Key to Sagittaria

A genus of about 25 species, herbs, primarily of the Americas. Groups (and Complexes within the Graminea Group) shown in the key and text are based on Keener (2005).

Key advice:Portions of this key (and treatment) are provisional. The taxonomy and best characters to use in the linear-leaved species is particularly problematic.
