 (Arabian coffee) largely cult, in S. Brazil, Java, Jamaica, and else- 

 where, often under the shade of large trees. C. liberica Hiern 

 (Liberian coffee) cult. usu. at lower elevations; its produce is not 

 so good. Other sp. nre also used. The fr. is a 2-seeded drupe, 

 resembling a cherry. The pulp and the endocarp (which covers the 

 two seeds like a layer of parchment) are mechanically removed. 

 The seed, or coffee-bean, has a deep groove on the ventral side ; 

 by soaking it in water the endosperm is softened and the embryo 

 may be dissected out. The stimulating property depends on the 

 presence of the alkaloid caffeine. Coffee cultivation was from 1850 

 to 1880 the mainstay of Ceylon agriculture, but was killed out largely 

 by the attacks of a fungus (Hemileia vaslatrix) and the green bug. 

 By far the largest cult, is that of Brazil, which in 1912 exported 

 ^45 million worth of coffee. (Raoul, Culture du Cafeier, Paris.)
