ERYTHRINA VESPERTILIO. Bat's-wing coral. Small, 



ornamental, leguminous tree, 30 to 40 feet high. Sometimes culti- 

 vated as a shrub in warm houses for its showy racemes of red flowers 

 and long pods with large red seeds, resembling the better-known 

 coral beans (Eryihrina spp.). Native of Australia, where the aborig- 

 ines use the exceedingly light spongy wood for making their hiela- 

 mans, or shields. 



41324. ESCALLONIA sp. From O. F. Cook, Pinasniocj, Peru. 

 A fine-leafed tree, comparable to boxwood in foliage, but with more 

 open habit of growth, often giving an effect like some of the dwarf 

 Chinese evergreens. Foliage is dark, shiny green. The tree endures 

 cutting back to any extent. Propagated by cutting and layering. 

 May thrive well along California coast, and might become popular 

 as a hedge plant or as an ornamental when space is limited. 



38713. EUCALYPTUS CLADOCALYX. From Angeles Na- 

 tional Forest, Cal. Presented by the Forest Service. A symmetrical, 

 erect Australian eucalypt, ranging in height from 50 to 100 feet. 

 The trunk is continually left smooth by the flaking off of the outer 

 bark. Timber very durable under ground and suitable for posts, 

 railway ties, etc. 



38725. EUCALYPTUS LONGIROSTRIS. From United States 

 Forest Service, Angeles National Forest, Cal. A red gum. A leading 

 forest tree of Australia, with variable habit, but up to 100 feet in 

 height, with trunk diameter said to reach 12 feet. The timber is con- 

 sidered very valuable by the Australians; in America, used for posts 

 and fuel largely. The wood is a rich red color when freshly cut, 

 growing darker on exposure to the air. It is also a good honey- 

 yielding tree. Prefers river bottoms. 



38722. EUCALYPTUS POLYANTHEMOS. From United States 

 Forest Service, Angeles National Forest, Cal. A handsome shade 

 tree of medium size, spreading habit, and slow growth. It thrives 

 under a great variety of climatic conditions. The timber is very hard, 

 strong, and durable, highly valued in Australia for railroad ties, cogs, 

 and parts of wheels. It also makes an excellent fuel, and can be used 

 satisfactorily for windbreaks. 



EUCOMMIA ULMOIDES. Deciduous tree, closely related to 

 the Hamamelidacese (witch-hazel family), with leaves and bark con- 

 taining a remarkable substance resembling rubber, which is being 

 investigated to ascertain its possible economic value. In habit and 

 foliage it somewhat resembles an elm. Hardy as far north as Bos- 

 ton. Recommended as an interesting park tree.
