Storax Family 355 



The two native species are as good or belter than any of the exotic 

 introductions. 



* H. letraptera Linn. (135) {M ohrodendron carolinum), the Four- 

 winged Silver Bell, so called from the four-winged fruit; is a large shrub, 

 growing to twenty feet, often in tree form, with a bewildering, cloudy 

 mass of snowy white; early flowers (iNIay); it is hardier than its con- 

 gener — 



* H. diptera YA\\s. (136), the Two-Winged Silver Bell, which is smaller 

 (ten feet), but has even more showy, larger blossoms and leaves; it 

 needs protection in the north. 



Stjrax and S5anplocus. Storax. Two closely allied genera of over 

 two hundred and thirty species, furnish, mainly for southern planting, 

 a few small trees and shrubs, which, because of their delicate, white 

 flowers and somewhat tropical-looking, leathery foliage, and graceful 

 habit, have ornamental value. They are best planted singly, are 

 adapted to light soils, but only half hardy. 



Styrax grandiflora Ait. (137), a shrub of five to ten feet, with large, 

 pointed leaves (two to six inches and more), S. americana Lam. (138), 

 and S. pulveridenta (139), the three native species, are of southern 

 range, and hence not very hardy, and are outdone in beauty Ijy the 

 Japanese Storax. 



5. Japonica S. & Z. (140) is a small to medium-sized tree or shrub 

 (thirty feet), with horizontal branch habit; is preferably kept in shrub 

 form to secure the best flower show, the pendulous racemes of fragrant, 

 pure white flowers, with yellow stam.ens, covering the entire length of 

 the branchlets in early summer. The leaves are small (one to three 

 inch), pointed, light green. It is hardy as far as New York City, and 

 a splendid specimen plant. 



S. Obassia S. & Z. (141), sometimes growing into a small tree, also 

 from Japan, with catalpa-like leaves (six to ten inch) is less effective. 



Symplocos tinctoria L'Hert., Sweatleaf, so called from the fragi-ance 

 of its foliage, a pretty, low shrub, sometimes tree, from the Southern 

 States, is almost an evergreen, with long narrow, somewhat leathery 

 leaves, and clusters of fragrant yellow flowers. 



5. cratcegoides Buch-Ham (143), from Japan, is the most hardy 

 of this group, a shrub (five to eight feet), sometimes assuming tree 

 form (thirty feet), resembling the hawthorn in outline, forming an 

 irregular open head with long, thick, rough leaves and panicles of fra-
