Ipomoea balioclada Urb. , Symb. Antill. 9 : 245. 1924. (Urban 1924b: 245) Type. CUBA. Prov. Oriente [ Guantanamo ], Sierra Maestra supra Daiquiri, c. 800 m, 28 Oct. 1916, E.L. Ekman 8080 (holotype S07-4401, isotypes BM, G, NY). Description. Twining perennial, stems somewhat woody, glabrous but covered in numerous flat black glands. Leaves petiolate, 5-9 x 3-6 cm, deltoid, acuminate, base truncate with rounded auricles, margin slightly sinuate, both surfaces glabrous; petioles 1.5-4 cm, glandular. Inflorescence of pedunculate axillary cymes; peduncles 2.5-5 cm, glandular, glabrous; bracteoles lanceolate, 2.5-3 mm long, caducous; secondary peduncles 6-10 mm; pedicels 16-18(-25) mm; sepals unequal, rather rigid, glabrous with prominent scarious margins, elliptic, obtuse to rounded, outer 6-9 x 4-6 mm, inner 10-12 x 6-7 mm; corolla 5-5.5 cm long, funnel-shaped, glabrous, pink, stamens shortly exserted. Capsules ovoid, 12 x 9 mm, rostrate, glabrous; seeds 5 x 3 mm, long-pilose on the margins with hairs up to 12 mm. Distribution. Endemic to eastern Cuba in the Sierra Maestra. We have not seen any collections other those by Ekman. CUBA. [ Guantanamo ?]: Sierra Maestra, Arroyo Jimenez , E.L. Ekman 14805 (HAC, S). Note. Although O'Donell annotated specimens of this species as Ipomoea alterniflora , it is very distinct because of the black glands on the stem, peduncles and, sometimes, the petioles. The corolla is pink.
