 pointed at the apex, cuneate or rounded at the base, sharply often 

 doubly serrate, with straight glandular teeth, and slightly divided 

 above the middle into 3 or 4 pairs of small acuminate lobes; about 

 one-third grown when the flowers open at the end of May and then 

 very thin, concave, yellow-green, roughened above by short white 

 hairs and slightly villose along the midribs and veins below; mature 

 leaves not seen; leaves on vigorous shoots ovate, rounded at the 

 broad base, more coarsely serrate, slightly lobed and often 6-7 cm. 

 long and 5-6 cm. wide, with thick midribs, slender primary veins, 

 and stout broadly winged slightly glandular petioles. Flourrs 2.5- 

 2.6 cm. in diameter, on short slender pedicels, in 5-12-flowered corymbs ; 

 calyx-tube narrowly obconic, the lobes gradually narrowed to the 

 base, long, slender, laciniately glandular-serrate above the middle,
