Duration: Perennial Nativity: Native Lifeform: Forb/Herb General: Perennial herb arising from elongated tubers, erect to ascending, glabrous. Leaves: Thin and linear, incised and appearing compound, edges of divisions often rolled inwards, generally with 5 divisions, sometimes individual divisions reduced to small nubs, 5-15 mm long. Flowers: Purple, lavender, or reddish, funnelform, 3-4 cm long, outer sepals 3-6 mm long, with noticeable outgrowths, elliptic to oblong, stamens included, 18-20 mm, anthers 1-1.5 mm, ovary with 2 locules. Borne on peduncles 5-7 mm long. Fruits: Round capsules, 4-5 mm wide, with 1-4 black or brown ovoid seeds, to 3 mm. Ecology: Found in pine forests, oak woodlands, and plains, from 5,000-8,500 ft (1524-2438 m); flowering July-September. Notes: This lovely morning-glory is distinguished by its large, purple flowers and divided leaves. Leaves tend to be ascending up the stem. This species looks similar at first glance to Ipomea plummerae. However, I. plummerae has larger leaves and the flowers are borne on longer peduncles. Also note the presence of the outgrowths on the sepals, which are not present on I. plummerae. Ethnobotany: There is no specific use for this species, but the genus was used as an emetic, to treat worms and constipation, as a tonic, to treat asthma, and the tubers were used as food. Synonyms: Convolvulus capillaceus, Ipomoea muricata Editor: LCrumbacher, 2011
