 C. gnaroldes (Guara-like). A synonym of C. rhomboidea. 



FIG. 465. FLOWERING BRANCH AND SINGLE FLOWER OF 

 CLARKIA PULCHELLA. 



C. pnlchella (pretty).* fl. purple, large ; petals deeply trilobed, 

 with a pair of small opposite teeth on the claws. Summer. I. 

 glabrescent, linear, h. lift, to 2ft. North America, 1826. See 

 Fig. 465. (B. R. 1100.) This species also has many single and 

 double-flowered varieties, more or less beautiful, which are fully 

 described in seedsmen's catalogues. 



C. rhomboidea (rhomboid) is a species with smaller purplish 

 flowers than either of the preceding. SYN. C. guaroides. 

 (S. B. F. G. 379.) 



CLARY (Salvia Sclarea). The leaves of this are 

 sometimes used in soups. The culture is very simple. 

 Seeds may be sown in early spring, in a warm sunny 

 border, and the plants ultimately thinned out to 18in. 

 apart. An annual sowing is necessary, as the plants die 

 after the seed ripens. 



CLAUSENA (commemorative of P. Clausen, a Danish 

 botanist of the seventeenth century). OBD. Rutaceae. A 

 genus of about fourteen species of stove evergreen trees, 

 occurring for the most part in India, a few being found in 

 Africa and tropical Australia. Flowers small, disposed in 

 loose panicles. Leaves impari-pinnate ; leaflets stalked, 

 pubescent. They thrive in rich loam ; young cuttings, 

 ripened at the bottom, and taken off at a joint, will root 

 in sand, under a hand glass, in heat. 

 C. corymblflora (corymb-flowered), fl. white. Loyalty Islands, 



C. pentaphylla (five-leaved), fl. white. June to August. I. with 

 five or seven pairs of leaflets, h. 20ft. India, 1800. 



CIiAVATE. Club-shaped ; the thick end uppermost. 



CLAVTJA (named after J. Clavijo Faxardo, a Spanish 

 naturalist, who translated Buffon's works into Spanish). 

 SYN. Theophrasta (of Linnaeus, not of Jussieu). OED. 

 Mtjrsinece. A genus of stove evergreen trees or shrubs. 

 Stems simple, unbranched, furnished at top with a 

 tuft of long, alternate, oblong-lanceolate, coriaceous, 

 spiny-toothed or quite entire leaves, somewhat in the 

 manner of palm-trees. Flowers in axillary or lateral 

 racemes, often secund. There are about twenty-five 

 species, all natives of tropical America, &c. They thrive 

 in a compost of peat and loam. Cuttings of half-ripened 

 shoots will root in sandy loam, with a surface consisting 

 wholly of sand, if placed in bottom heat, under a bell 

 glass.

C. fulgens (brilliant).* /. deep orange-red, very handsome; 

 racemes short, axillary. I. obcuneately spathulate, 1ft. or more 

 long. Stem simple, bearing a crown of leaves. Peru, 1867. 

 (B. M. 5626.) 



C. maorocarpa (large-fruited), fl. rather large ; racemes from 

 3in. to 12in. long, pendulous. I. spathulate-oblong, acute, stiff, 

 dotted beneath ; petioles hardly lin. long. h. 10ft. to 12ft. Peru, 

 1816. 



C. maorophylla (large-leaved). A synonym of C. Reideliana. 



C. ornata (adorned).* fl. orange-coloured ; racemes drooping, Sin. 

 to 4in. long. I. long-lanceolate, acute, spiny-toothed ; petioles 

 2iin. long. h. 10ft. to 12ft. Caraccas, 1828. SYN. Theophrasta 

 longifolia. (B. M. 4922.) 



C. Reideliana (Reidel's).* fl. orange-coloured ; racemes axillary, 



. I. sessile 



from amongst and beneath the crown of leaves. July. 



obovate-lanceolate, spinosely-serrate ; larger ones 12in. to 20in. 



long. Brazil. SYN. C.mncrophylla. (B. M. 5829.) 



Other two species are : Rodekiana and umbrosa. 



CLAW. The unguis or stalk of a petal ; the narrow 

 end.

CLATTONIA (named after John Clayton ; he collected 

 plants, mostly in Virginia, and sent them to Gronovius, 

 who published them in his "Flora Virginica"). OBD. Por- 

 tulacece. A genus of delicate little glabrous, rather succu- 

 lent, hardy annuals or perennials. Eacemes terminal. Leaves 

 quite entire ; radical ones petiolate, upper usually opposite 

 and sessile, and sometimes connate. Claytonias are of 

 easy culture, and suited for certain parts of the rockery 

 or wild garden. The tuberous-rooted species thrive best 

 in damp peat soil. They may be increased by seeds, which 

 sometimes ripen freely ; or by offsets, which may be sepa- 

 rated in spring or autumn. The fibrous-rooted species 

 being annuals, the seeds only require to be sown in the 

 open border in spring, in a rather moist situation. 



C. oarollnlana (Carolina). I. spathulate-oblong or oval-lanceo- 

 late. North America. (S. B. F. G. 208.) 



C. grandlflora (large-flowered). Synonymous with C. virginica. 



C. perfollata (perfoliate). fl. white, small ; lower .pedicels of 

 raceme in bundles. May to August. I., upper ones connate or 

 perfoliate, forming a roundish disk ; radical ones petiolate, oval- 

 rhomboid. Root fibrous. h. 3in. to6in. North-west America to 

 Mexico and Cuba, 1794. Annual. This species is naturalised in 

 many parts of Britain and other countries. (B. M. 1336.) 



FIG. 466. CLAYTONIA SIBIRICA, showing Habit and Single Flower. 



C. Slblxioa (Siberian).* fl. rose-coloured ; petals bifid ; raceme 

 secund. March. 1. oval ; radical ones petiolate ; cauline ones 

 two, opposite, sessile. Root fusiform, h. Sin. to 6in. Siberia, 

 1768. Perennial. See Fig. 466. (B. M. 2243.) 



C. virglnica (Virginian).* /.white; petals emarginate; pedicels 

 elongated ; raceme solitary, nodding. March. 1. linear-lanceo- 

 late, elongated ; radical ones very few. h. 3in. Roots tuberous. 

 North America, 1768. Perennial. SYN. C. grandiflora. (B. M. 

 941.)
