28, SILVIANTHUS, Hook./. 



A glabrous branched shrub. Leaves broad, irregularly toothed ; stipules 0; 

 Flowers rather large, purplish, in subsessile dense-flowered opposite axillary 

 cymes ; bracts oblong, obtuse. Calyx-tube obconic ; lobes 5, rarely 4, subfolia- 

 ceous, unequal, enlarging after flowering, persistent. Corolla funnel-shaped, 

 tube hairy within ; lobes 5, short, orbicular, papillose, induplicate-valvate with 

 plaited sinuses. Disk large, conic. Stamens 2 in the corolla-tube, filament* 

 short ; anthers linear-oblong. Ovary 2-celled ; style long, stigma spindle-shaped ?

29, 1VIUSSJENDA, Linn. 



Shrubs or undershrubs, rarely herbs, erect or climbing. Leaves opposite or 

 3-nately whorled ; stipules solitary or in pairs between the petioles. Flowers 

 yellow scarlet or rarely white, in terminal cymes ; bracts and Ibracteoles decidu- 

 ous. Calyx-tube oblong or turbiuate ; lobes 6, usually deciduous, one frequently 

 forming a large petioled white or coloured leaf. Corolla tubular, funnel-shaped- 

 above, tube usually silky, throat villous ; lobes 5, valvate in bud with everted 

 margins. Stamens 5, on the throat of the corolla or lower down, filaments very 

 short ; anthers linear. Ovary 2-celled ; style filiform, stigmas 2 linear ; ovulea 

 numerous, on peltate fleshy placentas. Berry fleshy and areolate at the top, 

 many-seeded. Seeds minute, testa pitted ; embryo minute, in dense fleshy 

 albumen. DISTKIB. Species about 40, tropical African, Asiatic, and Polynesian. 



It is a -very difficult thing to assign limits to the species of this genus, and more 

 80 to define them. 



* Flowers solitary ; calyx-teeth all similar, none white and leaf-like.
