Duration: Perennial Nativity: Native Lifeform: Vine General: Perennial herb from a taproot; stems branching, prostrate or twining, to 2 m long; herbage densely pubescent. Leaves: Alternate along the stems, on petioles 2 mm to 5 cm long; blades variable, 1-7 cm long and 2 mm to 3 cm wide, ovate-elliptic to triangular-lanceolate or narrowly oblong, with projecting basal lobes, densely pubescent on both surfaces with loosely appressed hairs. Flowers: White to pink, usually solitary in leaf axils, on peduncles 0.5-10.5 cm long, sometimes in cymes of 2-3 flowers; sepals 5, oblong to ovate, 6-12 mm long, appressed-sericeous, with membranaceous margins; petals 5, fully fused into a bell-shaped corolla, 3 cm long, white to pink, at times with a reddish center, sericeous on the petal lobes. Fruits: Capsule globose, 7-8 mm wide, glabrous; containing 1-4 black seeds, 4 mm long. Ecology: Found on dry plains and hillslopes, and along the dry margins of ephemeral washes, from 2,500-6,500 ft (762-1981 m); flowers March-November. Distribution: c and s CA, AZ, s UT, s CO, NM, KS, OK, TX, NE; south to c MEX and in S. Amer. Notes: A twining vine with hairy stems and leaves, and pinkish, bell-shaped flowers which are twisted in bud; distinguished from the similar and introduced C. arvensis by its much narrower leaves; the longer calyx (6-12 mm compared to 3-5 mm long in C. arvensis); and being a perennial from a taproot (C. arvensis has creeping rhizomes). This species does not form the mats typical of the weedy C. arvensis. Ethnobotany: Unknown Etymology: Convolvulus means interwoven; equitans means overlapping in 2 ranks, probably referring to the arrangement of the leaves. Synonyms: Convolvulus hermannioides, C. simulans Editor: SBuckley 2010, FSCoburn 2015, AHazelton 2017
