Leaves ovate, acimiinate, rounded, cuneate or occasionally nearly 

 truncate at the entire often glandular base, finely doubly serrate above, 

 with slender glandular teeth, and divided into 4-6 pairs of narrow 

 acuminate spreading lateral lobes, nearly fully grown when the flowers 

 open about the middle of May and then very thin, light yellow-green 

 and hairy above, with short soft white hairs, and pale and glabrous 

 below, and at maturity membranaceous, glabrous, yellow-green, 

 smooth and lustrous on the upper and pale on the lower surface, 2.5-4
