Curly Dock
Family Polygonaceae (buckwheat)
Rumex crispus.

The long, narrow, wavy-edged leaves of dock are among the first edible wild greens to appear after the beginning of the fall rains.  When boiled, they taste like lemony spinach and are a good source of vitamins A and C.  The chocolate brown seed stalks produced in fall are attractive both in the marsh and in flower arrangements.
