    Type
    Type from Katanga (Shaba) Province of Dem. Rep. Congo.
    Habit
    Perennial herb drying fuscous to reddish-brown, with a woody caudex up to c. 15 mm in diameter crowned with many short closely scaly shoots that elongate into stems c. 200–300 mm long, 1.25–1.8 mm diameter at base, erect, spreading, or prostrate, shallowly ribbed by decurrent scales, fastigiately branched, branches irregularly cymose, ascending at angle of 45°, mostly c. 50–120 mm long Perennial herb drying fuscous to reddish-brown, with a woody caudex up to c. 15 mm in diameter crowned with many short closely scaly shoots that elongate into stems c. 200–300 mm long, 1.25–1.8 mm diameter at base, erect, spreading, or prostrate, shallowly ribbed by decurrent scales, fastigiately branched, branches irregularly cymose, ascending at angle of 45°, mostly c. 50–120 mm long.
    Leaves
    Leaves all reduced to scales, those at extreme base of stem 1–2 mm long, those subtending branches 2–3 × 1–1.6 mm, lanceolate, cuspidate, thick-textured, margins minutely erose-ciliolate Leaves all reduced to scales, those at extreme base of stem 1–2 mm long, those subtending branches 2–3 × 1–1.6 mm, lanceolate, cuspidate, thick-textured, margins minutely erose-ciliolate.
    Flowers
    Flowers initially solitary at tips of nude peduncles mostly 10–35 mm long (measured from axil of bract to first flower), soon overtopped by usually 2, rarely 3, nude or rarely scaly peduncles, arising immediately or shortly below flower, terminating in a flower, the bracteate peduncles with buds in the axils of the bracts, the branching repeated to produce a lax 9–15-flowered irregular cyme Flowers initially solitary at tips of nude peduncles mostly 10–35 mm long (measured from axil of bract to first flower), soon overtopped by usually 2, rarely 3, nude or rarely scaly peduncles, arising immediately or shortly below flower, terminating in a flower, the bracteate peduncles with buds in the axils of the bracts, the branching repeated to produce a lax 9–15-flowered irregular cyme.
    Bracts
    Bracts c. 5 forming an involucre below the flower, c. 1–1.1 × 0.6–0.7 mm, lanceolate to ovate-lanceolate, cuspidate, margins very minutely erose Bracts c. 5 forming an involucre below the flower, c. 1–1.1 × 0.6–0.7 mm, lanceolate to ovate-lanceolate, cuspidate, margins very minutely erose.
    Pedicel
    Pedicels wanting Pedicels wanting.
    Perianth
    Perianth colour unknown; tube 0.5–1 mm long, external glands obscure; lobes 1.1–1.5 × 0.4–0.7 mm, oblong-lanceolate, obtuse, hood c. 0.3 mm long, margins inflexed, erose Perianth colour unknown; tube 0.5–1 mm long, external glands obscure; lobes 1.1–1.5 × 0.4–0.7 mm, oblong-lanceolate, obtuse, hood c. 0.3 mm long, margins inflexed, erose.
    Stamens
    Stamens inserted at base of perianth lobes; filaments 0.3–0.5 mm long, almost hidden by anthers; anthers 0.4–0.8 mm long Stamens inserted at base of perianth lobes; filaments 0.3–0.5 mm long, almost hidden by anthers; anthers 0.4–0.8 mm long.
    Style
    Style 1–1.8 mm long; stigma reaching nearly to top of perianth lobes
    Ecology
    Woodland; c. 1200 m.
    Note
    Thesium bequaertii may be no more than a form of T. unyikense from which it differs chiefly in its laxer, longer branches producing more flowers. There are three records of the plant in Zambia, from Mufulira, Ndola Hill and the nearby Baluba R.; Fanshawe 11023, cited under T. unyikense, was collected at Kitwe and seems more or less intermediate between T. bequaertii and T. unyikense.
    Distribution
    Also in Dem. Rep. Congo. ZAM W Zambia
    Pistil
    Style 1–1.8 mm long; stigma reaching nearly to top of perianth lobes.
    Fruits
    Fruit 2.5 × 2–2.3 mm, palest brown, strongly ribbed and reticulate. Fruit 2.5 × 2–2.3 mm, palest brown, strongly ribbed and reticulate.
