ERYTHRINA VESPERTILIO. Bat's-wing coral.  Small,
ornamental, leguminous tree, 30 to 40 feet high.  Sometimes cultivated 
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 (Erythrina spp.). Native of Australia, where the aborigines 
use the exceedingly light spongy wood for making their 
hielamans, 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 National 
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 
considered 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 Hamamelidaceæ (witch-hazel family), with leaves and bark 
containing 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.
