Discussion

The report of Ipomoea capillacea from Alabama (J. T. Kartesz and C. A. Meacham 1999) was probably based on a specimen of I. muricata.

(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).
