CEDRELA 



CEDRUS 



Ailanthus. 

 Cedrela on the right (X %). 



A. Lfts. 10-25, quite glabrous. 



Sinensis, Juss. Fig. 391. Tree, to 50 ft.: Ivs. long- 

 petioled, 10-20 in. long ; Ifts. 10-22, oblong or oblong- 

 lanceolate, acuminate, slightly and remotely serrate, 

 4-8 in. long : fls. white, in very long, pendulous ra- 

 cemes : fr. oblong or obo- 

 vate, about 1 in. long. June. 

 China. R.H. 1891, p. 574-75, 

 and 1875, p. 87. Gng. 4:1.- 

 Ornamental tree, with large, 

 feathery foliage ; very valu- 

 able for avenues ; similar to 

 Ailanthus, and nearly of the 

 same hardiness, but of more 

 regular and dense growth, 

 and without the disagreeable 

 odor when flowering. Ailan- 

 thus can be easily distin- 

 guished by the few coarse 

 teeth near the base of the 

 Ifts., each bearing a large 

 gland beneath (Fig. 391). 



serrata, Royle. Tree, to 

 70 ft. : Ivs. usually odd-pin- 

 nate, 15-20 in. long ; Ifts. 

 15-25, ovate-lanceolate or 

 ovate-acuminate, irregularly 

 serrate, glaucous beneath: 



391. Leaflets of Cedrela and panicles long, pendulous : 

 fls. fragrant. Himalayas. 

 This is probably the hardi- 

 est of the tropical species. 

 Closely allied to this species is C. Toona, Roxb., from 

 E. India, but Ivs. abruptly pinnate, and Ifts. usually 

 entire. 



Odorata, Linn. Tree, to 80 ft. : Ivs. 10-20 in. long; Ifts. 

 12-20, ovate-lanceolate, acuminate, nearly entire, 4-6 in. 

 long: panicles shorter than the Ivs.: fr. oblong, almost 

 1% in. long. W. India. The cedar wood comes mostly 

 from this species. 



AA. Lfts. 6-10, finely ciliate. 



Dugesi.Wats. Tree: Ivs. 10-15 in. long; Ifts. cuneate, 

 ovate-lanceolate, long and slender acuminate, nearly 

 entire, shining above, 4-6 in. long: panicles rather com- 

 pact, much shorter than the Ivs. Mexico. 



ALFRED REHDER. 



CEDKONELLA (a little Cedar, from the odor of C. 

 triphylla, a species from the Canary Islands, sometimes 

 called "Balm of Gilead"). Labiatce. Eight species of 

 herbs or shrubs, allied to Dracocephalum. The two na- 

 tive kinds described below are compact, free-flowering 

 border perennials, with aromatic Ivs. and numerous 

 showy, purplish pink fls. with blue stamens, and borne 

 in dense whorls on long racemes or spikes. They are 

 not quite hardy north, and should have a sheltered, 

 sunny position, or some winter protection. 



cana, Hook. Height 2K-3 ft.: stems hard, square, 

 subshrubby: branches numerous, especially at the base, 

 opposite, hoary with a minute pubescence: upper Ivs. 

 small, K-1K in. long, entire, hoary, numerous near the 

 fls., ovate ; lower Ivs. larger, cordate-ovate, dentate- 

 serrate : spikes numerous : whorls dense, 15 or more 

 fld. : corolla 1 in. long, limb 5-cleft, the lowest lobe 

 largest, crenate, revolute. June-Oct. Mex. and N. Mex. 



Mexicana, Benth. (Gardbquia betonicoldes , Lindl.). 

 Height 1-3 ft.: root creeping: Ivs. l%-2% in. long, 

 ovate-lanceolate (the lower ones cordate), crenate-den- 

 tate, becoming purplish below, petioled : fls. very like 

 above, bright pink. Mex., Mts. S.Ariz. B.M. 3860.- 

 Rarer in cult, than above. Lvs. larger, longer and fewer. 



triphylla, Moench (Dracocephalum Cana+iense, Linn.). 

 BALM OF GILEAD. Shrubby: leaflets 3, oblong or lanceo- 

 late : fls. purple or white, in loose spicate whorls. Aro- 

 matic plant from Canary Is. Three to 4 ft.

CEDRUS (Kedros, ancient Greek name). Coniferce. 

 CEDAR. Large evergreen trees, with quadrangular, stiff, 

 fasciculate Ivs.: fls. monoecious, forminir cylindrical cat- 

 kins: cones ovate, 3-5 in. long, with iiroad, closely imbri- 



cate bracts, attaining maturity in two or three years ; 

 seeds winged. Three closely allied species in N. Africa, 

 Asia Minor and Himalayas. Large ornamental Conifers, 

 with wide-spreading branches, very distinct in habit 

 from most other Conifers ; not hardy north, but the 

 hardiest, C. Atlantica, may be grown as far north as 

 New York in sheltered positions, while C. Deodara can 

 be only grown safely in Calif, and S. states. The very 

 durable and fragrant wood of all species is highly 

 valued. The Cedars prefer well-drained, loamy soil, 

 and will also grow in sandy clay, if there is no stagnant 

 moisture. Prop, by seeds, sown in spring ; the varieties 

 by veneer grafting, in late summer or in fall, on seed- 

 lings of C. Atlantica; or, in warmer regions, on G. 

 Deodara ; they grow also from cuttings, if the small 

 shoots are selected which spring occasionally from the 

 old wood. Plants of this genus are the true Cedars ; 

 but trees of other genera are often called Cedar. See 

 Chamcecyparis, Juniperus, and Thuya; also Cedrela. 



A. Branches stiff, not drooping : cones truncate, 

 and often concave at the apex. 



Atlantica, Manetti. Fig. 392. Large, pyramidal tree, 

 to 120 ft., with upright leading shoots : Ivs. mostly less 

 than 1 in. long, usually thicker than broad, rigid, glau- 

 cous-green : cones 2-3 in. long, light brown. N. Africa. 

 Gng. 2: 163. G.F.9:417. R.H. 1890, p. 32. Var. glauca, 

 Hort. Foliage glaucous, with silvery hue ; a very de- 

 sirable and vigorous form. Var. fasti giata, Carr. Of 

 upright columnar habit. R.H. 1890, p. 32. 



Libani, Barr. Large tree, with wide spreading, hori- 

 zontal branches, forming a broad head when older, lead- 

 ing shoot nodding : Ivs. 1 in. or longer, broader than 

 thick, dark or bright green, sometimes bluish or silvery: 

 cones 3-4 in. long, brown. Lebanon, Taurus, S. Ana- 

 tolia and N. Africa. Gng. 5:65. Mn.l:39. G.F.8:335. 

 Gn. 48, p. 237. Var. argentea, Loud. With blue or sil- 

 very hue. Var. nana, Loud. Dwarf form. 



392. Cedrus Atlantica. 



AA. Branches and leading shoot pendulous : 



cones obtuse. 



Deodara, Loud. Tall tree, of pyramidal habit, to 150 

 ft.: Ivs. 1-2 in. long, dark bluish green, rigid, as thick 

 as broad : cones 3%-5 in. long, reddish brown. Himal.
