Najas flexilis (Willd.) Rostk. & W.L.E. Schmidt[FNA22, HC, HC2]
or slender naias, slender nymph, wavy water nymph

Publication: Flora Sedinensis. 382. 1824.

Origin: Native

selected vouchers: WTU

Notes: Abrams uses the Greek spelling Naias L.; here, like FNA and all recent authors, we use Najas L.

FNA22: "In habit, Najas flexilis is most similar to N. guadalupensis. When seeds are present, N. flexilis can be separated easily from the latter species by the glossy, smooth, yellowish seeds that are widest above the middle. In the northern United States and in Canada, N. flexilis is by far the most common species of Najas, although in the Ohio and surrounding areas, it is disappearing as eutrophication (depletion of oxygen from lakes) continues (W. A. Wentz and R. L. Stuckey 1971)."
