much of it, except in collections. It does best in 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 Arern Itttes- 

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

 perature of 6.">° and plenty of water.

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

 referred to Aralia, are now known to belong to this 

 genus, representing a distinct natural family. Culture

ELffilS (Greek, olive). Palmdceie, tribe Cocolnem. 

 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 miihlle.

ELECTRO-HORTICULTURE is a term used by 

 Siemens to designate the application of the electri.- 

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

 tunate one, since the use of electr.c light is not an ap-
