Ipomoea geophilifolia K. Afzelius , Svensk Bot. Tidskr. 60 : 484. 1966. (Afzelius 1966: 484) Type. BRAZIL. Distrito Federal, Cabeca do Veado , March 1961 , E.P. Heringer 8029 (whereabouts unknown, possibly number cited erroneously, neotype E.P. Heringer 8030 (UB), designated here). Description. Relatively slender twining or trailing herb, stems pubescent. Leaves petiolate, 2 -5.5 x 2-5 cm, ovate to suborbicular, mucronate, cordate with narrow basal sinus, pubescent to subtomentose on both surfaces, paler beneath; petioles 1.5-3.5 cm, pubescent. Flowers in 1-3-flowered axillary cymes; peduncles 2-3 cm; bracteoles linear, 6-10 mm, pilose, persistent; pedicels c. 5 mm, densely pubescent; sepals subequal, 12-16 x 4-6 mm, densely pubescent, lanceolate, acuminate, inner paler and less hairy on paler margins; corolla 5-6.5 cm long, pilose, pink, funnel-shaped, the tube purple within, limb 4 cm diam., slightly lobed. Capsules and seeds not seen. Distribution. A local endemic species of cerrado in the Brazilian planalto at around 1100-1200 m near Brasilia. BRAZIL. Dist. Fed. : H. Irwin et al . 12261 (FTG, NY, MO); Campo Experimental UB, G. Kirkbride 1444 (F, K); E.P. Heringer 15396 (FTG). Goias : Mun. Cristalina, G. Hatschbach & J. Cordeiro 51799 (MBM); H.S. Irwin et al. 13773 (FTG). Typification. Afzelius cited Heringer 8029 as the type but as this is neither at S nor UB, it is possible the number was cited erroneously. Heringer 8030 was cited as a paratype and is at UB, so is here designated as neotype. Note. This species is distinguished by its relatively slender habit, suborbicular leaves, persistent bracteoles and lanceolate sepals 12-16 mm long.
