and somewhat scabrid : the pollen is compressed, 3-gonous, 

 with a small rounded lobe at each angle, from which 3 con- 

 vergent lines meet in the centre : the ovarium is supported 

 upon a short, distinct, but somewhat slender column, which 

 m many species is somewhat glandular, and this is sur- 

 rounded by the persistent base of the corolla, which inva- 

 riably breaks off as it falls, by a horizontal line, leaving a 

 cylindrical cup : the ovarium is divided into 2 cells by a dis- 

 sepiment, which presents in its centre a thickened placenta- 

 tion, and upon this are suspended, by a short ligular strap, 

 upon their ventral faces, a small number of ovaria in each cell : 

 the style is filamentous, glabrous, and of the length of the 

 tube of the corolla : the stigma is capitate, being formed of 

 2 lamellar lobes, whose inner surfaces are covered with a 

 thick green glutinous exudation : the berry is oval, scarcely 

 fleshy, and each cell presents 4 ripened seeds : these are 

 somewhat obovate, rounded on the outside, and angular on 

 the inner face, a little above the centre of which is the hilum, 

 from which the seed is suspended by its short ligular strap : 

 the testa is of a dark green colour, of very soft texture when 

 fully ripe : the albumen is soft and fleshy, in the centre of 

 which is seen the erect embryo, which is white, and as in 

 m ost other Cestrinece, lays longitudinally across the hilum, 

 the cotyledons are small, flat, and rounded, two-thirds of the 

 length and twice the breadth of the terete radicle, which
