Under-shrub. Khizome obliquely erect, narrow, mainly rooting towards 

 the neck. Stems erect or ascending, slenderly terete, glabrous, smooth, or 

 more or less suhscabrous, or sometimes sparingly armed with patent and 

 nearly straight prickles, flexuous above, branched ; branches slender, 

 sometimes flexuous, terete, glabrous, smooth. Leaves alternate, erect- 

 patent, long-petioled, ovato-orbicular in outline, cordate at the base, 2^-11 

 cm. across, membranaceo-chartaceous, nearly glabrous beneath, pubescent 

 on the veins above, deeply and palmately 5-9-fld with narrow and obtuse 

 sinuses ; lobes again inciso-lobulate with narrow sinuses ; lobules irregularly 

 inciso-dentate with vary argute narrowly deltoid and often more or less 

 falcate ascending teeth ; the mid-lobe largest and outer lobes gradually 

 smaller ; main nerves palmately radiating from the base ; lateral veins as- 

 cending, one to each lobule ; veinlets finely anastomosing ; petiole slender, 

 strict, terete, slenderly canaliculate in front, dilated and glandular- margined 

 at the base, glabrous and sometimes armed with a few incurved spreading 

 prickles, lj-7cm. long; stipules adnate bt±low, subulate-lanceolate, sharply 

 pointed, thin, glabrous, entire and minutely glandular-margined, 3-11 mm. 

 long in the free portion, veins running upwards. Cyme terminal and often 

 in the axil of the uppermost leaf, loose ; peduncle filiform, with small bracts 

 which have taper-tipped and glandular-margined linear stipules ; pedicel filiform, 

 erect-patent except an erect central one, glabrous, 1 J-3J cm. long. Flower 

 about 13 mm. across. Calyx shallowly campanulate, 5-fid ; the tube 

 shortly and broadly obconical, thick, glabrous, but pubescent at the bottom 

 internally ; lobes erect-patent in flower, but enlarged in size and reflexed 

 together with the tube in fruit, deltoid-ovate, with a minute and narrow simple 

 or trifid acumen at obtuse or sometimes nearly emarginate apex, entire and 

 often loosely glandular-hairy on the margin, woolly-pubescent towards the 

 margin; veins obscure superficially. Petals 5, white, small, subrhombeo- 

 orbicular, round at the apex, clawless and broadly obtuse at the base, 

 entire, thin, with fine and flabeliate veins, 4|-5 mm. long, 4j-5j mm. broad. 

 Stamens numerous, inserted on the throat of the calyx-tube ; erect, unequal
