Hey Tex, Those are the Erio's I found here in Mass. Dwarf sag leaves are broader, and not as brittle as Erios leaves. Eriocaulon leaves are stiff, pointy, short, and brittle. Very reminiscent of an air plant, or some sort of cactus. Sag. leaves are flat where as the Erio's have some thickness to them. Hope that helps.
Erio's kinda grow of each other, and you'll need separate them. (with the ones I have anyways)
