Duration: Perennial Nativity: Native Lifeform: Vine General: Herbaceous perennials, stems twining, herbage pubescent to hirsute with long, silky, appressed hairs, plants arising from a large, oblong, tuberous-thickened root. Leaves: Alternate, ovate to 3-5 times palmately lobed, the lobes elliptic to ovate, entire blade 2-8 cm long and 2-9 cm wide, margins entire to sinuate, acute to obtuse and mucronate at the tips, cordate at the base, blade surfaces pubescent to hirsute with long, silky, appressed hairs, borne on petioles 2-5 cm long. Flowers: Blue to violet, corollas funnelform, 5.5-8 cm long, 6-7 cm in diameter, sepals unequal, ovate and acuminate at the tips, more or less silky hairy, outer sepals 9-21 mm long, 5-11 mm wide, basally truncate, middle sepals asymmetrical, 9-19 mm long, 3-8 mm wide, inner sepals ovate-lanceolate, 9-20 mm long, 2-4 mm wide, bracts tapering to a point, acuminate, 5-12 mm long, stamens 30-35 mm long, with a few glandular hairs at the base of the filaments, the anthers arrowhead-shaped (sagittate), 3-4 mm long, stigmas 3-capitate, flowers borne solitary or in pairs on peduncles 15-18 mm long. Fruits: Globose capsules, 10-12 mm wide, surrounded by the sepals. Seeds ovoid, 5-6 mm long, brown to black, velvety and densely pubescent, 3-6 per capsule. Ecology: Found on rocky or sandy soils in rocky areas, stream beds, mesas, plains, and in oak woodlands, from 3,500-4,500 ft (1067-1372 m); flowering August-September. Distribution: s AZ, s NM, sw TX; south to s MEX and in S. Amer.. Notes: Distinguished from other regional Ipomoea by being perennial and very hairy with silky, white, appressed hairs on leaves and stems; deeply-divided palmate leaves; long sepals which are broad and gradually narrow to a point and have shorter spreading hairs; and especially the super-large purple flowers with white throats. This species also arises from a large storage tuber. Ethnobotany: There is no use recorded for this species, but other species in this genus have uses.
