CEEATIdLA (Greek, a little horn, referring to the 

 4-branched, serrate stigma). Umpetrdcew. A heath- 

 like evergreen, much-branched shrub from the sand 

 barrens of Ga. and S. C. ; rarely cult. N., but not hardy. 

 Only 1 species. 



ericoldes, Michx. Height 2-8 ft. : branches subverti- 

 cillate, marked with scars of numerous fallen Ivs., the 

 younger and upper ones only retaining foliage : Ivs. 

 crowded, almost whorled, }4-/4 in. long, linear, rigid, 

 shining, pale, rounded above, grooved beneath: fls. in- 

 conspicuous, dioecious, of peculiar structure : berries 

 round, orange-yellow. B.M. 2758. 



CEBATOLOBUS (Greek for homed pod). Palm&cem. 

 Spiny Javanese palms, with pinnate Ivs., sometimes 

 seen in fine collections, but not in the Amer. trade. 

 The species are C. c6ncolor, Blume ; C. glauciscens, 

 Blume; C. JlficJjoJiteJdma, Hort. G.C. III. 23:251; C. 

 Findleydnus, Hort., A.G. 15:169. Treated the same as 

 Calamus. 



A small genus of warmhouse palms, natives of Java 

 and Sumatra. The members of this genus are slender- 

 growing, spiny palms, with pinnate leaves, one of the 

 best being O. Mieholitsiana, which has rather short 

 pinnsB irregularly grouped along the rachis. A shaded 

 house, with a night temperature of 65° to 70°, a moist 

 atmosphere, and plenty of water at the root, are the most 

 essential points in their culture.

CEEATONIA (Greek for horn, in reference to the 

 large pod). Leguminosm. A tree of the Mediterranean 

 basin, belonging to the Cassia tribe. The petals are 

 wanting; stamens 5 ; pod long, filled with a pulpy sub- 

 stance. C. Siligua, Linn., the only species, is now 

 widely distributed in warm countries, being grown both 

 for shade and for the edible pods. It reaches a height 

 of 40-50 ft. It is evergreen. Lvs. pinnate, shining, the 

 If ts. oval and obtuse. It thrives well in S. Calif, and S. 

 Pla. The pulp about the seeds is sweet and edible, but 

 the fruit is used chiefly for feeding stock. In Europe 

 these pods are much prized for the fattening of swine. 

 The dry pods are occasionally seen in the fruit stands 

 in northern markets. Var. longlssima difliers only in 

 having very long pods. The Ceratonia is known as Al- 

 garoba, Carob, Karoub, Caroubier, and St. John's Bread. 

 The last name records the notion that the seeds and 

 sweet pulp are respectively the locusts and wild honey 

 which St. John found in the wilderness. The dry 

 valves or pods have been supposed to be the husks 

 which became the subsistence of the prodigal son. See 

 G.F. 3:318, 323. L. H. B. 



CEEATOPTEEIS (Greek, horn fern). Oeratopteri- 

 dAcece. A genus of aquatic tropical ferns, forming the 

 type of a distinct family. The plants root in mud, and 

 the sterile lvs. either float on the surface or are carried 

 above the surface of the water. The sporophylls are bi- 

 tripinnate, with pod-like ultimate segments, entirely 

 unlike the sterile lvs. Only a single species is known. 

 C. thalictroldes, Brongn. Tropical waters of both hemi- 

 spheres, rare in Florida.— Useful in ponds and aquaria. 

 Must be taken indoors on approach of cold weather. 

 Best grown when planted in loam and leaf -mold topped 

 with spagnum, and tied in a pan or crib and set into a 

 tub in medium temperature, with the crown on top of 

 the water. To propagate, pull out several of the center 

 leaves, and new crowns will form; these can be divided.

CEEATOSTlGMA (Greek, ftoj-ned stigma). Phmbagi- 

 ndcem. Different from Plumbago in having no glands 

 on the calyx, stamens adnate to the corolla tube, fls. in 

 dense clusters rather than spicate, and other technical 

 characters. There are 3 or 4 species in warm regions of 

 the Old World. Herbs or sub-shrubs, with alternate, obo- 

 vate lvs. and blue or rose-red fls. 



plimibaginoides, Bunge {Plumbdgo Ldrpentm, Lindl. 

 Valor&dia plumbaginoldes , Boiss.). Perennial herb, 

 6-12 in., the stem red and branchy: lvs. entire, strongly 

 ciliate on the edges : fls. slender-tubed, with a wide- 

 spreading, deep blue limb, the 5-lobes minutely toothed, 

 collected in dense heads or umbels. China. B.M. 4487. 

 F.S. 4: 307.— A hardy bedding plant, producing prof usely 

 of its deep blue fls. late in fall. Very valuable. Needs 

 covering in winter in the N. ^ H. B 



CEEATOTHfiCA {Greek for homed capsule). Pedalid- 

 eece. Tropical African herbs of 3 or 4 kinds, with usually 

 opposite lvs. which are ovate, 5-parted calyx, 2-lipped 

 corolla, fls. solitary in the axils, and a 2-horned capsule. 

 C. triloba, Meyer, is occasionally grown in S. Fla., and it 

 may be adapted to glasshouses. It is a tall herb (5 ft.), 

 with the habit of foxglove, probably biennial, hairy: lvs. 

 stalked and crenate-dentate : fls. 3 in. long, blue, pubes- 

 cent, deflexed, the lower lobe prolonged. Handsome. 

 B.M. 6974. 



CEEAIOZAMIA (Greek, homed Zamia ; referring to 

 the homed scales of the cones, which distinguish this 

 genus from Zamia). Gycaddcew. Handsome Mexican 

 foliage plants, with Cycas-like lvs., but less commonly 

 cultivated in American palm-houses than Cycas. Best 

 raised from young imported plants, but rarely prop, by 

 seeds, or by offsets from the slow-growing trunk. Bum 

 out the center of the plant with a hot iron, and a num- 

 ber of offsets will spring from the trunk and the crown ; 

 these may be used for propagation. 



Mexic&na, Brongn. Trunk thick, short, covered with 

 the remains of fallen leaf -stalks : lvs. rich, dark green, 

 pinnate, on prickly petioles 5-6 in. long, which are 

 shaggy when young ; leaflets very numerous, 6-12 in.
