    Type: Tanzania, Morogoro District: Uluguru Mts, NW side, Schlieben 3415 (?B†, holo.; BR!, BM!, M, P!, all iso. labelled Schlieben 3415a)
    Shrub or small tree to 8 m high; stems sparsely branched, becoming thick and lenticellate; young stems and branches covered with dense small sessile stellate ± equal-rayed hairs ± 0.2 mm diameter, glabrescent, also with spreading soft bristles to 7 × 0.2–1 mm tapering to an acute point, usually simple, sometimes forked, purple becoming yellow to brown, densely tomentose with short glistening hairs
    Leaves alternate, dark green, membranaceous, ovate to broadly ovate, (16.5–)20–40 × 8–14 cm, bases cuneate sometimes decurrent and unequal, margins occasionally sinuate, apices acute to acuminate; lower surfaces of young leaves mealy and densely tomentose-stellate, hairs as on stems, becoming more confined to veins and midribs with maturity; upper surfaces glabrescent, both surfaces with prominent 7–11 alternate pairs of veins, bristles absent; petioles 3.5–9 cm long, bristles absent
    Inflorescences terminal to subterminal becoming lateral, multiply forked, manyflowered (usually 100+) umbellate cymes borne in pyramidal candelabra-like corymbs up to 12 cm broad apically; flowers 5-merous, erect or nodding; flowering axes densely stellate-tomentose, bristles absent; peduncles 0–6 mm long in flower and in fruit, becoming glabrous and woody; pedicels erect to recurved and 3–9 mm long in flower, erect and 6–9 cm long in fruit, glabrous, woody, thickened beneath calyx
    Calyx campanulate to cupulate, 1.8–2.5 mm long, stellate-tomentose in bud sometimes glabrescent with small brown glands externally, glabrescent internally, lobes triangular or ovate, 0.5–1.4 × 0.8–1.5 mm, obtuse, stellate-tomentose externally; adherent basally in fruit, later becoming reflexed, 1.5–2.5 × 1.5–2 mm, glabrous
    Corolla pale purple to violet, stellate, 12–18 mm diameter; tube 0.7–1 mm long, stellate-tomentose externally, glabrous internally; lobes strongly reflexed, lanceolate, 4–6.5 × 0.9–1.5 mm, acute, stellate-tomentose externally, often with small stalked glands internally
    Stamens equal; filaments free for ± 0.3 mm, glabrous; anthers bright yellow becoming brown, poricidal, 2.8–3.2 × 0.7–1.1 mm
    Ovary brownish, 0.5–0.8 × 0.3–0.6 mm, with scattered stellate hairs apically, ?bilocular; style straight, stout, 4.2–5.2 × 0.4–0.5 mm, stellate-pilose for lower half, glabrous above, exserted up to 1.5 mm; stigma capitate, slightly bifid, 0.4–0.5 mm diameter
    Berries smooth, yellow to orange-red, globose, glabrous, 6–10 mm diameter, often falling from pedicels when ripe, pericarp somewhat leathery. Seeds 4–16 per berry, light to dark brown, obovoid, orbicular, elliptic or reniform, 3–3.3 × 2.6–3 mm, flattened, minutely foveolate; sclerotic granules absent
    Fig 18/12 & 13, p 152
    Moist forest, often on riverine paths or river-banks; 1450–1850 m
    Though only represented by a few specimens, most authors working in this geographical area have recognised that S. schliebenii is a distinct species. It is closely related to S. schumannianum, from which it can be distinguished by its characteristic yellowish densely pubescent bristles (on which stellate hairs with a slightly longer median ray are sometimes discernible) which are confined to the stems and branches, by its large ovate eventually glabrescent dark green leaves with prominent venation, and by its smaller buds and seeds. From the material examined, including several isotype specimens, the inflorescences of S. schliebenii seem to be virtually epedunculate (with the peduncle either absent or < 6 mm long), and several long forked branches arising almost basally – these may have been what Werdermann erroneously noted as 4 cm long peduncles in his diagnosis. Werdermann’s protologue cited the holotype as Schlieben 3415 without any type locality. Schlieben’s first set was deposited in Berlin and was destroyed in 1943. There are a number of isotypes of this species – but with the collection number Schlieben 3415a. Lester in 2005 selected the BR specimen as the lectotype of this species and the BM specimen as the isolecto., but these were not published, and there are a number of extant isotypes.
