 straight gland-tipped teeth, and slightly divided into 2 or 3 pairs of 

 short broad acute lateral lobes, deeply tinged with red and covered 

 above with short white hairs and pale and glabrous below when they 

 unfold, nearly fully grown when the flowers open about the 20th of 

 May and then membranaceous, yellow-green and still slightly hairy 

 above especially along the midribs, and at maturity thick to subcori- 

 aceous, dark yellow-green and scabrate on the upper, pale on the lower 

 surface, 7.5-8 cm. long and 6-6.5 cm. wide, with stout yellow midribs 

 and 4 or 5 pairs of thin remote primary veins ; petioles stout, grooved 

 on the upper side, slightly wing-margined at the apex, 2.5-3 cm. 

 long; stipules foliaceous, lunate, glandular-serrate, soon deciduous; 

 leaves on vigorous shoots rounded or cordate at the wide base, more 

 coarsely serrate, often deeply divided into broad acute or acuminate 

 lateral lobes and often 6-7 cm. long and wide, with stout glandular 

 winged petioles 1.5-2 cm. long. Flowers about 1.8 cm. in diameter, on
