 ribs and primary veins, 6-8 cm. long and 5-7 cm. wide; petioles stout, 

 broadly wing-margined nearly to the base, villose, 1-1.5 cm. in length; 

 leaves on vigorous shoots ovate, acuminate, abruptly concave-cuneate at 

 the base, more coarsely serrate and more deeply lobcd, often 8 to 9 cm.

peduncles from the axils of upper leaves ; calyx 



ymb;
