IdentificationThe leaves of Perfoliate Pennycress are not truly perfoliate; rather, they are sessile and clasp the stem with backward projections. In any event, this leaf condition plus the relatively heart-shaped pods will identify this plant. The flowers are white, in a rather dense, globular cluster at the top of the stem or a branch.
Taxonomic CommentsSynonyms include Thlaspi perfoliatum and Microthlaspi perfoliatum. See Weakley (2018) for the reasoning behind the name changes.
