 white, pink or greenish, secund in dichotomously branched axillary or 

 terminal cymes ; bracts and bracteoles various or absent. Calyx short, 

 usually cylindric or campanulate, becoming obreniform or obcordate in 

 fruit, the lobes small and persistent. Corolla tubular or funnel-shaped, 

 the tube inside glabrous or hairy ; the lobes 5, short, valvate in bud, 

 often winged on the back, and with a fold in the sinus between neigh- 

 bouring lobes. Stamens 5, inserted on the tube ; anthers linear. Disk 

 large, fleshy, 2-lobed. Ovary 2-celled ; style filiform; stigmas 2, linear 

 or broad ; ovules numerous, inserted on placentas ascending from the 

 bases of the cells. Capsules coriaceous, compressed obreniform or ob- 

 cordate, dehiscing at the apex by 2 broad gaping valves; placentas 

 divaricating, many-seeded. Seeds minute, angled, the testa crustaceous ;
