NATURAL HISTORY OF PLANTS. 



flat, or even concave on top. The ovary always contains two colla- 

 teral ascending ovules, more or less completely anatropous, with their 

 micropyles downwards and outwards. 1 The fruit is coriaceous or 

 woody, entire or bivalved, one or two-seeded. "When there are two 

 seeds they are collateral and unsymmetrical, more flattened on the 

 side by which each touches its fellow than on the other, or edged

at the junction of the two faces by a more or less prominent or 

 fleshy rim, or a wing which may encircle the whole seed. Within 

 the seed-coats is a large fleshy exalbuminous embryo, with its 

 radicle inferior. Grcvillea consists of Oceanian trees and shrubs, 

 mostly natives of Australia. The leaves are alternate, usually per- 

 sistent, glabrous or covered with peculiar hairs," flat or cylindrical, 

 entire, or more or less incised. The flowers are but rarely solitary 

 or geminate in the axils of the upper leaves or at the end of the 

 branches. We find them far more frequently in axillary or terminal 

 simple or branched racemes. The flowers are usually paired in the 

 axil of each bract ; this is the case in about nine-tenths of the two 

 hundred known species ; 3 they are rarely solitary or fascicled.
