This northeastern taxon is close to verrucosa and tenuis, but can be distinguished by its more robust stems and several other characters; 2n = 38 or 39 (FNA 23). It was reported (as a variety) from Ky. in FNA 23, but details are not available. A coll. from the Murphy's Pond area in HICK (KY) has been annotated "var. ?pseudoptera" by S.G. Smith, and there are also records from adjacent w. Tenn. (Ch). Further research is needed to map this taxon better within the Ohio Valley.
