    Compositae, G. V. Pope. Flora Zambesiaca 6:1. 1992

    Habit
    A weak-stemmed perennial herb with a semi-woody rootstock.
    Stem
    Stems trailing or scrambling to c. 3 m. long, or erect and up to c. 1.2 m. tall, mostly solitary, branched above, very leafy throughout becoming leafless below, terete hollow, sometimes ± glandular-setose above otherwise glabrous.
    Leaves
    Leaves glabrous, largest and crowded on the upper stem, 5–20 x 0.25–1.6 cm., linear-elliptic becoming linear-lanceolate and sessile towards the stem apex, attenuate above, entire or less often ± recurved acicular-dentate to lobed on the margins, attenuate and shortly sagittate at the base in lower leaves, becoming amplexicaul and subauriculate-sagittate in upper leaves; lobes up to c. 2 cm. long narrowly runcinate-triangular; ± well developed leafy axillary shoots usually present, at least in upper leaves, the young axillary growth densely brown-lanate later glabrescent.
    Capitulum
    Capitula subsessile or shortly stalked, 2-many ± aggregated in terminal clusters or in lax corymbiform cymes; mature capitula subtended by 1-several subsessile buds; the bases of the capitula as well as the subtending buds and the capitula stalks enveloped in a white persistent lanate indumentum, synflorescence branches and capitula stalks densely glandular-setose or glabrous.
    Involucre
    Involucres c. 10–13 mm. long in fruiting capitula, cylindric later spreading, phyllaries eventually reflexed.
    Phyllaries
    Phyllaries few-seriate, imbricate, white-lanate outside where exposed, glabrescent towards the apices, usually also glandular-setose outside; the outermost c. 4 mm. long, narrowly ovate; the innermost 10–13 x 1.5–2.5 mm., lanceolate, ± obtuse at the apices.
    Florets
    Florets numerous.
    Corolla
    Corollas yellow, c. 10–13 mm. long, pubescent about the junction of the tube and ligule; ligule c. 3–4 mm. long, oblong.
    Fruits
    Achenes reddish-brown, 2.5–3 mm. long, narrowly ellipsoid, somewhat flattened, c. 4-angular with ribs on the angles, smaller ribs developing in between, the main ribs becoming thickened and transversely rugulose, glabrous; pappus white, dimorphic, c. 11 mm. long composed of minutely barbellate setae intermixed with down-like hairs.

    Compositae, H. Beentje, C. Jeffrey & D.J.N. Hind. Flora of Tropical East Africa. 2005

    Habit
    Perennial herb, usually weak-stemmed, from a stout rootstock, 0.4–1.5 m high; stems scrambling or straggly, to 9 m long; stems often reddish, hollow, glabrous or distally glandular-setose.
    Leaves
    Leaves shiny above, glaucous beneath, sessile, linear-elliptic to lanceolate, 4–20 cm long, 0.2–1.6 cm wide, base attenuate and shortly sagittate in proximal leaves, in distal leaves semi-amplexicaul and sub-auriculate, margins entire or less often with recurved teeth or spinules, sometimes lobed with the lobes narrowly triangular and to 2 cm long, apex attenuate, glabrous.
    Capitulum
    Capitula solitary or in few-headed rather dense Groups, these in turn in lax leafy corymbs or panicles; stalks of individual capitula short, white-tomentose and sometimes with stalked glands extending further down the inflorescence; involucre cylindric to campanulate, eventually with reflexed phyllaries, 10–15(–18,K3) mm long; phyllaries green with reddish or purplish tinge or tips, narrowly ovate to lanceolate, 2.5–13 mm long, obtuse, white-tomentose proximally, becoming more glabrous distally and on the inner phyllaries, distally ciliate, sometimes the outer and distal part of the inner glandular-setose.
    Florets
    Florets many per capitulum; corolla yellow, tube cylindric, 6–10 mm long, distally pilose; ligules 3–6.5 mm long, 0.5–1.2 mm wide.
    Fruits
    Achenes pale or reddish brown, narrowly ellipsoid, slightly flattened, 2.5–3.5 mm long, ribbed, rugulose but glabrous; pappus white, 7–11 mm long.
    Habitat
    Grassland, forest glades, road- and pathsides, bamboo zone; (900–)1500–3150 m
