Duration: Annual Nativity: Native Lifeform: Vine General: Annual herb, 10-120 cm or more long, from a slender taproot; stems slender, erect when young and later trailing and slightly twining, with several low longitudinal ridges; herbage mostly glabrorus. Leaves: Alternate along the stems, sessile or nearly so; blades deeply incised into 5-9 linear to oblanceolate segments (the outer of which may be further divided), the segments 7-35 mm long and 1-3 mm wide. Flowers: Small but showy and pinkish, solitary (occasionally in pairs) in leaf axils on flower stalks 2-5 cm long; sepals 5, somewhat unequal, 3-6 mm long, oblong to lanceolate, with membranous margins; corolla funnel-shaped, 8-12 mm long, pink to lavender to white. Fruits: Capsules globose, 4-6 mm wide, tan-colored, on erect stalks; containing 1 to several seeds. Ecology: Found in rocky areas in chaparral, oak woodlands, and ponderosa pine forests; 3,000-7,000 ft (914-2134 m); flowers July-October. Distribution: AZ, NM, TX; south to s MEX. Notes: Distinguished from other regional Ipomoea by being hairless on leaves and stems; a growth form more low-growing and less robust than some of the larger morning glories; leaves deeply palmately dissected into thin, narrow divisions; a long peduncle (flower stalk); hairless sepals, and small pink corolla tubes that are about 1 cm long. Ethnobotany: Unknown Etymology: Ipomoea comes from Greek ips, a worm and homoios, like, referring to plant's vining growth form; costellata comes from costa, Latin for ribbed, referring to the stems.
