    Habit
    Monoecious evergreen trees with stellate indumentum
    Wood
    Wood deep yellow-brown; twigs terete, inconspicuously lenticellate, with bud-scale scars congregated at intervals
    Leaves
    Leaves papery, sometimes in intermittent clusters on branches, alternate, simple, entire, pinnately nerved, the tertiary veins reticulate, conspicuous and raised below; petiole swollen and kneed at base and apex, both long and short on same stem; stipules linear or filiform
    Flowers
    Flowers brittle, single, or few-fascicled and then only one flower open at a time, borne amongst the leaves, below the leaves or ramiflorous, subtended by 4–10 spirally inserted cup-like or flattened, ovate to oblong bracts; pedicel inconspicuous; perianth actinomorphic, uniseriate, the exterior densely pubescent, proximal half cylindrical or cup-shaped, the distal half divided into eight membranously margined ovate-triangular lobes Male flowers with anthers included in the perianth tube, androgynophore stout, bearing 12–20 elongated anthers on the periphery of a disc-like head; carpels vestigial. Female flowers with androgynophore short, bearing presumed non-functional anthers at the base, ovary a globose head of 8–30 spirally arranged pubescent, stipitate, ellipsoid-cylindrical carpels; carpels with 5–10 anatropous ovules arranged in two ranks on the ventral wall
    Male
    Male flowers with anthers included in the perianth tube, androgynophore stout, bearing 12–20 elongated anthers on the periphery of a disc-like head; carpels vestigial.
    Female
    Female flowers with androgynophore short, bearing presumed non-functional anthers at the base, ovary a globose head of 8–30 spirally arranged pubescent, stipitate, ellipsoid-cylindrical carpels; carpels with 5–10 anatropous ovules arranged in two ranks on the ventral wall
    Fruits
    Fruit with up to 30 carpels in a dense globose capitulum; carpels shortly cylindrical to ellipsoid or obovoid, pericarp indehiscent, leathery-fleshy, pubescent, containing 1–3 seeds
    Seeds
    Seeds glossy, black, ellipsoid, usually faceted by mutual compression, testa thin and fleshy, hilum large and circular; cotyledons thick, subequal, endosperm absent, radicle proximal to hilum.
    Note
    Octolobus is closely related to Cola, indeed, they are vegetatively indistinguishable, but distinct in the cylindrical perianth tube (absent or saucer-like in Cola, the (7–)8-lobed perianth (versus 5(–6)lobed) and the numerous, spirally arranged carpels (versus 4–6 in one whorl).
