the entire base, finely doubly serrate above, with straight or incurved 

 glandular teeth, and slightly divided into 3 or 4 pairs of slender acuminate 

 lateral lobes; more than half-grown when the flowers open from the 10th 

 to the middle of May and then dark blue-green and setose above and 

 sparingly villose below along the midribs and vcins^ and at maturity thin 

 but firm in texture, blue-green and scabratc on the upper surface, scabrate, 

 and slightly villose on the midribs and veins on the lower surface, 5-6 cm. 

 long and 3.5-4.5 cm. wide; petioles slender, narrowly wing-margined to 

 the middle, densely villose early in the season, becoming pubescent or 

 nearly glabrous, glandular, with persistent glands, 2-3 cm. in length; leaves 

 on vigorous shoots broadly ovate, short-pointed at the apex, rounded or 

 subcordatc at the base, more coarsely serrate and often 5-6 cm. long and

 pedicels, in small compact mostly 3-;')-flowered hairy corymbs, with con- 

 spicuous oblong-obovate coarsely glandular-serrate bracts and bractlets
