calyx, 2-sulcate, septicidal and loculicidal at conical vertex ; segments 

 4, obcuneate. Seeds oo, imbricate, catidatelj alate on both sides ; 

 albumen fleshy ; embryo minute. — An epiphyllous shrub ; leaves 

 opposite, oblong-lanceolate membranous, deciduous, petiolate; stipules 

 interpetiolar, widely ovate-acute, glandulously cihate to axils, per- 

 sistent ; flowers ^ in corymbiform cymes ; some bracts of inflorescence

 subentire or obscurely 2-lobed. Ovules oo, inserted on placentas 

 adnate to septum, ascending. Fruit capsular, subterete or oblong, 

 oftener obtuse above, loculicidal ; valves 2, finally free from placentas. 

 Seeds oo, ascending, dilated on both sides to a broadly ovate wing 

 subentire or lacerate at margin, 2-lobed below ; albumen fleshy ; coty- 

 ledons of inverted embryo flat ovate or suborbicular ; radicle inferior
