Passiflora lutea Linnaeus. Phen: May-Sep; Aug-Oct. Hab: Woodlands, forests, thickets, maritime forests. Dist: DE, PA, OH, IN, IL, MO, and e. KS, south to c. peninsular FL, s. AL, s. MS, s. LA, and s. TX.
Origin/Endemic status: Native
Taxonomy Comments: Sometimes divided into two varieties, the more eastern var. lutea (west to WV and AL) with pilose calyx, petioles, and stems, and more western var. glabriflora Fernald (east to WV and AL) with glabrous calyx, petioles, and stems; it is not clear that this is anything more than a minor polymorphism.
