ELffllS (Greek, olive). Palmdcem, tribe Cocolnece. 

 Tropical spineless palms with pinnate foliage, of which 

 the best known is the Oil Palm of western Africa, 

 whose red fruits, borne in large clusters, yield the palm 

 oil of commerce, which is used in making candles and 

 soap. Young plants are grown for ornament in S. Calif., 

 and under glass North. The other 6 species are from 

 tropical S, America. The genus is separated from Cocos 

 by the 1-3-seeded fruits, with 3 pores above the middle. 



Guinefinsis, Jacq. Oil Palm. Stems stout, 20-30 ft., 

 coarsely and deeply ringed : leaves 10-15 ft. ; petiole 

 spiny-serrate; leaflets linear-lanceolate, acute, the same 

 color above and below. F.S. \i:\iSi2. — Elais Giiineen- 

 sis, from an early stage in growth, is one of the most 

 ornamental palms. Until it reaches several feet in 

 height it is a slow grower, consequently we do not see

much of it, except in collections. It does best iu a 

 warm temperature, although it will thrive in an inter- 

 mediate house. Seeds are always obtainable from sev- 

 eral of the large European houses. It is but little grown 

 as a commercial palm, as young plants do not show their 

 full character. Given same treatment as Areca liife.t- 

 ceiis, will grow well. This treatment includes night tem- 

 perature of 6:3° and plenty of water.

ELm.OCkB.FTJS {(Wcv'k.oli re-fruit). Tilidcece. This 

 grnus inc'ludis a tenili-r evergreen flowering shrub of 

 very distinct ap]«Mr;iiice. The creamy white petals, 

 fluinuiugly fi iiiged. the bright red sepals and pedicels, 

 and the mass of yellow stamens are the chief features. 

 The racemes contain 2-5 pendulous flowers, which are 

 about half an inch across, and fragrant. This plant was 

 once advertised by Pitcher and Manda, and may exist 

 in a few clinic. ■ cullci i..ns. The genus has about 50 

 species, all fr.nn trii|M.al Asia, Australia and the Pa- 

 cific isles. Ill tin- tnipirs they are trees, with alternate, 

 rarely opposite lvs., which are entire or saw-toothed,- 

 and in some species sparingly spotted with black be- 

 neath : fls. axillary, in racemes ; petals glabrous or 

 silky; drupes oblong or globose. 



grandifldrus, James Smith. A much-branched shrub, 

 abinit 7 ft. bit;!! under glass: lvs. considerably clustered 

 at the enils of branches, 3-6 in. long, broadly lanceolate; 

 petiole a fourth to 1 in. long, with a few distant saw- 

 teeth, or more or less round-toothed or wavy-margined: 

 sepals 5, red outside, white inside ; petals 5. Java. 

 B.M. 4680.— Lvs. rather leathery, dark green above, 

 paler beneath. Warmhouse. Prop, by cuttings of nearly 

 ripened wood. Not common. 



E. ej/dnetis. Sims, named for its blue fruits (which are not 

 known in cultivation), has broader and less tapering lvs., with 

 more numerous teeth, and membranous texture, and the sepals 

 are white outside. Australia. B.M. 1737. ^ ]yj

ELffiODfiNDEON (Greek for o^u'f tree, from the re- 

 semblance of the fruit to that of the olive) . CelastrAcem. 

 Perhaps 40 species of shrubs or small trees in tropical 

 countries, chiefly in the Old World tropics. Lvs. simple, 

 entire or crenate, opposite or alternate, thickish, fre- 

 quently evergreen : fls. inconspicuous, greenish or white, 

 iu axillary clusters; calyx 4-5-parted; petals 4-.'>, and 

 exceeding the calyx; stamens 4-5: ovary single, sur- 

 rounded by a fleshy ring: fruit a small fleshy drupe. 

 Certain plants which, before they had bloomed, were 

 referred to Aralia, are now known to belong to this 

 genus, representing a distinct natural family. Culture 

 of Aralia. 



orientille, Jacq. (ArUia Chabriiri, Hort.). A most 

 graceful and handsome plant, with linear-lanceolate 

 alternate, shining, drooping leaves, 10-12 in. long, and 

 with a reddish rib. Madagascar, Mauritius. R.H. 1891, 

 p. 224. A.F. 10: 1041. -Holds its lower foliage well, or 

 throws out new foliage to take the place of that which 

 drops. In the early descriptions, the plant was said to 

 have pinnately compound lvs., but what were taken for 

 leaflets are really lvs. Still a rare and choice plant in 

 this country. Thrives in either an intermediate or a 

 warmhouse. Prop, by single-eye cuttings in small pots, 

 kept rather warm. See, also, p. 87. 



atiBtr&le, Vent. Int. into S. Calif, from Australia, and 

 prized for its holly-like foliage. In its native habitat it 

 is a tree .30-40 feet high, producing useful close-grained 

 wood. L, H. B.

ELECTRO-HORTICULTURE is a term used by 

 Sieiiiiiis to d.sigM:itr the application of the electrii' 

 light to the growing of plants. The term is an unfor- 

 tunate one, since the use of electric light is not an ap- 

 plication of electricity itself to plant-growing, but is 

 merely a device for securing illumination. Any strong
