CERATOZAMIA 



CEKCOCABPUS 



long or more, lanceolate : cones produced annually on 

 separate plants; female cones 9-12 in. long, 4-6 in. thick, 

 the scales 2-horned ; male cones narrower, longer, on a 

 hairy stalk, the scales with two small teeth. Mex. Gn. 9, 

 pp. 308, 309.— An excellent decorative plant, best grown 

 in sandy loam. Give freely of water and heat in spring 

 and summer, but keep cooler and dryer in winter.

CEBCIDIFH'fLLirM (Cercis and pliyllonjlesd; the 

 Ivs. resemble those of Cercis). TrocJiodendr&cew. Tree, 

 with deciduous, usually opposite, petioled and palmately 

 nerved Ivs. : fls. dioecious, inconspicuous, apetalous, soli- 

 tary, staminate nearly sessile, bearing numerous stamens 

 with slender filaments, pistillate pedicelled, consisting of 

 3-5 carpels, ending in long, purplish styles and developing 

 into about %m. long, dehiscent pods, with many seeds. 

 One species in Japan. Hardy, ornamental, shrubby tree 

 of pyramidal and, when young, almost fastigiate habit, 

 with handsome, light green foliage, purplish when un- 

 folding, turning bright yellow or partially scarlet in fall. 

 It prefers rich and moist soil, and grows rapidly when 

 young. Prop, by seeds, sown in spring, and by green- 

 wood-cuttings, taken from forced plants in early spring, 

 or by layers ; cuttings from half -ripened wood m sum- 

 mer, under glass, grow also, but not very well. 



Japdnicum, Sieb. & Zuce. Bushytree, usually 20-30 ft., 

 but sometimes rising to 100 ft., with slender, glabrous 

 branches : Ivs. opposite, occasionally alternate, slender 

 petioled, cordate, orbicular or broadly ovate, obtuse, cre- 

 nate-serrate, glabrous, glaucous beneath, 2-3 in. long. 

 Japan. G.F. 7:106, 107, and G: 53. Mn. 3:7i. Gng. 5:135. 

 —A very desirable tree, one of the best of the newer 

 introductions from Japan. Alfred Eehdek. 



CfiRCIS (JS'erX;Js, ancient Greek name). Leguminbsm. 

 Judas Tree. Bed Bud. Trees or shrubs : Ivs. decidu- 

 ous, alternate, petioled, palmately nerved, entire : fls. 

 papilionaceous, pedicelled, pink or red, appearing before 

 or with the Ivs., in clusters or racemes from the old 



411. Cercis Canadensis (X/^). 



wood : calyx 5-toothed, red : petals nearly equal, the up- 

 permost somewhat smaller : pod compressed, narrow- 

 oblong, narrow-winged on the ventrical suture, many- 



seeded. Seven species in N. America, and from S. Europe 

 to Japan. Very ornamental trees or shrubs, with hand- 

 some, distinct foliage and abundant showy fls. in spring, 

 very effective by their deep pink color. They are well 

 adaped for shrubberies or 

 as single specimens on 

 the lawn, and attain rarely 

 more than 20 or 30 ft. in 

 height, forming a broad, 

 irregular head when older. 

 Only G. Canadensis is 

 hardy north, while none of 

 the others can be grown 

 successfully farther north 

 than New York. They 

 grow best in rich, sandy 

 and somewhat moist loam, 

 and should be transplanted 

 when young,as olderplants 

 can be hardly moved with 

 success. Young plants, 4 

 or 5 years old, produce fls. 

 freely and may be recom- 

 mended for forcing, espe- 

 cially C Chinensis , which 

 is the most beautiful of 

 all. Prop, by seeds, sown 

 in spring, best with gentle 

 bottom heat ; sometimes 

 increased by layers, or by 

 greenwood cuttings from 

 forced plants in early 

 spring ; O. Chinensis grows 

 also from greenwood cut- 

 tings in summer under 

 glass.

Chinensis, Bunge ((7. Japdnicd, Sieb.). Fig. 412. Tree,

 ceous, shining above, 3-5 in. long: fls. 5-8, purplish pink, 

 %m. long : pod 3-5 in. long, narrow. China, Japan. 

 F.S. 8:849. Mn.2:139. G.F. 6: 476. -The most beautiful 

 species, with the fls. nearly as large as those of G. Sili- 

 quastrum and more abundant.

 broader than long.

 fls. rose-colored, Kin. long: pod 2-2>^in. long. Calif.— A 

 closely allied species is C . renifdrmis , Engelm. (C. Tex- 

 insis, Sarg.). Small tree: Ivs. subooriaeeous, 3-5 in. 

 wide, sometimes pubescent beneath : pod 2-4 in. long.
