albuminous. — Small trees ; leaves opposite simple serrate petiolate ; 

 stipules deciduous ; capitula pedunculate (of Codia) axillary or

 sometimes empty ; style 2-fid or 2 -partite ; branches divergent, 

 stigmatose at obtuse or capitellate apex; ovules 1, 2 in each cell

 superior, finally (by torsion of funic! e) lateral extrorse. Fruit 

 capsular, coriaceous or submembranous, either 1 -celled and usually 

 indehiscent, or 2-celled septicidal ; cells often 1 or 2, aspermous, 

 filled with thickened spongy or suberous septum. Seeds smooth 

 ovate-compressed; embryo minute at apex of fleshy albumen. — 

 Polymorphous undershrubs, often heath-like ; branches subverticil- 

 late ; leaves small, often acicular linear or oblong, rigid, nearly 

 terete, rarely flat, alternate or subverticillate, lax or densely imbri-

 or more rarely in branching racemes ; bracts and bractlets 2, usually 

 sepaloid, glandular at apex, sometimes {Berardia) large coloured 

 involucrant {South Africa). See p. 381. 



S6 ? Staavia Thunb. — Flowers nearly of Brunia; petals not 

 crested. Germen altogether or partly inferior; cells 2, 1- or 2- 

 ovulate, or one effete ; style 1 , longitudinally 2-furrowed ; apex stig-
