 Zucc.). Fig. 893. Densely branched, bushy tree or 

 shrub, with spreading, feathery branchlets: Ivs. linear, 

 spreading, glaucous above, silvery below. A very dis- 

 tinct and beautiful variety. S.Z. 123. R.H. 1869, p.

 G.C. III. 51:132, 133. Recently intro. into England, but prob- 

 ably tender. ALFRED REHDER. 



CHAM-flJDAPHNE (chamai, dwarf, and daphne, the 

 laurel in ancient Greek, alluding to its dwarf habit and 

 evergreen leaves) . Syn., Cassandra. Ericacese. LEATHER- 

 LEAF. Small plant, rarely cultivated for its early white 

 flowers and evergreen foliage. 



Low shrub, with evergreen alternate small Ivs.: fls. 

 nodding in terminal leafy racemes; calyx small, 5- 

 lobed; corolla urceolate-oblong, 5-lobed, with 5 included 

 stamens; anthers 2-pointed: fr. a depressed-globose, 

 5-lobed caps, with numerous seeds. One species in the 

 colder regions of the northern hemisphere. Low, hardy, 

 ornamental shrub, valuable for the earliness of its 

 pretty white fls. It thrives best in a peaty and sandy, 

 moist soil. Prop, by seeds sown in sandy peat, only 

 slightly or not covered, and kept moist and shady; also 

 by layers and suckers and by cuttings from mature 

 wood in late summer under glass.

 branches, 1-3 ft.: Ivs. short-petioled, oblong, obtuse, 

 slightly serrulate and revolute at the margins, dull 

 green above and rusty-lepidote beneath: fls. short- 

 peduncled, nodding; corolla white, oblong, about ^in- 

 long. B.M. 1286. L.B.C. 6:530; 15:1464; 16:1582.

at the margin. 

 Var. nana, Rehd. 

 (Andrdmeda caly- 

 culata var. nana,

 nioides, Hort.). 

 One foot or less 

 high, with hori- 

 zontal branches. 

 L.B.C. 9:862. 

 Handsome little 

 shrub, well suited 

 for borders of 

 evergreen shrub- 

 beries and for 

 rockeries.

894. Chamaedaphne calyculata. 



CHAM^DOREA (Greek, dwarf and gift). Palmacese. 

 Spineless, erect, procumbent or rarely climbing usually 

 pinnatisect or pinnate palms. 



Trunks solitary or cespitose, slender or reed-like: Ivs. 

 simple, bifid at the apex or variously equally-pinnati- 

 sect; lobes broad or narrow, straight or oblique, acumi- 

 nate, plicate-nerved, usually callous at the base, the 

 basal margins folded back or recurved; petiole usually 

 cylindrical; sheath tubular, oblique at the throat: 

 spadices among or below the Ivs., simple or paniculately 

 branched; spathes 3 or many, often appearing much 

 below the Ivs., alternate, sheathing, elongated, split 

 at the apex, membranous or coriaceous, usually per- 



sistent; pistillate fls. very small, solitary, in small pits 

 in the spadix: fr. small, of 1-3 globose or oblong- 

 obtuse carpels, coriaceous or fleshy. Species about 60. 

 Mex. to Panama. G.C. II. 23:410, and Dammer's 

 articles inG.C. III. 

 38:42-44 (1905), 

 and 36:202, 245 

 (1904). 



Peat or leaf- 

 mold, loam and 

 sand in equal 

 parts, with a little 

 charcoal added, 

 form the best soil. 

 The species com- 

 mon in cultiva- 

 tion are quick- 

 growing. They 

 are well suited for 

 planting out in 

 greenhouse bor- 

 ders. The sexes 

 are on different 

 plants; therefore 

 several should be 

 planted in a group 

 if the handsomely 

 colored fruit is 

 desired. All of the kinds require warm temperature in 

 winter. Increased from seeds. Of the many species, 

 only a few appear in the American trade. (G. W. 

 Oliver.)
