AN ENCYCLOPAEDIA OF HORTICULTURE. 



297 



Cerasus continued. 



serrated, with incurved, short, or callous teeth. Eastern United 

 States. A large deciduous tree, furnishing valuable timber. 

 (W. D. B. 48.) 



C. serrulate (saw-leaved).* Double Chinese Cherry, fl. pale 

 white or rose-tinted, double, disposed in fascicles. April. I. 

 obovate, acuminated, setaceously serrulated, quite glabrous ; 

 petioles glandular, h. 15ft. China, 1822. SYN. C. Sieboldii. 

 Deciduous. See Fig. 405. (R. H. 1866, 371.) 



C. Sieboldii (Siebold's). Synonymous with C. serrulata. 



C. sphaarocarpa (round-fruited), fl. white ; racemes axillary, 

 erect, small, shorter than the leaves. June and July. fr. nearly 

 globose, purple when ripe. I. glandless, shining, about 2in. long 

 and Ijin. broad, h. 10ft. to 12ft. Jamaica, 1820. Stove evergreen. 



C. virginiana (Virginian). Choke-Cherry, fl. white; racemes 

 erect, elongated. May and June. fr. globose, red. I. oblong, 

 acuminated, doubly-toothed, smooth ; petioles usually bearing 

 about four glands. Wood beautifully veined with black and 

 white, h. 20ft. to 80ft. Eastern United States, 1724. Deciduous. 



CERATIOLA (from Iteration, a diminutive of Iceras, a 

 horn ; in reference to the stigma radiating into four divi- 

 sions like little horns, as in the Carnation). ORD. Empe- 

 tracece. An upright, much-branched, evergreen, half-hardy 

 shrub, much resembling an Erica. When well grown, it is 

 a very handsome little plant. It thrives well in sandy 

 peat, to which may be added a little very fibry loam. It 

 will probably prove quite hardy in the West of England ; 

 but if grown out of doors in other parts of the country, 

 it should have protection during winter. Propagated by 

 cuttings, which should be placed in sandy soil, under a bell 

 glass. 



C. ericoides (Heath-like).* /. brownish, sessile, in the axils of 

 the upper leaves, rarely solitary, sometimes verticillate. June. 

 I. simple, alternate, exstipulate, spreading, needle-shaped, obtuse, 

 glabrous and shining, about Jin. long, sometimes crowded as if 

 verticillate. Berries globose, yellow. Florida, Carolina, 1826. 

 (B. M. 2758.) 



CERATODACTYLIS. See Llavea. 

 CERATOLOBUS (from Iceras, a horn, and lobos, a 

 pod; referring to the horned pod-like spathe). ORD. 

 Palmce. Slender-growing stove Palms, of great beauty, 

 and requiring culture similar to Calamus (which see). 

 C. ooncolor (one-coloured). I., sheath sub-strigose ; segments 



green beneath, fr. sub-globose. Sumatra. 

 C. glaucescens (milky-green-leaved).* 1. pinnate, 1ft. to 2ft. long ; 



pinnae somewhat cuneate, lengthened out into a tail-like point ; 



edges erose, dark green on the upper surface, grey below ; petioles 



sheathing, densely armed with slender spines. Java. This makes 



an elegant table plant. 



CERATONIA (from Iteration, a horn or pod ; in allu- 

 sion to the shape of the pods). Algaroba Bean, or Carob. 

 This plant is called by Theophrastus, Keronia; by Dios- 

 corides, Kerateia. OKD. Leguminosce. An evergreen tree, 

 with a thick trunk, and abruptly-pinnate, coriaceous, 

 shining leaves. It thrives well in the South of England, 

 in any ordinary garden soil, if afforded the protection of 

 a wall, and slightly sheltered during winter. Eipened 

 cuttings will root if planted in sand, with a hand glass 

 placed over them. 



C. Siliqna (podded). Bean-tree, Carob-tree, or Locust-tree, fl. 

 red, small, racemose. September. I., leaflets oval, obtuse, flat, 

 coriaceous, shining, dark green. Plant unarmed, h. 30ft. to 

 50ft. South Europe, 1570. This tiee is much cultivated in the 

 South of Europe for the sake of the pods, the pulp of which 

 is eaten ; these are 4in. or more in length, and are, as well as 

 the seeds, of a dusky ferruginous colour. (A. B. K. 567.) 



CERATOFETALTJM (from keras, a horn, and petalon, 

 a petal ; the petals are jagged so as to resemble a stag's 

 horn). ORD. Saxifragece. A genus containing a couple of 

 species of greenhouse trees, limited to New South Wales. 

 Flowers small, in terminal trichotomous cymes or corymbose 

 panicles. They have opposite leaves, with one to three 

 digitate leaflets, articulate on the petiole; stipules very 

 small, caducous. For culture, see Callicoma. 

 C. apetalum (without petals), fl. greenish-yellow. I., leaflets 



usually solitary (occasionally three on luxuriant shoots or young 



trees), h. 50ft. to 60ft. 

 C. gummlferum (gum-bearing), fl. yellow, in terminal panicles. 



June. I. ternate ; leaflets three, lanceolate, serrated, coriaceous, 



and smooth, h. 30ft. to 40ft. 1823. 



CERATOFTERIS (from keras, a horn, and pteris, a 

 fern). ORD. FiUees. A very curious stove aquatic annual 

 monotypic genus. Sori placed on two or three veins, which 

 run down the frond longitudinally, and are nearly parallel 

 with both the edge and midrib. Capsules scattered on the 

 receptacles, sessile, globose, with a ring which is either 

 complete, or more or less partial or obsolete. Involucre 

 formed of the reflexed margin of the frond, those of the 

 two sides meeting against the midrib. When nicely grown 

 in water, this is a very handsome plant, and not inaptly 

 called the Floating Stag's-horn Fern. The spores must be 

 preserved and sown early in spring, in a pot of very moist 

 loam; they germinate rapidly if plunged in water, in 

 February. Young plants may also be obtained from the 

 proliferous buds, by pegging the sterile fronds on to a 

 surface of moist earth. It succeeds best when the pot 

 containing it is plunged to the rim in water. 

 C. thalictroides (Thalictrum-like).* sti. tufted, thick, inflated. 

 fronds succulent, the barren ones floating, simple or slightly 

 divided when young, bi- or tripinnate, with narrow linear seg- 

 ments, when mature ; fertile ones bi- or tripinnate ; ultimate 

 segments pod-like. Tropics, in quiet waters. SYN. Parkeria 

 pteroides. 



CERATOSTEMA (from keras, a horn, and stemon, a 

 stamen ; in reference to the anthers being bluntly spurred 

 at the base). ORD. VacciniaceoB. Very pretty greenhouse 

 evergreen shrubs. Flowers almost sessile, lateral and ter- 

 minal, pedunculate ; corollas large, scarlet. Leaves oblong, 

 on short petioles, almost veinless, coriaceous, rounded, and 

 sub-cordate at the base. They require a compost of sandy 

 loam and peat ; and are readily increased by cuttings, 

 planted in sand, and placed under a glass. 

 C. longlflorum (long-flowered). fl. crimson. Andes of Peru, 



elevation 12,000ft. above sea-level, 1846. (B. M. 4779.) 

 C. speciosum (showy).* /. bright orange-red, about Ijin. long; 

 spikes short, axillary, secund, drooping. I. coriaceous, ovate- 

 lanceolate, with a short twisted petiole. Ecuador, 1870. 

 CERATOZAMIA (from keras, a horn, and Zamia, 

 another genus of Cycadacece, which this much resembles ; 

 in reference to the horned scales of the cones). ORD. Cyca- 

 dacece. Stove plants, distinguished from Zamia in having 

 the thickened apices of the scales of the male and female 

 cones bicornute (i.e., two-horned), instead of hornless. Leaf- 

 lets articulated. Trunks short. They require a moist 

 atmosphere, and a compost of rich light loam and rotten 

 leaves. Propagated by seeds, and sometimes by suckers 

 and divisions ; but imported plants give most satisfaction. 

 C. fusco-virldis (dusky-green).* I. 3ft. to 4ft. long, broadly pin- 

 nate, of a fine arching habit ; pinnae deep green, 6in. to 7in. long, 

 sessile, lanceolate, and tapering to a longish point. Trunk fur- 

 nished with broadish scales, surrounding each of the leafstalks, 

 which are nearly terete above and asperous along the edges. 

 Young leaves of a rich bronzy-chocolate colour, but gradually 

 changing to olive-green and, finally, deep green. Mexico, 1879. 

 C. Knsterlana (Kuster-s). I. 2ft. to 4ft. long, pinnate, spread- 

 ing ; pinnae semi-lunate, tapering to a sharp point, coriaceous, 

 6in. to lOin. long, about Jin. broad, dark green. Mexico. 

 C. mexicana (Mexican).* Male : I. pinnate, about 6ft. long ; 

 pinnae coriaceous, sessile, cordate-lanceolate, tapering to a sharp 

 point, 9in. to 12in. long, Ijin. broad, dark green ; petioles spiny 

 for about half their length, very stout at the base. Mexico. 

 Female : I. pinnate, 3ft. to 4ft. long, pendulous ; pinnae 6in. to 

 lOin. long, tapering to a point, rich dark green on both surfaces ; 

 naked portion of petiole armed with short white spines. Stem 

 stout. Mexico. 



C. Miqueliana (Miquel's).* I. pinnate, spreading ; pinnae coria- 

 ceous, oblong, abruptly tapering to a point, 6m. to 12in. long, 

 2in. broad, dark green. Stem slender. Mexico. 

 CERBERA (so named from Cerberus, of mythlogical 

 note, on account of its poisonous qualities). ORD. Apocy- 

 nacece. Stove evergreen shrubs or trees. Peduncles extra- 

 axillary at the tops of the branches ; corolla funnel-shaped . 

 tube pilose inside at top. Leaves scattered, quite entire. 

 They require a rich fibry loam, and cuttings of young, 

 rather ripe shoots will root in sand, if planted in April, in 

 bottom heat. 



C. Manghas (Manghas). fl. white, with a pink centre ; petals 

 ovate, with an incurved, sub-retuse apex ; panicle terminal, corym- 

 bose, large, open. July to September. I. oblong-lanceolate, acute, 



tapering downwards, approximate, shiny. 

 (U M. 1845.)
