grown on slender pedicels ^'-1' long, in erect or nodding glabrous racemes 3'-4' long; 

 calyx campanulate, with lanceolate acute lobes, villous on the inner surface ; petals

Distribution. Upland woods in rich soil; Newfoundland, through the maritime 

 provinces of Canada, and westward along the shores of the Great Lakes, ranging 

 southward to northern Florida and westward to Minnesota, eastern Nebraska, east- 

 ern Kansas, and southern Arkansas. A form with acuminate leaves cordate or rarely 

 rounded at the base and pale-tomentulose below even at maturity (var. tomentula, 

 Sarg., nov. var.) is referred provisionally to this species. Vermont (Ferrisburg, C. E. 

 Faxon, June, 1881) to Ontario, and to Delaware, central Georgia, Missouri, and
