Flowers with the calyx 10 mm long, deeply lobed, the lobes sub-foliaceous, 8 mm long, lanceolate, tomentose outside and dispersed-pubescent inside with sessile, porrect, fer-rugineous stellae, the midpoints much shorter than the arms; corolla deep purple to purplish white, 3 cm across, lobed nearly to the base, the lobes unequal, lanceolate, tomentose outside; anthers 6-7 mm long, tapering, opening by rela-tively large terminal pores; ovary tomentose, the style pubescent, more so on the lower half, exceeding the anthers by 4 mm.
