CommentsThe leaves of Arrow Arum superficially resemble those of another wetland plant, Sagittaria latifolia (Common Arrowhead). While the leaves of Arrow Arum have pinnate venation (e.g., a central vein with lateral veins), the leaves of Common Arrowhead have palmate venation (even though many of these veins appear to be parallel). Common Arrowhead also produces a narrow raceme of showy white flowers with 3 petals, which has a very different appearance from the inflorescence of Arrow Arum. Another common name of Peltandra virginica is Tuckahoe.
