    Flowers
    Flowers 2.5–3 cm long; pedicels up to 3 cm long, rufous-pubescent.
    Calyx
    Calyx lobes 4, 10–12 mm long, one c.8 mm wide, two c.5 mm wide, one c.2.5 mm wide, elliptic to obovate, rufous-pubescent outside, densely sericeous inside except on the overlapping margins.
    Corolla
    Petals 5, pink, c.5 mm wide and 15–16 mm long (25–30 mm according to Harms) including a claw 5 mm long, elliptic, the dorsal petal with a thickened and grooved claw, glabrous, the rest pubescent on the midrib inside.
    Stamens
    Stamens 7–10, c.25 mm long, the one opposite the dorsal petal free and almost glabrous, the rest fused and densely pubescent in the basal 5 mm; anthers dorsifixed.
    Pistil
    Ovary c.10-ovulate, c.7 × 3 mm, obovate, densely rufous-pubescent particularly on the margins, verrucose in the centre, stipe c.4 mm long, rufous-pubescent; style c.15 mm long, pubescent in the lower third; stigma capitate, bilobed.
