Schoenoplectiella mucronata inflorescence M. Simonis inflorescence

A Eurasian species, appearing in North America with increasing frequency in disturbed and early successional wetlands, and wetland restorations. First collected in Michigan by D. Gaebel in 2013 in a wetland created from a former pasture in Ingham Co. 

Said by some workers to be perennial, our plants clearly seem to be soft-based annuals. With its triangular stem, this might seem to resemble Schoenoplectus pungens. But in addition to the shorter anthers, the scales of Schoenoplectiella mucronata are obtuse to acute, with the midvein forming a short cusp ca. 0.1–0.2 mm long. In Schoenopectus pungens, the apex of the scales are bifid, with the midvein extending between the lobes as a firm excurrent tip ca. 0.5–1 mm or more long.
