FNA: Ipomoea pes-caprae vs. Ipomoea hederacea

	Ipomoea pes-caprae	Ipomoea hederacea
	bayhops, beach morning glory, goat's foot	ivy morning-glory, ivy-leaf morning-glory
Habit		Annuals.
Stems		twining.
Leaf		blades ± orbiculate, ovate, or 3–5-lobed, not palmatisect, 50–120 × 50–120 mm, base cordate, basal lobes ± pointed, surfaces hairy.
Peduncles		hairy, hairs retrorse.
Flowers		sepals ± lanceolate, 12–24 mm, herbaceous, proximally ovate, abruptly narrowed to ± curved or spreading distal portion notably longer than dilated base, abaxial surface, at least proximal 1/3, hirsute to hispid; corolla light blue, tube white or pale yellow inside, funnelform, 20–37(–45) mm, limb 17–35 mm diam. 2n = 30.

Phenology		Flowering May–Nov.
Habitat		Abandoned plantings, disturbed sites, gravel bars, roadsides.
