times 3- or generally 2-celled ; ovule in cells solitary descending 

 elongate, often pointed below; funicle sometimes rather long con- 

 tinuous with dorsal raphe : micropyle introrsely superior. Fruit oblong 

 or obovoid laterally compressed, crowned with calyx, generally obtusely 

 costate, slightly fleshy ; cocci indehiscent, often finally pendulous from 

 columella ; albumen of elongate seed often thin ; radicle of straight 

 embryo elongate superior. — Trees or shrubs, erect or sarmentose ; 

 ramules sometimes spinescent ; leaves opposite or more rarely closely 

 packed, petiolate, oblong or ovately elliptical, sometimes small or few ; 

 stipules interpetiolar, often 3 -angular, sometimes very small ; flowers ^ 

 in compound corymbiform and cymiferous generally terminal, 

 sometimes few flowered racemes, often bracteolate. {Both trap,

61 ? Placocarpa Hook, f.^ — Flowers (nearly of Scolosanthus) 4- or 

 more rarely 5-merous ; sepals linear-subspathulate coriaceous, per- 

 sistent. Lobes of narrow funnel-shaped slightly incurved corolla 

 obtuse imbricate ; throat glabrous. Stamens 4, 5, inserted in throat, 

 enclosed ; anthers oblong. Grermen 2-celled ; branches of slender 

 style 2, recurved stigmatose; disk depressed subentire or 2-lobed. 

 Ovules solitary descending ; funicle rather long continuous with dorsal 

 raphe. Fruit subelliptical, compressed contrary to septum ; cocci 2, 

 indehiscent ; seeds compressed . . . ? — A branched puberulous shrub ; 

 leaves small opposite, oblong or obovate, shortly petiolate ; stipules 

 small interpetiolar, 3-angular, often dark-apiculate ; flowers axillary 

 solitary, 2 -bracteolate, or 2, 3, cymose.'* (Mexico.^) 



62. Erithalis P. Br.® — Flowers 5-10-merous; receptacle sub-
