    Type
    Type: Kenya, Kilifi District: Chasimba, Adams 124 (K!, holo.; EA iso.)
    Habit
    Evergreen shrub or tree 3–6 m tall.
    Trunk
    Trunk pale, stems 4–5 mm thick, whitish; current year’s growth pale brown, velvety tomentose, glabrous at length; bud-scales ovate, 4–5.5 mm long, 1.5–3 mm wide, acuminate, often persistent
    Leaves
    Leaf-blade ovate (smallest leaves) to obovate-elliptic (larger), 3–18(–34) cm long, 1.8–7.5(–15) cm wide, acumen 0.5–0.7 mm long, 0.3–0.4 mm wide, base cordate (smallest leaves) cuneate to rounded, veins prominent below, 6–10 pairs, glabrous above and beneath; petiole terete, 0–4(–6.3) cm long, 1.5 mm wide, the base and apex distinctly swollen and 2.5–3.5 mm wide, thickly covered in a pale brown, velvety tomentum, becoming glabrous; stipules linear, rarely narrowly rhombic, 6–8 mm long, 0.2–0.5 mm wide, tomentose, ± persistent
    Inflorescences
    Inflorescence with flowers borne with the leaves, axillary, single or rarely in fascicles, sessile.
    Bracts
    Bracts ± 4, ± orbicular, the lowest ± 3 mm long, 4 mm wide, increasing to 6 mm long and wide, outer surface tomentose, inner glossy, glabrous, dark brown.
    Pedicel
    Pedicel absent. Flowers opening yellowish, fading chocolate brown, widely campanulate, 15–19 mm long, ± 28 mm across, perianth fleshy-leathery, divided within 2–5 mm of the base into 6 lobes, lobes narrowly triangular, 10–14 mm long, 4–9 mm wide, the margin folded inwards, outer surface densely stellate-hairy, with a mixture of long, lanate, colourless hairs up to 2 mm long, and smaller stellate hairs, folded margin lacking longer hairs, inner surface with minute papillae
    Flowers
    Male flowers with androphore abruptly contracted from the base, 2–4 mm long, 3–3.5 mm across (4 mm across at the base), thickly long stellately hairy; anthers 14, uniseriate, forming a ring 2 mm long, 5.5–6 mm wide, inner surface tomentose. Female flowers without androphore; anthers at the base of the ovary; ovary subspherical, 3–4 mm long, 5–6 mm wide, densely stellate tomentose; style up to 0.5 mm long; stigmas 6, 0.5 mm long, partly reflexed, black
    Male
    Male flowers with androphore abruptly contracted from the base, 2–4 mm long, 3–3.5 mm across (4 mm across at the base), thickly long stellately hairy; anthers 14, uniseriate, forming a ring 2 mm long, 5.5–6 mm wide, inner surface tomentose.
    Female
    Female flowers without androphore; anthers at the base of the ovary; ovary subspherical, 3–4 mm long, 5–6 mm wide, densely stellate tomentose; style up to 0.5 mm long; stigmas 6, 0.5 mm long, partly reflexed, black
    Fruits
    Fruit (probably immmature) with carpels felty green-white, 2.5 cm long, 1.3–1.8 cm wide, rostrum 0.5 cm long, stipe 0.8 mm long
    Ecology
    Evergreen forest on limestone; 200–400 m
    Conservation
    Apart from the specimen from Kwale District, this species appears restricted to the forest remnants on the limestone at Chasimba. Its total area of occupancy is believed to be below the 500 km2 threshold. Only five collections are known. The main threat at Chasimba is the removal of trees for firewood and a plan to use the rock to upgrade the Kilifi to Mariakani road (Luke, pers. comm.). Cola octoloboides is here assessed as EN B2a,b(iii), i.e. Endangered. IUCN (Red List 2002) also list this species as endangered (ENB1+2c).
    Note
    Cola octoloboides is still imperfectly known: fruiting material has not been seen. The persistent bud-scales and stipules together with the persistent stem indumentum make this one of the few East African Cola species easily recognized in the sterile state. It is most closely related to C. ruawaensis (see diagnosis of that species for distinguishing characters).
