    General
    A tall shrub; branches leafy, somewhat flattened and ± pubescent towards the apex, subterete and glabrous in the lower part with a pale brown bark
    Leaves
    Leaves 9–15 × 6–8 cm, broadly ovate, rounded at the base with the lamina produced into a narrowly cuneate portion about the midrib base to become somewhat decurrent on the upper part of the petiole, acuminate at the apex, regularly crenate on the margins from near the base to the apex with crenations 4–11 mm wide and 1–1.5 mm high; lamina thickly membranous, appressed sparsely hairy and olivaceous on the upper face, hairy to nearly glabrous and greyish beneath; petiole c. 10 mm long, with the decurrent lamina forming undulate wings in its apical part, pubescent Leaves 9–15 × 6–8 cm, broadly ovate, rounded at the base with the lamina produced into a narrowly cuneate portion about the midrib base to become somewhat decurrent on the upper part of the petiole, acuminate at the apex, regularly crenate on the margins from near the base to the apex with crenations 4–11 mm wide and 1–1.5 mm high; lamina thickly membranous, appressed sparsely hairy and olivaceous on the upper face, hairy to nearly glabrous and greyish beneath; petiole c. 10 mm long, with the decurrent lamina forming undulate wings in its apical part, pubescent.
    Inflorescences
    Inflorescence a terminal panicle up to 8 cm long, with the rhachis and branches rather hairy; cymes loosely many-flowered; peduncles up to c. 4.5 cm long, pedicels 5–25 mm long, pubescent Inflorescence a terminal panicle up to 8 cm long, with the rhachis and branches rather hairy; cymes loosely many-flowered; peduncles up to c. 4.5 cm long, pedicels 5–25 mm long, pubescent.
    Ecology
    Afromontane evergreen rainforest; 1100–1200 m. Not known elsewhere.
    Note
    This taxon approaches R. sansibarensis subsp. sansibarensis in having large leaves and reflexed calyx lobes. It differs from it in leaf shape (broadly-ovate, not elliptic) with the decurrent base forming two undulate wings on the upper part of the petiole, and with the margin regularly crenate (not dentate-mucronate), and the lamina appressed hairy above (not glabrous), and hairy beneath (not completely glabrous or only sparsely hairy on the nervation); and in the hairy inflorescence (not glabrous) and the corolla lobes glabrous outside (not pubescent or puberulous as in subsp. sansibarensis).
    Distribution
    Zimbabwe District code: ZIM E.
    Habit
    A tall shrub; branches leafy, somewhat flattened and ± pubescent towards the apex, subterete and glabrous in the lower part with a pale brown bark.
    Calyx
    Calyx tube 4 mm long, campanulate; lobes c. 3.5 mm long and c. 3 mm wide, oblong, obtuse at the apex, reflexed, minutely lepidote on the inner face. Calyx tube 4 mm long, campanulate; lobes c. 3.5 mm long and c. 3 mm wide, oblong, obtuse at the apex, reflexed, minutely lepidote on the inner face
    Corolla
    Corolla tube 11 mm long; corolla lobes 12–14 mm long and 5–8 mm wide, obovate-oblong, obtuse, glabrous on the outside. Corolla tube 11 mm long; corolla lobes 12–14 mm long and 5–8 mm wide, obovate-oblong, obtuse, glabrous on the outside
    Stamens
    Stamen filaments exceeding the corolla tube by c. 3 cm; anthers c. 2 mm long. Stamen filaments exceeding the corolla tube by c. 3 cm; anthers c. 2 mm long.
