Vines with large trichomes, annual, densely to scattered pubescent throughout. Leaves ovate to suborbicular, 5-15 cm long, entire or 3 (-5)-lobed, basally cordate, the lobes apically acute to acuminate, pubescent. Flowers in 1-5-flowered, often dense cymose clusters of mature and developing buds and flowers, sepals long-lanceolate, 15-25 mm long, with linear-lanceolate apices, densely long-hirsute; corolla blue, purple or almost scarlet, throat often white, 3-5 cm long, the limb 4-5 cm broad.
