6, various in form, with teeth sometimes glanduliform (stipular ?) 

 interposed. Tube of long tubular-funnel-shaped or subcampanulate 

 corolla obconical, sometimes very elongate, occasionally angular, 

 glabrous or variously pilose within ; lobes of limb 4, or more rarely 5, 

 shortly 3-angular, valvate, finally recurved. Stamens inserted at 

 throat; filaments short; anthers exserted introrse versatile, 2-rimose. 

 German 2-celled; disk epigynous various; style slender, apex exserted 

 longer or shorter clavate, entire or 2-lobed. Ovules oo, inserted on 

 an ascending placenta inserted at bottom of septum and there very 

 shortly stipitate. Fruit capsular, septicidal from apex; valves 2, 

 coriaceous or parchmentlike. Seeds oo, inserted on ascending pla- 

 centas, imbricate, dilated at margin to an unequally dentate wing; 

 albumen hard; embryo straight. — Herbs, sometimes subshrubby, 

 generally slender and twining, glabrous or variously clothed ; leaves 

 petiolate, oftener ovate-acuminate ; stipules short acute ; flowers * 

 axillary solitary or variously cymose ; peduncles or pedicels oftener 

 slender, 2-bracteolate. {Trop. and suhtrop. America.^)

 or narrow suburceolate corolla 4-6, smaU, 3-angular, valvate. Stamens 

 2-morphous (in female flower sterile), inserted at bottom of corolla; 

 filaments villose, short or elongate ; anthers introrse, versatile, some- 

 times far exserted ; cells rimose, free at base. Germen 2-celled ; 

 disk epigynous thick ; branches of slender pilose style 2, acute, 

 papillose within, recurved. Ovules oo, inserted on elongate placentas 

 descending from top of cell, linear. Fruit capsular oblong, septicidal 

 from apex. Seeds oo, subpeltate fusiform ; testa reticulate much 

 produced on both sides; embryo rather long, albuminous. — Small
