Stems	trailing or twining, ± warty or smooth.	usually trailing, rarely decumbent.
Leaf	blades usually orbiculate to ovate, sometimes cordate or 3–5-lobed, 70–180 × 70–160 mm, base cordate, surfaces glabrous.	blades lance-oblong, lanceolate, or linear, 100–120(–210) × 20–40 mm, base rounded, surfaces glabrous.

Flowers	nocturnal; sepals oblong to ovate, 6–8 mm, chartaceous to coriaceous, apex acute, outers each with ± corniform appendage 4–6 mm; corolla white, turning lavender in morning, salverform, limb sometimes ± campanulate, 30–75 mm.	sepals oblong or ovate, 12–20 mm, outers 12–14(–17) × 6–7 mm, inners 15–20 × 7–8 mm, coriaceous, surfaces glabrous; corolla ± white, throat purple inside, funnelform, 70–100 mm, limb 70–80 mm diam.

Phenology	Flowering Nov.	Flowering Apr–Sep.
Habitat	Disturbed sites.	Desert grasslands, oak woodlands.

Discussion	Ipomoea muricata has been spread as a contaminant in soybean seeds (C. R. Gunn 1970). The name Ipomoea turbinata Lagasca is illegitimate and has been misapplied to plants of I. muricata (G. W. Staples et al. 2006).
