226 NATURAL HISTORY OF PLANTS. 



II. ANCISTPOCLADEiE. 



11. Ancistrocladus Wall. — Flowers hermaphrodite; receptacle 

 concave. Sepals 5, subequal or unequal, imbricated. Petals 5, 

 inserted with perigynous sepals, contorted. Stamens 5, or more, 

 usually 10, of which 5 shorter are oppositipetalous ; 5 others alter- 

 nate perigynous ; anthers introrse, often finally versatile, muticous 

 or shortly apiculate ; cells sometimes unequal, longitudinally rimose. 

 Germen adnate at base to interior of receptacle (thence partly 

 inferior), otherwise free, 1-locular, apex conical or subhemispherical, 

 not hollow fleshy ; styles 3, tapering at base, apex thickened stigma- 

 tiferous ; ovule solitary, lateral or subbasilar, ascending, anatropous, 

 micropyle inferior. Fruit coriaceous, indehiscent, partly inferior and 

 adnate to receptacle, surrounded by much accrescent wing-shaped, 

 often subequal perigynous sepals. Seed ascending subglobose ; testa 

 intruded between folds of albumen ; albumen copious farinaceous 

 much ruminated ; embryo axile straight, radicle cylindrical inferior, 

 apex thickened and straight truncate ; cotyledons much wider than 

 long, divaricate truncate at apex. — Scandent glabrous shrubs ; twigs 

 often unciferous ; leaves alternate entire coriaceous, sometimes 

 sagittate, sessile or petiolate ; stipules small caducous, or ; flowers 

 in ramified cymiferous racemes or close to uncinate secund twigs, 

 caducous (Trojj. Asia, Oceania and Africa). See p. 214. 



III. LOPHIBE.E. 



12. Lophira Banks. — Flowers regular; receptacle subplane. 

 Sepals 5, afterwards unequal, imbricate. Petals 5, alternating with 

 sublrypogynous sepals and inserted with them, equal, contorted or 

 more rarely imbricated. Stamens oo, inserted with perianth, 

 oo -seriate; filaments erect, connate at base ; anthers linear muticous, 

 2-locular, introrse ; cells equal valved, longitudinally rimose. Germen 

 free long conical, 1-locular ; apex shortly 2 -fid ; lobes acute, apex 

 stigmatiferous subulate, reflexed, finally obliterate. Ovules cc 

 (oftener 8-1 G), sub-4-seriate inserted on central free placenta, 

 ascending, imbricate, antropous ; micropyle extrorse inferior. Nut 

 oblong, furnished with base of accrescent calyx ; sepals persistent
