    Type
    Type: Tanzania, Morogoro District: Turiani, Paulo 182 (K!, holo., NHT, iso.)
    Habit
    Evergreen shrub or small tree 3–10 m tall.
    Branches
    Branches dark greyish brown, young stems with scattered, appressed greyish black stellate hairs; bud-scales caducous, filiform, ± 5 mm long, 0.5 mm wide, tomentose, brown
    Leaves
    Leaf-blade obovate to elliptic, 5.5–28 cm long, 2.5–15.5 cm wide, acumen ± 1 cm long, base cuneate, ± 5 pairs of main veins, glabrous above and beneath; petiole terete, ± 13 cm long, 0.15–0.3 cm thick, swollen, black and kneed at base and apex, indumentum as stem
    Inflorescences
    Inflorescence cauliflorous, in old leaf axils of branches 2–3 cm wide, ± sessile, clustered in large numbers, forming woody burrs 3 cm wide, 1 cm long; bracts 3–5, bilobed, distichous, increasing in size from the base up, up to 2.5 mm long, 1.5 mm wide; pedicels (6–)10–20(–28) mm long, 1 mm wide, articulated 2–4 mm from the base, indumentum greyish brown, stellate
    Flowers
    Flowers deep pink to dark red, drying blackish purple, ± 14 mm across, perianth divided to within 1–2 mm of the base into 4–6 patent lobes, lobes ovate-triangular, 5.5–7 mm long, 4 mm wide, margins involute, membranous, running full length of lobe, undulate, white, ± 1.2 mm wide, the outer surface of the lobes thinly covered with 4–16-armed stellate hairs, the largest hairs partly scale-like (rarely glabrous); inner surface thickly covered in papillae sometimes with occasional or thinly scattered red stellate hairs Male flowers with androphore cylindrical, 2–3 mm long, 0.8 mm across, glabrous or with scattered stellate hairs; anthers uniseriate, 8–10, glabrous. Female flowers as the male, but androphore absent, non-functional anthers forming a ring at the base of the ovary; ovary (3–)5-lobed, very densely grey, stellately tomentose, ± ovoid, 2–2.5 mm long, 1.5–2 mm wide; stigmas ± sessile, reflexed, ± 1 mm across, black
    Male
    Male flowers with androphore cylindrical, 2–3 mm long, 0.8 mm across, glabrous or with scattered stellate hairs; anthers uniseriate, 8–10, glabrous.
    Female
    Female flowers as the male, but androphore absent, non-functional anthers forming a ring at the base of the ovary; ovary (3–)5-lobed, very densely grey, stellately tomentose, ± ovoid, 2–2.5 mm long, 1.5–2 mm wide; stigmas ± sessile, reflexed, ± 1 mm across, black
    Fruits
    Fruit borne ± 1 m from the ground on a woody, hooked pedicel 1.5–2 cm long, 0.3 cm thick, follicles 5, patent, green or yellow marked red, each ellipsoid, ± 6–7 cm long, 3 cm wide, rostrum 1.5 cm long, sessile, glabrous, slightly warty, particularly in distal portion, 6–12-seeded.
    Seeds
    Seeds red, angular, ± 9–11 mm diameter.
    Ecology
    Evergreen forest; 900–2100 m
    Conservation
    C. stelechantha is known from 14 specimens and ± seven sites, most of which are forest reserves and therefore, protected to an extent. It seems restricted to the Udzungwa Mts where it is relatively common between 900–2000 m. Forest in this area is threatened by wood extraction (Frimodt-Moeller pers. comm.), so the species is here assessed as VU B2a, b(iii), i.e., vulnerable.
    Note
    Very closely related (the “ C. stelechantha group”) to C. porphyrantha Brenan, C. rondoensis Cheek, C. quentinii Cheek and C. lukei Cheek, but distinct in the characters stated in the key. These five species are unique in East Africa in bearing flowers on the trunk and main branches, rather than bearing axillary flowers, also in that the perianth in the male flower is held flat, rather than being campanulate, finally in that the stigmas in the female flowers are white, papillate, reflexed, and ± obovate (where known). In describing C. lukei as a new species, I erred in describing the range of variation in outer perianth indumentum of C. stelechantha, and in stating that it had 3–4 carpels. It usually has 5.
