Calyx-tube carapanulate in flower, globose in fruit ; limb o-partite, 

 segments more or less equal, all developed more or less into petiolate 

 elliptical acuminate foliaceous, persistent lobes. Corolla tubular, some- 

 what funnel-shaped, submembranous, puberulous outside, shaggy 

 inside ; throat bearded ; limb 5-lobed ; lobes ovate-lanceolate, valvate 

 in aestivation. Stamens 5, inserted about the middle of the corolla-tube • 

 anthers linear-oblong, sessile. Disk hemispherical. Ovary 5- celled ; 

 style filiform, included, "with 2 linear little-dilated erect hirsute 

 branches" (Hook, f ) ; ovules very numerous, inserted on tumid 

 placentas. Fruit subglobose, subtruncate at the apex, 5-celled ; dis- 

 sepiments thin ; seeds numerous. — A monotypic genus with opposite 

 petiolate leaves, entire or cleft lanceolate interpetiolar stipules, and 

 rather small flowers clustered in dense axillary not involucrate cymes. 

 This genus as well as the previous one may perhaps be reducible to the Ceylon 

 genus Schizostigma, Am.

Calyx-tube oblong in flower, oval in fruit, more or less compressed ; 

 limb deeply and unequally 5-6-lobed, " glabrous or silky outside ; 

 throat pubescent ; lobes ovate, obtuse, valvate in aestivation. Anthers 5 

 sessile, inserted about the middle of the corolla-tube, linear, glabrous, 

 included. Disk shortly tubular, truncate. Ovary 3- or 5-celled ; style 

 slender, 3- or 5-cleft ; branches linear ; ovules numerous in each cell ; 

 dissepiments thin. Berry many-seeded. Seeds small, ancrular. — A 

 genus confined to this flora, consisting of somewhat cottony or hispid 

 or silky erect shrubs, with opposite petiolate leaves, entire inter- 

 petiolar stipules, and slender bracteolate flowers clustei-ed in subsessile 

 axillary solitary heads, which are enclosed in one or two campanulate 

 or connate involucral bracts.
