45. Phyllononia W. — Eeceptacle obconical. Sepals and petals 5, 

 alternate, valvate, inserted in throat. Stamens 5, inserted with 

 alternate petals under edge of epigynous disk ; filaments free ; anthers 

 2-dymous, introrse. Germen adnate to receptacle, 1 -celled ; style 

 very short ; stigmatose lobes 2, recurved ; placentas 2, parietal, 

 co -ovulate. Berry small, crowned by cicatrix of perianth. Seeds co , 

 more often few ; testa coriaceous rugose ; embryo minute globose- 

 pyriform in base of fleshy albumen. — Glabrous trees or shrubs ; leaves 

 alternate petiolate exstipulate ovate-lanceolate acuminate, entire 

 or serrate ; flowers (minute) inserted in upper surface of leaves below 

 apex of midrib, shortly racemose-cymose {Mexico, New Granada).

46. Clioristylis Harv. — Flowers (nearly of Phyllonoma) poly- 

 gamous ; receptacle shortly obconical ; sepals 5, and petals as many, 

 alternate deltoid perigynous valvate. Stamens 5 alternipetalous ; fila- 

 ments perigynous free short ; anthers introrse 2-rimose. Germen half- 

 inferior ; cells 2, complete or incomplete, co -ovulate ; styles 2, 

 stigmatose at capitellate apex, at first erect- coalite, afterwards freed 

 recurved. Capsule half-superior, conical at apex, septicidally 

 dehiscent by styles. Seeds co ; embryo...? — A shrub (habit of 

 Celastrum or Mhamnus) ; leaves alternate ovate-oblong acute glandular- 

 serrate petiolate exstipulate ; flowers small in small branching supra- 

 axillary racemes {Southern Africa). See p. 355. 



47 ? Sticlioneuron Hook f. & Thoms. — Flowers hermaphrodite 

 or polygamous, minute ; receptacle concave obconical (in males very 

 short) ; perianth-leaves 4, or more rarely 5, inserted in margin of 

 receptacle ; prsefloration imbricate. Stamens 4, 5, subepigynously 

 inserted with perianth-leaves and opposite to them ; filaments free, 

 dilated at base, finally elongated ; anthers short sub-2-dymous, 

 oblique within at top of filament, introrse 2-rimose. Germen (in 

 male flower 0) included in concavity of receptacle, inferior, 1- celled ; 

 style very short ; lobes 2, obtuse stigmatose ; placentas 2, parietal, 

 alternating with lobes of style, co -ovulate. Fruit...? — A small 

 shrub (?) ; branching nodose at leaves (articulate ?) ; leaves alternate 

 shortly petiolate oblong-lanceolate acuminate entire membranous 

 glabrous, penni veined, 3-5-plicostate at base, transversely veined ;
