Schoenoplectiella K. Lye.
A genus of ca. 45 species, annual (rarely perennial) herbs, subcosmopolitan, but especially tropical/subtropical and Asian. As demonstrated by Lye (2003), Jung & Choi (2010), Muasya et al. (2009), Shiels & Monfils (2012), and Shiels et al. (2014), Schoenoplectiella is morphologically, genetically, and phylogenetically distinct from Schoenoplectus and warrants generic status. The circumscription corresponds to Schoenoplectus sections Supini and Actaeogeton.
