Range: Newfoundland to Ontario, southward to Pennsylvania, 
Ohio, and Kansas.

A very large species, with a stout and very deep taproot. Stem 
sometimes attaining to eight or ten feet in height but usually 
two to six feet tall, stout, erect, grooved, 
and smooth, simple or sparingly branched. 
The large basal leaves are sometimes 
more than two feet in length, oblong 
lance-shaped, broadening above the base, 
smooth but with thick ribs and veins 
and long petioles; stem leaves long- 
pointed and much smaller. Panicle very 
large and dense, sometimes nearly two 
feet in length, its branches nearly 
erect, often with leafy bracts among 
the whorled flowers. These are small 
and green with six sepals, six stamens 
and three styles, the calyx differing 
from that of the following species in 
that only one of the three enlarged, 
heart-shaped, veiny inner sepals or 
valves has a small tubercle on its back, 
or sometimes merely a thickening of 
the base of its midrib. Pedicels slen- 
der with a swollen joint near the base. 
Fruit an achene, sharply three-angled, 
about one-eighth of an inch long, smooth, 
shining, light brown. (Fig. 52.)
