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

 warm temperature, although it will thrive in an inter- 

 )iu'iliate house. Seeds are always obtainable from sev- 

 er;d of the large Eur.ipean houses. It is but little grown 

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

 full character. Given same treatment as Areca httes-

 pel iture of G5° and ])lenty of water.

EL.ffiOCARPUS (Greek, o?/('('-/"rHi7). TlUacece, This 

 ., 1 IS iiiidudes a tender evergreen flowering shrub of 

 \ i\ distinct appearance. The creamy white petals, 

 li umingly fringed, the bright red sepals and pedicels, 

 md the mass of yellow stamens are the chief features. 

 The racemes contain 2-5 pendulous flowers, wdiich are 

 d out ludf an inch across, and fragrant. This plant was 

 u e advertised by Pitcher and Manda, and may exist 

 in I few choice c'oUecdions. The genus has about 60 

 species, all from tropical Asia, Australia and the Pa- 

 I ifac isles. In the tropics they are trees, with alternate, 

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

 and i'n some species sparingly spotted with black be- 

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

 silk}': drupes oblong or globose. 



grandifldrus, James .Smith. A much-branched shrub, 

 about 7 ft. high under glass : lvs. considerably clustered 

 at the ends of branches, 3-G 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. iGSO.- Lvs. rather leathery, dark green above, 

 paler lieneatli. Warmhonse. Prop, by cuttings of nearly 

 ripened wood. Not common. 



E. ci/aneas, Sims, nanie<l 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. 17:i7. "w^, j^jr.

ELaiODEKDRON (Greek for olive tree, from the re- 

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

 Perhaps 40 species of shrubs or small trees in tropical 

 countries, chiefly in the ( )[d World tropics. Lvs. simple, 

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

 ([uently evergreen : lis. inconspicuous, greenish or white, 

 in axillary clusters; calyx 4-5-parted; petals 4-5, and 

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

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

 Certain plants whiclt, before they had bloomed, were 

 referred to Aralia, n.re now^ known to belong to this 

 genus, representing a distinct natural family. Culture 

 of Aralia.

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