Duration: Perennial Nativity: Native Lifeform: Vine General: Perennial herb arising from elongated or globose tubers, erect to ascending or procumbent, not twining or only at the tips, glabrous. Leaves: Palmately divided leaves, rarely ovate or cone-shaped, 1-3 cm long. Flowers: Purple and broadly funnelform, to 3 cm long, sepals 7-9 mm long, stamens included, 8-10 mm, ovary 2 locular, ovoid. Borne on peduncles 1.5-2.5 cm long. Fruits: Globose capsules, 5-6 mm wide, the protruding stem to 5 mm long. Seeds finely tomentose, black to brown, 2-2.5 mm long. Ecology: Found on open, rocky slopes, from 4,500-8,500 ft (1372-2591 m); flowers August-September. Notes: This species is similar at first glance to Ipomoea capillacea, but I. plummerae has larger leaves 1-3 cm, compared to I. capillacea, which has leaves 0.5-1.5 cm. The flowers of I. plummerae are also borne on longer peduncles. Also, I. capillacea tends to have a neat appearence, with many of the leaves ascending up the stem, while I. plummerae tends to be less neatly arranged with the leaves in scattered clumps. Lastly, I. capillacea has noticeable outgrowths on the sepals. 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: Ipomoea muricata, several others, see Tropicos Editor: LCrumbacher, 2011
