous. Stamens 5, opposite the 

 petals, and adhering to them at the base. 

 Style 3-cleft or 3-furrowed. 



Culture and Propagation. — Clay- 

 tonias are adapted for the rockery or
