Dig deeper at SERNEC, a consortium of southeastern herbaria.

This is one of a few arrowheads that has quite large and sagittate (arrowhead-shaped) leaf blades. The leaf shape is a bit more deeply cut at the base than is the common S. latifolia, but this can be variable. This species has a 5-angled leaf stalk, unlike others in the genus. Some of the most important characters in separating arrowheads lie in the seed (achene) shape; see references for these details. Read more at Vascular Plants of North Carolina.
