Inflorescences terminal or arising from apical leaf axil, simple or branched, subcapitate with ca. 2 flower pairs to shortly spicate, 4-5 cm; peduncle 1-5 cm, glabrous or pubescent; bracts ovate to oblong, 0.8-1.5 × 0.7-1.3 cm, caducous, green when young but soon scarious, often becoming gland-tipped pilose, apex acute; bracteoles ca. 2 × 1 mm, caducous so often appearing absent. Calyx 1-1.8 cm, gland-tipped pilose, 5-lobed almost to base; lobes narrowly lanceolate with one slightly longer than others, apex acuminate. Corolla blue or white, 3.5-5 cm, ventricose, outside gland-tipped pubescent but sometimes only on lobes, inside glabrous except for trichomes retaining style; tube basally cylindric and ca. 2.5 mm wide for 1-1.5 cm then bent and widened to ca. 1 cm at mouth; lobes oblong, ca. 6 × 5 mm, apex obtuse. Stamens 4, included; filaments sparsely hirsute, shorter pair ca. 4 mm, longer pair ca. 7 mm; anther thecae oblong-ovoid, ca. 2 × 1.2 mm. Ovary comose; style 2.8-3.2 cm.
