Main root rather heavy, branched; rootlets usually many, long and 
slender; stem herbaceous, glabrous, simple, erect, 6 — 80 inches high; 
tendrils rarely present near the summit; leaves ovate, thin, 5 — 9-nerved, 
more or less whitish pubescent beneath, 2 — 6 inches long, 1—4 inches 
wide, apex acute, acuminate, cuspidate, or obtuse, base cordate or 
rounded, margin entire or erose-denticulate; petioles 1 — 3 inches long;

Britton and Brown give the range of this species as from Virginia 
to Minnesota and Florida. The bowers appear in May and June. The 
habitat is along fence-ways and in thickets or open places. Iowa speci- 
mens at hand are from Winneshiek, Fayette, Johnson, Emmet and Lyon 
counties. The State University herbarium has specimens from the addi- 
tional counties of Henry, Winnebago, Calhoun, Delaware and Muscatine 
counties. Barnes, Reppert and Miller reported the species from Scott 
county and Peck from Hardin county.
