Hemicarpha micrantha of Michigan Flora.

Locally common on sandy-mucky shores of receding lakes, but easily overlooked because of its small size; its rather curly culms are quite inconspicuous when growing in a dense stand of Fimbristylis autumnalis, Schoenoplectus spp. and other associates. In Michigan, Lipocarpha is usually found in the same habitats as our Coastal Plain disjuncts, although it is actually of much wider distribution. A similar species, L. drummondii (Nees) G. C. Tucker, is known from adjacent Lucas Co., Ohio, and also the Indiana Dunes, and could be found in Michigan. It differs in having an inner scale (wrapping the achene) present and ca. 0.5–0.8 mm long. This scale is vestigial or absent in L. micrantha.
