Callirhoe — continnetL 

 Malvareie. A genus of elegant annual or perennial herbs, 

 natives of North America. They are of extremely easy 

 cultivation, thriving in a compost of light, I'ioh, sandy loam. 

 Propagation of the perennial species may be effected by 

 means of both seeds and cuttings ; of the annuals, by 

 seeds only. Seeds should be sown in spring, either out- 

 side, or in pans in a cold frame. Young cuttings should be 

 taken and dibbled in sandy soil in a frame. 



C digltata (fingered).* ji. reddish -pui-ple ; pedimcles long, axillary, 

 one-flowered. Summer. I. sub-peltate, six to seven-parted, with 

 linear-entire or two-parted segments ; upper ones more simple. 

 k. 2ft. to 3ft. 1824. Perennial. (S. B. F. G. 129, under the name 

 of yuttallia digitata.) 



C. ijQVOlucrata (involucrate).* jt. crimson, nearly 2in. across, 

 loosely panioled. Summer. L divided nearly to the base, three 

 to five-parted ; segments narrow, lanceolate, three to five-toothed, 

 hairy on both surfaces. Habit procumbent; stems hairy, h. bin. 

 Perennial. (G. W. P. A. 26.) Sy^. Malva involucrata{B.U.^bSl). 



C. Papaver (Poppy-like).* Jl. violet-red ; sepals ovate-acute, 

 ciliated. Summer, i., root leaves lobed or pedate ; lower stem 

 leaves palmato-pedate, upper digitate or simple, h. 3ft. Louisiana, 

 1833. Perennial. Syn. yuttallia Papaver. (B. M. 3287.) 



C. pedata (pedate-leaved). ji. cherry-red, panicled. August. 

 I. hiciniately-pedate ; upper ones tritid. h. 2ft. to 3ft. 1824. 

 Annual. (R. H. 1857, 148.) 



C. triangnlata (triangular-leaved), fi. pale purple. August. 1836. 

 Perennial. Syn. Nuttallia corrfa^a (under which name it is figured

CAIiLISTEMOX (from lallos, beauty, and stemon, 

 a staTTiPn ; in mo.st of the species, the stamens are of a 

 beautiful scarlet colour) . Ord. 

 Myrtacece. Handsome greenhouse 

 evergreen shrubs or trees, having 

 the inflorescence rising from the 

 old branches in crowded spikes, as 

 in the species of Melaleuca^ but 

 with the stamens free, as in Me- 

 trosideros. Leaves elongated, stiff, 

 alternate, usually lanceolate. All 

 the species of this genus are very 

 ornamental and neat in habit. 

 They are well adapted for a con- 

 servatory. The soil best suited 

 for them is a mixture of loam, 

 peat, and sand. Ripened cuttings 

 strike root in sand, nnder a band 

 glass ; seeds are freqiiently pro- 

 duced on large plants, and these 

 may also be used to increase the 

 stock, but they do not produce 

 flowering plants for a considerable 

 time ; whereas plants raised from 

 cuttings, taken from flowering 

 plants, come into flower when 

 small. 



C. linearis (linear-leaved).* yf. scarlet ; 

 calyce-s clothed with velvety pu- 

 bescence. June. I. linear, stiff, acute, 

 keeled beneath, channelled above, vil- 

 lous when young, h. 4ft. to 6ft. New 

 South Wales, 1T88. 

 C. lophanthus (crest-flowered). Sy- 



nunyuiuus with C. aalinnm. 

 C. salignus (\villow). jl. straw-co- 

 loured, distinct, spicate, nearly ter- 

 minal ; petals rather pubescent, cili- 

 ated ; calyx pilose. June to August. 

 I. lanceolate, attenuated at both 

 ends, mucronate, one-nerved, villous 

 when young, as well as the branches. 

 h. 4ft. to 6ft. Australia. 1806. Svn. C. 

 lupiiauthiLi. (L. B. C. 1302.) 

 C. speciosns (showy).* /. scarlet; 

 calyx villous. March to July. I. lan- 

 ceolate, mucronate, flat, middle nerve rather prominent; when 

 young, rather .silky from adpre.ssed villi, and reddish, h. 5ft. to 

 10ft. West Australia, 182^. SYN. Metrosidero* sveciosa. See 

 Fig. 327. (B. M. 1761.)

CALIiISTEFHUS (from l-allistof!, most beautiful, and 

 stephua, a crown ; in allusion to the appendages on the 

 ripe fruit). China Aster. Stn. CalUsfemma. Ord. Com- 

 positce. A hardy annual, requiring an open situation and 

 a rich loamy soil. Involucre of many fringed bracts ; 

 receptacle naked, pitted ; pappus double. Propagated 

 by seed, sown in a hotbed in March, the seedlings being 

 hardened off and transplanted in May. For culture of 

 these much grown plants and their varieties, see Aster.

C. chinensis (Chinese).* Jl-heads dark purple. July. t. ovate, 



coarsely toothed, stalked ; stem ones sessile, cuneate at the 



base. Stem hispid. Branches with single heads, h. 2ft. China, 



1731. See Fig. 528. 



CAIiIiITRIS (probably altered from Jiallistos^ most 

 beautiful; referring to the whole plant). Ord. Conifer cb. 

 Syn. Frenela. Half-hardy evergreen shrubs or small trees, 

 with long, very slender-jointed branches, and often very 

 minute, scale-like, persistent leaves. Flowers moncecious.
