Flowers ca. 4 cm long; pedi-cels solitary in the axils of the upper leaves, sparingly to moderately spreading short-pubescent, the hyaline trichomes 0.2-0.4 mm long; bracteoles 2, basal or submedial, filiform, usually 3-6 cm long; hypanthium obconic, spreading short-pubescent with trichomes 0.2-0.4 mm long; calyx lobes oblong, entire, ciliate, 4-5.5 mm long; corolla externally moderately to densely, spreading short-pubes-cent with trichomes 0.2-0.5 mm long, internally glabrous, the tube dark pink ex-cept for the distal 1.5-3 mm white border, 23-27 mm long, fenestrate, the basal 6-8 mm cylindric and 2-3 mm in diameter, expanding above to 5-7 mm in di-ameter, the lobes white, lanceolate or narrowly triangular, long-tapering, the 2 upper lobes 7-9 mm long, the 3 lower lobes slightly shorter; filament tube 30-32 mm long, glabrous, the filaments distinct and adnate to the corolla for about 1/3 their length, the anthers 3-4.5 mm long, the 2 shorter anthers ca. 3 mm long and apically white-tufted with a dense brush of white trichomes ca. 1 mm long, the 3 other anthers glabrous or sparingly pubescent externally.
