CEPHALANTHUS 



CEEASTIUM 



cult. Hardy ornamental shrub, with handsome glossy 

 foliage and very attractive with its flower balls appear- 

 ing late in summer. It thrives in any good garden soil, 

 best in a sandy, somewhat moist one. Prop, by seeds or 

 by cuttings of ripened wood in fall, and also by green- 

 wood cuttings taken from forced plants early in spring. 

 ocoidentUis, Linn. Shrub, 3-12 ft. : Ivs. long-petioled, 

 ovate or oval, acuminate, glossy above, glabrous or 

 slightly pubescent below, 3-6 in. long : heads about 1 in. 

 in diam., long-peduncled, 3 or more at the end of the 

 branches. July-Sept. Prom New Brunswick south, 

 west to Ontario and Calif . Em. 394. R.H. 1889, p. 280.— 

 Var. augustifolia, Andr^. Lvs. oblong, lanceolate, usu- 

 ally in 3's. R.H. 1889, p. 281. Alfred Rehdeb. 



CEPHALABIA (Greek for head, alluding to the capi- 

 tate flower-clusters). Dips&cem. Coarse annual or per- 

 ennial herbs of Europe, Africa and Asia, much like 

 Dipsaeus, but the heads less spiny. The heads are ter- 

 minal and globular, bearing many 4-parted yellowish, 

 whitish or bluish florets. 



TatArica, Schrad. Perennial, 6 ft,, rank, with striate 

 stems, suited to the rear border, where strong effects are 

 desired, with showy cream-white flat heads in July and 

 Aug. : lvs. pinnate, the Ifts. broad -lanceolate and ser- 

 rate. Grows readily, and is increased by seed or divid- 

 ing the clumps. L. jj. B. 



CEFHALOIAXUS (Greek, head ; Taxus-like plant, 

 with fls. in heads or clusters ) . Coniferm, tribe Taxdce<E. 

 Trees or shrubs, with evergreen, linear, pointed lvs. 

 with 2 broad, glaucous lines beneath, arranged in 2 

 rows: fls. dioecious, staminate in 1-8-fld., short-stalked 

 clusters, pistillate consisting of a small cone with sev- 

 eral bracts, each bearing 2 naked ovules. Seed enclosed 

 in a fleshy envelope, drupe-like, about 1 in. long, reddish 

 or greenish brown. Prom allied genera it may be easily 

 distinguished by the resin-canal in the center of the 

 pith, and by the glaucous lines beneath from Taxus, 

 which has the lvs. yellowish green beneath, and from 

 Torreya by the glaucous lines being broader than the 3 

 green lines, while in Torreya the glaucous lines are 

 narrower than the green ones. Six closely allied spe- 

 cies from Himal. to Jap. Ornamental evergreen shrubs, 

 in appearance very like a yew, but of more graceful 

 habit. Not hardy north, or only in very sheltered posi- 

 tions. They thrive best in a somewhat moist but well- 

 drained, sandy loam, and in partly shaded situations. 

 Prop, by seeds, stratified and sown in spring; imported 

 seeds usually do not germinate until the second year ; 

 increased also by cuttings in August, under glass, and 

 by veneer-grafting in summer, on one of the species or 







409. Cepnalotus tollicularis (XK). 



on Taxus baccata. For cions and cuttings, terminal 

 shoots should be selected, which form regular plants 

 with whorled branches like seedlings, while cuttiuga 

 from lateral branches grow into irregular, low, spread- 

 ing shrubs. 



A. I/us, S-S in, long : branchlets yellowish green, 

 pendulous. 



F6rtunei, Hook. Lvs. tapering gradually into a sharp 

 point, usually falcate, dark green and shining above : 

 fr. greenish brown, obovate. N. China, Jap. B.M. 4499. 

 P.S. 6: 555. R.H. 1878, p. I17.-This is the most grace- 

 ful species, with long and slender branches, attaining in 

 its native country 50 ft. in height, in culture usually re- 

 maining a shrub. 



AA. Ia!S. 1-^ in. long. 



pedunouiata, Sieb. & Zuco. With spreading, often 

 somewhat pendulous branches, dark green when young: 

 lvs. to 2 in. long, narrowed into a sharp point, shining 

 and dark green ai)ove : fr. ovoid, rounded at both ends, 

 rarely globulat. Jap., China. G.C. III. 18: 716. -In 

 Japan, tree to 25 ft. high, usually shrub in culture. A 

 remarkable form is var. fastigi&ta, Carr. (Podocdrpus 

 • Koraidna, Sieb. & Zucc. ), of columnar habit, with up- 

 right branches and spirally arranged lvs. G.C. II. 

 21:112. S.H. 2:450. Gng. 2:341. 



drupilcea, Sieb. & Zucc. Branches spreading, stiff, 

 usually light green when young : lvs. about 1 in. long, 

 abruptly pointed, narrow and straight, often upturned: 

 fr. usually obovate, narrowed at the base. Jap. G.C. 

 III. 18:717.— This is the dwarfest species-, usually form- 

 ing a low bush with stiff, spreading branches.

CEFHALdTUS (Greek, in a head, referring, to the 

 crowded stamens). Saxifrag&ce(e. One species in 

 Australia. Lvs. all radical, of two kinds, the ordinary 

 foliage lvs. being spatulate or elliptic, hairy, and entire, 

 the others being pitchers with purple tints and a netted 

 and veined lid. The fls. are borne in an interrupted 

 spike, on an erect scape ; they are apetalous, and have 

 a white, 6-parted calyx, 12 stamens in two sets, and 6 

 1-seeded carpels. The species is C. follicul^ris, Labill. 

 (Pig. 409). It is cult, in ooolhouses for its odd insec- 

 tivorous pitchers, which are 1-3 in. long and beautifully 

 lined and shaded with purple and green. The plant is 

 grown in peat and moss, after the manner of Drosera 

 and Dionsea. Delights in plenty of moisture, mounted 

 on sphagnum moss. Give a cool and shady position. 

 Prop, by seeds (allow only one seed vessel to mature) 

 and also by division. A most interesting plant. R.B.

CERASTIUM (Greek for horn, alluding to the shape 

 of the pod). Caryophylldcew. Decumbent annuals or 

 perennials, with weak, slender stems, small, opposite 

 lvs. and small white fls. : differs from Arenaria in the 

 shape and dehiscence of the capsule: sepals 5 or 4; 

 petals as many, often 2-cleft; stamens 10 or less. Valu- 

 able in rockeries or for bedding and borders. Species 

 about 100, of world-wide distribution.

 branched and matted; stems 8-12 in. long; lvs. oblong or 

 lanceolate, pale green, pubescent, obtuse, }^-lK in. long, 

 }i in. wide: fls. very numerous, appearing In April and 

 May ; petals 5, deeply bifld ; capsules twice as long as 

 the calyx. On magnesian rocks, N. Y. to Va. and west- 

 ward. Bui. 74, Ind. Agr. Exp. Sta., from which Pig. 410 

 is adapted.— Recommended as a bedding plant, for its 

 mat-like habit, covered with white bloom.

 grandifldrum, Waldst. & Kit. Creeping perennial :
