EUCOMMIA (Greek, eu, well, and kommi, gum; 

 alluding to the fact that the plant contains rubber). 

 Eucommiaceas. Deciduous tree grown for its handsome 

 foliage and also for its possibility as a hardy rubber- 

 producing tree. 



Branches with laminate pith: winter-buds conspicu- 

 ous, with imbricate scales: Ivs. alternate, petioled, ser- 

 rate, without stipules: fls. dioecious, without perianth, 

 solitary in the axils of bracts at the base of the young 

 shoots and precocious; staminate fls. pedicelled; sta- 

 mens 6-10 with very short filaments and elongated 

 linear anthers; pistillate fls. short-pedicelled with a 

 1-celled, 2-ovuled stipitate ovary, bifid at the apex, the 

 lobes stigmatic on the inside: fr. a compressed winged 

 nutlet. -One species in Cent. China, not closely related 

 to any other genus; it was first placed with the 

 Trochodendracese or Magnohaceae and afterward with 

 the Hamamelidacese, but is now generally considered as 

 representing a distinct family allied to the last named. 



Eucommia is an upright-growing vigorous tree with 

 rather large elliptic dark green foliage, inconspicuous 

 precocious flowers and winged fruits; in habit and 

 foliage it resembles somewhat an elm tree. In China 

 the bark is a most valued medicine. The tree contains 

 rubber in all its parts, particularly in the young growth 

 and in the bark. Though the rubber has proved to be 

 of good quality, it is apparently difficult of extraction 

 and not present in sufficient quantity to make the 

 commercial exploitation of the tree pay; therefore the 

 hopes which have been set in this "hardy rubber tree" 



will probably never realize. The tree has proved per- 

 fectly hardy as far north as Massachusetts and grows 

 well in a loamy humid soil. Propagation is by seeds and 

 by greenwood cuttings under glass. 



ulmoides, Oliver. Tree, to 60 ft. : Ivs. elliptic to elliptic- 

 ovate, acuminate, broadly cuneate at the base, serrate, 

 glabrous, glossy and dark green above, pubescent below 

 when young, 3-7 in. long: samara oblong, bifid at the 

 apex, 1M-1H in. long. April; fr. in Oct. Cent. China.

EUCRtPHIA (Greek for well covered). Eucryphia- 

 cex; formerly referred to Rosacese, A very few southern 

 hemisphere resinous trees or shrubs, with opposite 

 evergreen simple or pinnate Ivs. and showy white fls. : 

 sepals 4, free; petals 4, broad; stamens very many; 

 ovary free, 5-18-celled: fr. a hard dehiscent caps. E. 

 pinnatifolia, Gay, is a shrub or small tree, hardy in 

 parts of England, with large white hypericum-like 

 4-petaled fls. and rose-like foliage, from Chile. B.M.

 70, p. 190; 73, p. 471. Neither of these is in the Ameri- 

 can trade. Worthy of trial in the S. There are 2 species 

 (E. Billardieri, Spach, and E. Moorei, Muell.) in Tas- 

 mania and New S. Wales. 



Plants of E. pinnatifolia give much satisfaction in 

 the open in England although not much known, the 

 pure white fls. 3 in. diam., and borne more or less in 

 pairs, being produced in great profusion in late summer; 

 it grows 8-10 ft. high. 



EUGENIA (named in honor of Prince Eugene of 

 Savoy). Myrtacese. A large group of trees and shrubs, 

 grown chiefly for their ornamental foliage and berries. 

 Many tropical species yield edible fruits which are 

 both eaten out of hand and made into jellies or con- 

 fections. A number of these have been recently intro- 

 duced into the warmer parts of the United States, 

 where they give promise of attaining much impor- 

 tance. The clove of commerce belongs to this genus. 



Evergreen trees and shrubs: Ivs. opposite, mostly 

 entire and finely penniveined: fls. white or creamy or 

 the numerous stamens yellowish : fr. a drupe-like berry, 

 usually globular or pear-shaped, 1-5-seeded. Habit 

 and infl. of Myrtus, which see for cult, and prop.
