Somewhat taller than the last, more downy, covered with whitish, incurved hairs. Leaves, slightly broader, short-petioled or sessile. Flowers, small, in the upper axils. The tufts of hairs belonging to the seeds are very soft and silky. July to September.
In all the plants of this genus, the calyx-tube is much prolonged beyond the ovary, and must not be mistaken for the real flower-stalk. Bogs, Maine to Minnesota, south to Virginia.
