Caryoear (Saouari) glabrum. 



ments, folded and contorted in the bud (fig. 282), become free, and 

 exserted, each supporting 1 a two-celled, introrse anther, dehiscing 

 by two longitudinal clefts. The gymeceum is free, superior, formed 

 of an ovary generally quad- 

 rilocular, 2 surmounted by 

 four styles, long and thin, 

 the tapering extremity being 

 stigmatiferous. In the in- 

 ternal angle of each cell a 

 descendent incompletely ana- 

 tropal ovule is inserted, 3 with 

 the micropyle directed up- 

 wards and outwards. The 

 fruit is a drupe, the more or 

 less fleshy mesocarp (fig. 285) 

 enveloping some stones, four 

 in number, generally thick 

 and solid, 4 smooth or rugose 



without, sometimes covered with prickles or sharp, rigid hairs, pene- 

 trating the softer layer which surround them, and round which is 

 often found a layer of a resinous or buty- 

 rous substance. Each stone contains a 

 seed, enclosing under its thin and glabrous 

 coats a large fleshy, oily, macropodal em- 

 bryo, almost the whole mass of which is 

 constituted by an enormous, swollen ra- 

 dicle with superior apex, while the tigella 

 folded on the radicle and surmounted by 

 two small incumbent cotyledons only oc- 

 cupies a very minute portion of the in- 

 ternal and inferior angle of the seed. 

 Seven or eight species 5 of Caryoear are

 Embryo. 



1 The most interior are said to be sometimes 

 short and antherless. 



2 There are sometimes three, five, or six 

 cells. 



3 It is often attached to the placenta at the 

 middle of the height of its internal angle, and 

 often even lower, its hilum being very near the 

 region of the chalaza, so that it resembles the 

 almost orthotropal arrangement of that of An- 

 Ihodiscus. 



4 When there are several they are unsymme- 

 trical, their internal angle being cut straight, or 

 slightly concave, and representing a kind of 

 linear cicatrice, by which it is applied against the 

 central columella.
