COCCOLOBA 



807 



branched. Mex. B.M. 851. F.S. 14:1467. There is a 

 white-fld. form (C. alba, Hort.), and one with variegated 

 Ivs., var. variegdta, Hort. The terminal 1ft. is repre- 

 sented by a tendril (Fig. 1007). Sometimes there are 

 indications of tendrils on other Ifts. (Fig. 1008), mak- 

 ing the plant an interesting one for students of mor- 

 phology. 



stipularis, Benth. (Rosenbergia stipulans, House). 

 Resembles the preceding species but the sepals ovate, 

 tapering to a broadly acuminate apex (the sepals of 

 C. scandens being broadly ovate or suborbicular). Mex. 





1007. Normal leaf of Cobaea scandens. 



macrostSma, Pav. (Sometimes erroneously written 

 macrostema and macrostemma.) Sis. climbing 6-10 ft.: 

 Ivs. alternate, of 3 pairs of obovate Ifts. : fls. solitary, on 

 a 2-lvd. long peduncle, the petals yellow-green; sta- 

 mens at least 1^ in. longer than the corolla. Guate- 

 mala. B.M. 3780. 



C. minor. Marten &. Galleotti. A small vine of which little 

 is known, but cult, in Amer. in botanic gardens and fanciers' 

 collections. It has small fls., borne on stalks shorter than the Ivs. 

 Mex. C. Pringlei, House (Rosenbergia Pringlei, House). A gla- 

 brous, high-twining vine: Ifts. 6, the basal pair oblong-lanceolate, 

 hastately clasping: peduncles 4-5 in. long; calyx-lobes green, her- 

 baceous, scarcely 1 in. long and half as broad; corolla pure white, 

 2 in. long; stamens exserted less than Y-iva.. Mex.

COBNUT: Corylus. ' N. TAYLOR, f 



COBURGIA: Stenomesson. 



COCA. The leaves of Erythroxylon Coco, used in 

 medicine. Sold chiefly as a fluid extract. Cocaine is the 

 famous local anesthetic. See Erythroxylon. 



COCCINIA (Latin, scarlet; referring to the orna- 

 mental gourds). Cucurbitdcese. Tender perennial vines, 

 usually with tuberous roots, grown for ornament mostly 

 indoors. 



Leaves angled or lobed, sometimes glandular: fls. 

 white or yellowish, large, staminate and pistillate on 

 different plants or sometimes on different branches of 

 the same plant; calyx short, often campanulate: fr. a 

 small, scarlet gourd, sometimes marbled, with an insipid 

 pulp. Twenty species from the tropics of Asia and Afr. 

 A. Cogniaux in DC., Mon. Phan. 3:528. C. cordifolia 

 is treated as a tender annual, requiring an early start 

 and no special cult. The genus is sometimes referred 

 to Cephalandra. 



A. Tendrils simple: male fls. solitary: Ivs. small. 

 cordifdlia, Cogn. (C. indica, Wight & Arn.). Height 

 about 10 ft., perfectly smooth: Ivs. small, 1-2 in. long, 

 glossy, ivy-like, short-petioled, obtusely 5-angled: fl. 

 white, bell-shaped, the staminate solitary: fr. roundish 

 at both ends, about 2 in. long, 1 in. thick. India. 



AA. Tendrils bifid: male fls. in racemes: Ivs. large. 

 palmata, Cogn. (Cephalandra palmdta, Lond.). At- 

 taining 30 ft.: Ivs. large, 3-4 in. long and wide, long- 



petioled, palmately 5-lobed: fls. yellowish: fr. ovate, 

 acute. Natal. Intro, by P. Henderson & Co., 1890. 

 A rare greenhouse plant. 



C. Dinteri, Andr6, with palmate Ivs. and handsome scarlet fra., 

 may be in cult. S. Afr. R.H. 1900:268.

COCCOLOBA (Greek, lobed berry, referring to the 

 ends of the pear-shaped fruit) . Sometimes spelled Coc- 

 colobis. Including Campderia. Polygonacese. Tropical 

 shrubs, trees or rarely tall woody climbers, grown for 

 their fruits and usually large glossy leathery leaves. 



Leaves alternate, always entire: fls. small, in axillary 

 or terminal spike-like racemes, usually some shade of 

 green or yellow-green; sepals 5, herbaceous; petals 0; 

 stamens 8, exceeding the perianth: fr. berry-like, with 

 a small stone, often edible. About 125 species in the 

 American tropics and reaching to Fla. C. platyclada is 

 now referred to Muehlenbeckia, which see. 



Coccoloba uvifera, the sea-grape or shore-grape of the 

 West Indies, bears an edible fruit, and has particularly 

 beautiful foliage. It is the most important of the genus 

 and is offered by dealers in tropical plants. It will not 

 stand the frost and its cultivation out-of-doors is 

 limited to the frostless region of California and Florida. 

 It can be easily grown in any greenhouse North. All 

 species are easily propagated by seeds, which are very 

 plentiful with most of the species. Some species may be 

 increased by cuttings of ripe wood, which root easily 

 in sand under the usual conditions, in a frame or prop- 

 agating-house. Layering may also be employed to in- 

 crease the stock. The various species grow naturally 

 in both clayey and sandy soils, preferring moist rich 

 earth, and a high temperature. C. uvifera frequents the 

 seashore, and is found growing in sand and broken 

 shells apparently lacking altogether in plant-food. 

 Rich sandy soil of a light character seems to be best for 

 all the species so far known in cultivation. Plants are 

 readily transplanted from the open ground, but pot- 

 grown plants are to be preferred. (E. N. Reasoner.) 



uvifera, Linn. SEA-GRAPE. SHORE-GRAPE. UVADEL 

 MAR. Fig. 1009. Tree, reaching 20 ft. or more, with 

 many flexuous branches: Ivs. large, often 5 in. long by 

 7 in. wide, broadly heart-shaped, wavy margined, 



1008. Monstrous or abnormal leaf of Cobaea. 



glossy, leathery, glabrous, the midrib red at the base; 

 petioles short, with sheathing stipules at the base: 

 racemes 6 in. long, erect in fl., nodding in fr.; fls. 1J^ 

 in. across, white, fragrant; petals 5; stamens 8; styles 3: 

 berries 9 or more in a raceme, small, about %in. long, 

 pear-shaped, reddish purple, dotted green, sweetish 

 acid: nut roundish, with a short, sharp point on top, 

 and vertical wrinkles. Sandy seashores of Trop. Amer. 

 especially S. Fla. and W. Indies. B.M. 3130. The wood 

 is used in cabinet-work, and, when boiled, gives a red 

 color.
