Perennials, with entire to pinnatifid leaves, the blades decurrent on the petioles. Peduncles solitary, or in fascicles of 2-4 in the axils. Calyx campanulate, 5-lobed, in fruit somewhat enlarged, but not bladdery-inflated, close-fitting to the berry, thin, not angled nor ribbed, and faintly if at all veiny, open at the mouth, not exceeding the berry. Corolla rotate, white or cream-colored, often tinged with purple, the limb plicate. Stamens inserted near the base of the corolla; filaments long and slender; anthers oblong, opening by longitudinal slits; style and stigma as in Physalis. Seeds kidney-shaped, flattened, rugose-favose or punctate. [Ground-Sarac/io, the latter a genus named in honor of Isidore Saracha, a Spanish Benedictine botanist.]

An American genus, consisting of half a dozen species, natives of Mexico and the southwestern United States. Type species: Chamaesaracha Coronopus (Dunal) A. Gray.
