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 

 ■»nd summer, but keep cooler and dryer in winter.

 One species in lapan Hardv ornamental shrubby tree 

 of pyiamidal and when-voung almost fastigiate habit 

 with handsome, light gr< en foliage purplish when un 

 folding, turning bright j ellow or partially scarlet m 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 in sum- 

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



Japdnicum, Sieb. & Zucc. Bushy tree, 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.

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

 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; C.(77i/HeH«!« grows 

 also from greenwood cut- 

 tings in summer under
