    Habit
    Evergreen tree 7–20 m tall; stems glabrous; bud-scales very early caducous, ovate, ± 3 mm long, 3 mm wide
    Leaves
    Leaf-blade elliptic, rarely slightly ovate or oblanceolate, 8–25 cm long, 2.5–10 cm wide, acumen up to 1.5 cm long, base cuneate to subcordate, glabrous, 5–6 pairs of veins; petiole terete, very variable in length, 0.5–13 cm long, 0.1–0.4 mm thick, glabrous, drying black at base and apex; stipules caducous, lanceolate, acuminate, ± 7 mm long, 1.5 mm wide, margin pubescent
    Inflorescences
    Inflorescence cauliflorous, fascicles of single flowers from short woody spur shoots ± 0.7–1.5 cm long, 0.7–1 cm wide each bearing 15–30 flowers, isolated or clustered in burrs 4–5 cm across, on both branches and trunk, bracts basal, 3–4, ± 1.1 mm long, 0.8 mm wide, rounded; pedicel 1.3–4 cm long, articulated 0.5–1 cm from the base, glabrous, bright red
    Flowers
    Flowers bright red or red-purple, rose-purple or ( Luke 1835) yellow to fleshcoloured inside, 12–16 mm across, perianth divided to within 1.5–3.5 mm of the base into 4–6 patent lobes, lobes ovate-triangular 3.5–9 mm long, 3.5–5 mm wide, often revolute, glabrous outside, minutely papillate inside Male flowers with white androphore, 1.5–2.5 mm long, 0.3–0.5 mm wide, glabrous, anthers 5–7, uniseriate, forming a ring 0.5–1 mm long, 1.2–1.5 mm thick, glabrous Female flowers as the male, but androphore absent, non-functional anthers forming a ring at the base of the ovary; ovary 3–4 lobed, very densely grey, stellately tomentose, ovoid, 1.2–2 mm long, 1.2–1.5 mm wide; stigmas ± sessile, reflexed, ± 1 mm wide
    Male
    Male flowers with white androphore, 1.5–2.5 mm long, 0.3–0.5 mm wide, glabrous, anthers 5–7, uniseriate, forming a ring 0.5–1 mm long, 1.2–1.5 mm thick, glabrous
    Female
    Female flowers as the male, but androphore absent, non-functional anthers forming a ring at the base of the ovary; ovary 3–4 lobed, very densely grey, stellately tomentose, ovoid, 1.2–2 mm long, 1.2–1.5 mm wide; stigmas ± sessile, reflexed, ± 1 mm wide

    Ecology
    Evergreen forest, often on limestone; 45–950 m
    Conservation
    The seven specimens available suggest that this spectacular species is known for certain from only two small forest sites (Longo Mwagandi in Shimba Hills and Pangani Rocks) in Kenya and one in Tanzania, at Bulwa. Protection at the first site is currently of concern due to a conflict in management (Luke pers. comm.). The Tanzanian site consists of less than 5 individuals in a 12.6 ha disturbed forest fragment near Bulwa in which this is the only Cola (Cordeiro pers. comm. 2001–2003). Although disjunct altitudinally (by ± 500 m) and geographically from the two Kenyan sites, careful comparison of the complete material obtained through Cordeiro reveals no significant morphological differences. Cola porphyrantha is here assessed as EN B2a,b(iii) i.e. Endangered. IUCN (Red List 2002, www.redlist.org) also list this species as endangered (EN B1+2c).
    Note
    Cola porphyrantha falls in the “ C. stelechantha group” (see notes under the last). The species are easily separated using the characters in the key.
    Distribution
    Flora districts: K7 T3 Range: Not known elsewhere.

    Use
    The fruits are edible ( Magogo & Glover 1080).
