    General
    A weak-stemmed shrub up to 3 m tall, or a slender tree 3–4 m tall, sometimes an under-shrub 0.65–1 m tall, profusely branched
    Branches
    Branches slender, 4-angled or the old ones terete, smooth or striate, lenticellate, usually not swollen at the nodes, subglabrous or sparsely to ± densely hairy, brownish to deep brown, usually persistently leafy, sometimes with axillary fascicles of leaves Branches slender, 4-angled or the old ones terete, smooth or striate, lenticellate, usually not swollen at the nodes, subglabrous or sparsely to ± densely hairy, brownish to deep brown, usually persistently leafy, sometimes with axillary fascicles of leaves.
    Leaves
    Leaves opposite or subopposite; lamina 5–13.8 × 2–5 cm (smaller in the leaves subtending the lower cymes and in those of the axillary fascicles, sometimes not more than 1.3 × 0.7 cm), usually rhombic or sometimes lanceolate or subobovate-oblong, attenuate or cuneate at the base and decurrent into the petiole, acuminate at the apex, deeply dentate on the margins with broad subapiculate teeth, the cuneate base entire, or some leaves completely entire, membranous, concolorous or somewhat discolorous, deep green above, paler beneath, often very sparsely appressed shortly pubescent on both surfaces, the hairs a little longer on the nerves beneath; midrib and lateral nerves rather slender; petiole up to 1.2 cm long, slender Leaves opposite or subopposite; lamina 5–13.8 × 2–5 cm (smaller in the leaves subtending the lower cymes and in those of the axillary fascicles, sometimes not more than 1.3 × 0.7 cm), usually rhombic or sometimes lanceolate or subobovate-oblong, attenuate or cuneate at the base and decurrent into the petiole, acuminate at the apex, deeply dentate on the margins with broad subapiculate teeth, the cuneate base entire, or some leaves completely entire, membranous, concolorous or somewhat discolorous, deep green above, paler beneath, often very sparsely appressed shortly pubescent on both surfaces, the hairs a little longer on the nerves beneath; midrib and lateral nerves rather slender; petiole up to 1.2 cm long, slender.
    Inflorescences
    Cymes 1–few-flowered, arranged in loose terminal panicles up to 9 cm long, the panicle not usually distinct, the uppermost pair of normal leaves sometimes subtending the 2 basal cymes; peduncles 4–5 cm long, not densely appressed or spreading hairy Cymes 1–few-flowered, arranged in loose terminal panicles up to 9 cm long, the panicle not usually distinct, the uppermost pair of normal leaves sometimes subtending the 2 basal cymes; peduncles 4–5 cm long, not densely appressed or spreading hairy.
    Calyx
    Calyx 5–7 mm long, campanulate, usually sparsely appressed hairy, rose-purple; lobes 2–3 mm long, oblong or oblong-semicircular, at least some lobes reflexed or spreading, pale pink Calyx 5–7 mm long, campanulate, usually sparsely appressed hairy, rose-purple; lobes 2–3 mm long, oblong or oblong-semicircular, at least some lobes reflexed or spreading, pale pink.
    Ecology
    "In riverine forest, dense mixed woodland, understorey thicket and the shrub layer of dry deciduous Kalahari Sand forest not subject to heavy fires (""mutemwa""); 960–1220 m."
    Note
      Pole Evans 2598 (PRE) from Botswana (between Tutume and Sebina?), with leaves smaller than usual for this species, probably belongs to R. reflexa . The specimens from Mozambique: MS., Barbosa 1018 (LISC) and 1582 (LISC; Z) and Garcia 323 (LISC), referred to Clerodendrum reflexum by Moldenke (in Phytologia 87 : 261, 1986), are a form of R. myricoides var. discolor with a very dense indumentum and large leaves (see note: R. Fernandes in Mem. Soc. Brot. 30 : 76 (1998). Rotheca reflexa usually approaches R. myricoides var. myricoides more closely than it does R. myricoides var. discolor (in indumentum and leaf shape).  However, some specimens, mainly from Zimbabwe, with leaf bases ± attenuate, leaf margins ± deeply and acutely dentate, and calyces (4)5.5–6 mm long, approach R. myricoides var. discolor in their denser indumentum on the leaves and calyces and in their distinct, more floriferous panicle.  See also the notes under C. myricoides var. discolor forma reflexilobatum in Mem. Soc. Brot. 30 : 75 (1998).

    Habit
    A weak-stemmed shrub up to 3 m tall, or a slender tree 3–4 m tall, sometimes an under-shrub 0.65–1 m tall, profusely branched.
