Leaf blades 2–7 cm wide, lobe apex rounded to acute. Inflorescences: each flower loosely enclosed within 2 bracts; peduncle hispid, hairs retrorsely curved. Flowers: petals apically 2-fid, corolla 2–3 mm diam. Pepos 4–5 mm, loosely enclosed by persistent bracts.
Phenology: Flowering Aug–Oct(–Nov).
Habitat: North slopes, cliff bases, canyon bottoms, stream sides, riparian scrub, willow-ash, cottonwood-willow, hackberry-acacia, oak woodlands
Elevation: 1000–1700 m
Distribution
Ariz., N.Mex., Mexico (Chihuahua, Sonora).
Discussion
Sicyosperma gracile is recognized by its annual duration, minute salverform corollas with white, apically bifid petals, each flower enclosed within a pair of basally cordate bracts, and relatively small, 1-seeded, dry, indehiscent, unarmed pepos loosely enclosed by bracts. Specimens sometimes show only staminate inflorescences, but apparently this is an artifact of collection rather than an indication that the plant is unisexual.
