    General
    A many-stemmed perennial herb, or shrub(?)
    Stem
    Stems simple, somewhat thick, cylindric or c. 4-angular, densely hairy towards the apex, glabrescent and striate below Stems simple, somewhat thick, cylindric or c. 4-angular, densely hairy towards the apex, glabrescent and striate below.
    Leaves
    Leaves opposite, petiolate; lamina 6–15 × 3.8–12 cm, broadly ovate, attenuate and decurrent at the base into a winged petiole, acuminate acute at the apex, regularly dentate in the upper 1/2–2/3 with broad deep teeth up to 12 mm wide, or subentire, strongly discolorous, drying nearly black and sparsely hairy-scabrid with short hairs on the upper surface, ± densely whitish-green or brownish-yellow tomentose beneath; midrib rather thick Leaves opposite, petiolate; lamina 6–15 × 3.8–12 cm, broadly ovate, attenuate and decurrent at the base into a winged petiole, acuminate acute at the apex, regularly dentate in the upper 1/2–2/3 with broad deep teeth up to 12 mm wide, or subentire, strongly discolorous, drying nearly black and sparsely hairy-scabrid with short hairs on the upper surface, ± densely whitish-green or brownish-yellow tomentose beneath; midrib rather thick.
    Petiole
    Petiole up to 2 cm long, winged; the wings up to 5 mm wide, undulate, similar to the lamina in texture, colour and indumentum, each wing expanded at the base into a broad, rounded auricle Petiole up to 2 cm long, winged; the wings up to 5 mm wide, undulate, similar to the lamina in texture, colour and indumentum, each wing expanded at the base into a broad, rounded auricle.
    Inflorescences
    Inflorescence a terminal panicle up to 10 cm long, formed by opposite cymes; rhachis densely hairy; peduncles hairy, up to 5 cm long; pedicels up to 2.5 mm long; cymes few-flowered, the lowermost in the axils of the upper leaves, the rest subtended by foliaceous bracts, becoming progressively smaller towards the apex Inflorescence a terminal panicle up to 10 cm long, formed by opposite cymes; rhachis densely hairy; peduncles hairy, up to 5 cm long; pedicels up to 2.5 mm long; cymes few-flowered, the lowermost in the axils of the upper leaves, the rest subtended by foliaceous bracts, becoming progressively smaller towards the apex.
    Calyx
    Calyx 4–5 mm long, blackish on drying, appressed hairy mainly on the tube; lobes c. 1.75 mm long, triangular, acute or subacute, separated by wide sinuses, only slightly enlarged after anthesis Calyx 4–5 mm long, blackish on drying, appressed hairy mainly on the tube; lobes c. 1.75 mm long, triangular, acute or subacute, separated by wide sinuses, only slightly enlarged after anthesis.
    Corolla
    Corolla limb when in bud glabrous; corolla lobes not ciliate Corolla limb when in bud glabrous; corolla lobes not ciliate.
    Ecology
    In sparsely wooded grassland; 800–1400 m. Not known elsewhere.
    Note
    It approaches R. myricoides subsp. austromonticola (Verdc.) Verdc. in the shape of its leaves, but differs in having a denser indumentum on the leaf lower surface, broader undulate wings to the petiole, triangular and acute or subacute calyx lobes (oblong or oblong-semicircular and rounded at the apex in subsp. austromonticola ), and the corolla limb glabrous when in bud (pubescent in subsp. austromonticola ).  It is also somewhat similar to R. luembensis var. malawiensis (R. Fern.) R. Fern. with respect to the leaf shape and the strongly dentate leaf margin, but in var. malawiensis the leaves are smaller, not distinctly winged-petiolate and the calyx lobes are neither triangular nor acute.
    Distribution

    Anthers 1.25–1.5 mm long. Anthers 1.25–1.5 mm long
