    Type
    Type: Sudan, Gonso (or Tertu), Cailliaud s.n. (MPU, holo.)
    Habit
    Large shrub or tree 4.5–12 m tall; bole often buttressed at the base.
    Bark
    Bark grey-purple, rough, flaking to leave pale patches; slash meat-red with paler streaks, watery, with white gum; ultimate branchlets yellowish brown tomentose to tomentellous, 3–7 mm wide, at length becoming ridged, rough, grey and exfoliating; bud-scales triangular, 2–2.5 mm long, 1.5–1.8 mm wide, tomentellous
    Leaves
    Leaf-blade ± orbicular in outline, 3–5lobed, 8.5–17 cm long, 8.5–17.5 cm wide, lobes subequal, wide, 4–7 cm long, 7–9 cm wide, apices acuminate, ± 3 cm long, 0.2 cm wide, base cordate, sinus 3–5 cm deep, edges overlapping, tomentellous above, densely yellow-brown tomentose with 6–8armed pale stellate hairs below.
    Petiole
    Petiole terete, 8–12 cm long, 2–3 mm wide, densely yellow-brown tomentellous; stipules caducous.
    Inflorescences
    Inflorescences borne 5–8 at the apex of leafless stems, 4–8.5 cm long, 2–4 cm wide, yellow-brown, tomentellous and densely stellate-hairy, with 3–10 lateral branches, lowest branch 3–9 mm from the base, 15–35 mm long, bearing 1–4 partial peduncles, each 1–3-flowered
    Flowers
    Flowers with perianth green outside, red inside, widely campanulate, 9.5–13 mm long, 11–16 mm wide, divided into 5 oblong acute lobes, 5–9 mm long, 3–4 mm wide, outside velutinous, densely covered with short yellow-brown (when dried) stellate hairs which completely obscure the epidermis, inside glabrous apart from the upper 2/3–3/4 of the lobes which more sparsely covered in patent white, simple hairs
    Fruits
    Fruit with follicles ± ellipsoid, 7–12 cm long, 2–3 cm wide, nearly dehiscing flat, then slightly shorter, 4.5–8 cm wide, rostrum long, stout, straight or curved, 1–3 cm long, stipe short and stout, 0.2–0.5 cm long, pericarp woody, 2–4 mm thick, outer surface brown, tomentellous, inner surface yellow, drying dull orange, softly tomentose except the placenta which is covered in urticating yellow hairs ± 2 mm long.
    Seeds
    Seeds with stout, peg-like stalks 2–3 mm long, persisting on old fruits; seeds ellipsoid, 11–12 mm long, 7–8 mm wide, greyblack, hilum sub-apical, round, 1 mm wide, at the margin of the aril; aril large, rounded, apical, 5 mm wide, 2 mm high, red, drying orange or red
    Figures
    Fig 2, p 15
    Ecology
    Wooded grassland; 750–1200 m
    Conservation
    This species is here assessed as “Least Concern” in view of its large geographic range and because of its common habitat.
    Note
    Sterculia setigera is closely related to Sterculia africana, the flowers being very similar apart from indumentum, the fruits being almost identical. It is distinguished from the latter by the 6–8-armed stellate hairs that make the lower leaf-blade tomentose and the perianth yellow-brown velvety, and are so dense as to entirely obscure the epidermis below. In addition, the leaves are at least twice the size usual in Sterculia africana. However, the latter is a variable species and some larger leaved specimens from T 3 with thicker indumentum than the norm have been treated, for example by Brenan (T.T.C.L.: 603 (1949)) as S. setigera. Throughout its range, S. setigera seems to be rather constant in leaf shape and size, and in perianth indumentum. A discordant element, with the indumentum of the lower leaf-blade silkily white, occurs in Ethiopia. This seems referable to S. cinerea A.Rich., normally treated as a synonym of S. setigera. Further investigation is warranted.
