Corolla buds purple, yellow when open; tube 15.5-18 mm long, c. 1.8 times as long as lobes, c. 9.7 times as long as calyx, densely pubescent only beneath stamens and becoming less so further down in upper half, throat glabrous, glabrous outside; lobes 10-12 by 1.6-2.3 mm, 4.9-6.7 times as long as wide, linear to oblong, apex rounded to acute, ciliate or not, glabrous outside and inside. Stamens inserted at c. 15 mm from corolla base which is c. 0.8 of corolla tube length in the rehydrated flower, anthers 2.6-2.7 by 0.6 mm, 4.3-4.5 times as long as wide, apex 0.4-1.1 mm from corolla throat. Disk 1-1.1 mm long, c. 0.8 times as long as ovaries, glabrous, awl-shaped or deltoid, apex acuminate. Ovaries 0.8-0.9 mm high, glabrous; style 1.5-15 mm long (see note 1); style head 0.9-1.1 mm long.
