Sagittaria platyphylla (Engelm.) J.G. Sm.[FNA22, HC2]
delta arrowhead
Publication: N. Amer. Sagittaria. 29. 1894.
Origin: Introduced from the southeastern U.S.
selected vouchers: WTU
Notes: FNA22: "Sagittaria platyphylla has been accepted at the variety level, i.e., Sagittaria graminea var. platyphylla (C. Bogin 1955; J. W. Wooten 1973; E. O. Beal et al. 1982). After studying dozens of populations in the field from much of its range and hundreds of herbarium specimens, we have concluded that this taxon should be recognized at the specific level instead, a conclusion supported by cladistic analyses of morphologic characters (R. M. Kortright 1998)"
