Some of the western material is similar, but not, I think the same species. E. manillata is characterized by the broad-beaked achene with rather prominent vertical cells, The material from western U.S. has more "convex" surface with less prominent markings. Jescot's Epalustris (Wisconsin) has narrow achenes with prominent cell structure of tubercle. Saturday (Feb. 22). Took train from Grand Central to Harlem. Walked around Crotton Point.

This species occurs as
