Leaf blades broadly ovate or ovate, 15–30(–65) × 10–25(–48) mm, base shallowly cordate or truncate, apex usually acute, rarely obtuse. Inflorescences ± lax, 1–7-flowered, bracts linear. Flowers: sepals unequal, outers broadly ovate to suborbiculate, 5–9 mm, longer and wider than inners, base subcordate, apex acute, surfaces hairy; corolla white to pale blue or lavender, broadly funnelform, 20–25 mm, limb entire or 5-angled. Capsules broadly ovoid, 5–6 mm. Seeds 2–2.5 mm.

Distribution
Ariz., Mexico (Sinaloa, Sonora), Central America.
Discussion
Jacquemontia pringlei is endemic to the Sonoran Desert and reaches its northern limit of distribution in Pima County, Arizona; a report for Yuma County was evidently a mistake.
Selected References
None.
