Leaves 15-40, rosulate or rarely closely imbricate on a short stem; petioles often 3-5 cm long, dilated, squamiform and 3-nerved below the basal articulation; leaflets 3, very shortly petiolulate, ovate-orbicular, somewhat truncate and broadly incised at the apex, conduplicate-falcate, glabrous above, pilose especially on the medial nerve beneath, impresso-punctate when dried, the medial 0.6-1.4 cm long, 0.5-1.1 cm broad, the lateral rather smaller, slightly oblique. Peduncles 1-fld., rather shorter than the leaves, with 2 small alternate bracts rather above the middle. Sepals more or less broadly lanceolate, 7 mm long, densely adpresso-pubescent, ecallose. Corolla 1.8-2.5 cm long, sparsely pubescent, rosy, with a funnel-shaped yellow tube. Filaments, the longer 5.5-9 mm long, sometimes sparsely glandular-pilose, edentate. Ovary pilose at the apex, the chambers 2-ovuled; styles densely glandular-pilose. Capsule subglobose. Seeds endospermous.
