Discussion | Reports of Ipomoea nil from California are based on misidentified material of I. hederacea. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Ipomoea coccinea differs from I. hederifolia by reflexed pedicels (erect in I. hederifolia) and larger inner sepals (4.5–5.7 mm) than I. hederifolia (to 3–4 mm). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
