turbinate. Lobes of calyx 5, oftener very unequal. Corolla funnel- 

 shaped or in female flower tubular ; lobes 5, elongate, valvate, with 

 dorsal horn under apex. Stamens 5 ; anthers large exserted. Germen 

 inferior, 2-celled ; one cell sterile ; disk small ; style elongate exserted, 

 at stigmatose apex dilated incurved. Ovule in fertile cell 1, suberect ; 

 micropyle extrorsely inferior. Fruit subclavate, crowned with calyx, 

 nearly dry; putamen rugulose, 1-spermous. Seed erect, with short 

 fleshy aril at base ; embryo axile ; albumen dense fleshy. — Herbs or 

 undershrubs ; leaves opposite, narrow elongate, revolute at margin ; 

 stipules connate in a dentate-setose sheath connate with leaves ; 

 flowers axillary solitary, pedunculate or sessile. (South. Africa,'^) 



21. Otiophora Zucc.^ — Flowers 4, 5-merous ; receptacle obconical 

 or obovoid; lobes of calyx very unequal, persistent; the larger 1, 2, 

 foliaceous accrescent. Corolla hypocrateriform ; tube very slender 

 elongate ; lobes 4, 5, elongate, valvate, patent. Stamens same in 

 number, inserted in throat ; filaments very slender ; anthers elongate 

 exserted. Germen 2-celled ; style branches 2, slender exserted gla- 

 brous ; ovule in cells 1 , erect ; micropyle extrorsely inferior. Fruit 

 membranous, sub-2-dymous, crowned with unequal calyx; cocci 2, 

 solute, indehiscent. Seed erect oblong ; testa dark ; albumen densely 

 fleshy ; cotyledons of axile embryo superior foliaceous. — Herbs, some- 

 times subshrubby ; leaves (small) opposite, ovate or lanceolate ; 

 stipules connate with petioles in setose sheath; flowers in loose 

 terminal spikes, ebracteate, sometimes 2-nate. (Madagascar.^) 



22. Plocama Ait.* — Flowers 4-7-merous ; germen inferior ovoid. 

 Calyx superior, oftener 5, 6-dentate, persistent. Corolla subcam- 

 panulate, 4-7-lobed ; lobes lanceolate, valvate, inflexed at apex. 

 Stamens as many, inserted in throat ; filaments erect rather short ; 

 anthers thick introrse. Germen 2-4-celled ; disk epigynous minute ; 

 style at apex obtuse 2-4-dentate stigmatose. Ovules in cells solitary 

 erect. Fruit baccate subglobular pulpy ; seeds 2-4, erect, immersed
