    Burseraceae, H. Wild. Flora Zambesiaca 2:1. 1963

    Habit
    Dioecious (rarely monoecious) shrubs or trees, often spiny; bark papery or smooth, often secreting an odoriferous resin.
    Leaves
    Leaves usually grouped at the ends of the branches, alternate, petiolate or more rarely sessile, 1-foliolate or 3-foliolate or imparipinnate or rarely simple; leaf or leaflet margins entire or variously dentate, surface usually reticulately veined below.
    Inflorescences
    Inflorescences often appearing before the leaves, of axillary ± elongated paniculate sometimes dichasial cymes or ± reduced to abbreviated usually 1–2-flowered axillary cymes often borne on abbreviated side-shoots.
    Flowers
    Flowers small, unisexual or more rarely apparently bisexual.
    Calyx
    Calyx narrowly infundibuliform, cylindric, campanulate or broadly campanulate, with 4 valvate persistent lobes.
    Corolla
    Petals 4, valvate, straight, spreading or recurved at the apex and the latter usually somewhat hooded and mucronulate.
    Stamens
    Stamens 8 (vestigial in female flowers), inserted just outside the disk, antisepalous ones longer; filaments subterete or broadened and flattened towards the base; anthers oblong, those of the shorter stamens usually mucronulate.
    Disc
    Disk apparently absent (lining the calyx-tube) or of 8 small lobes alternating with the stamens or of 4 lobes opposite the longer stamens (not so well developed in female flowers).
    Pistil
    Ovary (absent or rarely vestigial in male flowers), 2 (3)-locular with 2 ovules per loculus; style very short; stigma capitate, obscurely 4-lobed.
    Fruits
    Fruit an ovoid or ellipsoid or globose drupe; exocarp ± fleshy or occasionally leathery, resinous, splitting when ripe into 2 longitudinal valves (4 valves in a few species outside our area); mesocarp forming a pseudaril intimately clasping the endocarp or part of the endocarp, very variable in shape (rarely apparently absent); endocarp crustaceous or bony, smooth or rugose, enclosing one fertile loculus and a smaller abortive loculus.
    Seeds
    Seed with a straight embryo; cotyledons much folded.

    Burseraceae, J.B. Gillett. Flora of Tropical East Africa. 1991

    Habit
    Small or medium-sized trees or shrubs, usually imperfectly dioecious, rarely monoecious
    Stem
    Outer bark of trunk and large branches usually translucent and peeling away from the green under-bark.
    Exudate
    Exudate a gummy resin or liquid and volatile, often aromatic, the exudate may be copious, scanty or hardly apparent; it is not clear whether this is a genetically based character, more or less constant for each taxon or dependent on edaphic or seasonal factors.
    Wood
    Wood soft, light, sometimes used by pastoralists to make household utensils.
    Branches
    Ultimate branches either long-shoots on which the leaves are spirally arranged or condensed short-shoots bearing leaves in clusters; either long- or short-shoots or both may or may not be spine-tipped; flowers usually produced on short-shoots
    Leaves
    Leaves usually soon caducous, usually 3-foliolate or imparipinnate with (in Flora area) strictly opposite leaflets, less often 1-foliolate or simple; long-shoot leaves often with more leaflets than short-shoot leaves
    Inflorescences
    Inflorescences, which are often precocious, maybe elongated panicles or dichasial cymes or reduced to few-flowered clusters or single flowers; ♂ inflorescence often larger and looser than the 9- Flowers pedicellate or sessile, small, regular, greenish yellow or dark red, usually imperfectly unisexual, the ♂ with or without a vestigial, rarely functional, ovary, the ♀ with reduced, occasionally functional, stamens
    Receptacle
    Receptacle flat (fig. 6/3, p.34), saucer- (fig. 7/5, p.41), cup- (fig. 12/4, p.69) or funnel-shaped (fig. 12/11)
    Calyx
    Calyx cup-shaped or tubular, with 4 or very rarely 5 valvate lobes
    Corolla
    Petals 4 or very rarely 5, free, valvate, or slightly imbricate
    Stamens
    Stamens 8 in two whorls of 4 or, in a few species, 4 only, shorter than, or, rarely, as long as the petals
    Disc
    A lobed disc is usually present
    Pistil
    Ovary 2- or very rarely, 3-locular, with 2 pendulous ovules in each locule; style short; stigma subcapitate, obscurely 4-lobed
    Fruits
    Fruit a drupe, the fleshy or leathery pericarp composed of fused ectocarp and mesocarp splitting when ripe into 2 or, less often, 4 or very rarely 3 valves to disclose the hard stone (putamen) which is usually covered, at least at the base, by a fleshy variously lobed red, orange or yellow pseudaril (which has wrongly been called the mesocarp but is really an outgrowth of the endocarp); this attracts birds thus assisting the dispersal of the stone; the stone usually consists of a fertile 1-seeded locule and a sterile locule; in a few species both locules may sometimes, or perhaps always be fertile; in a few species 3 fertile locules have been recorded as a rare abnormality; the fertile locule may show an oval ‘shield of dehiscence’ extending downwards from the apex which splits open in germination; two apical pits between the locules may or may not be present, these probably assist the absorption of water before germination
    Seeds
    Cotyledons (where observed), flat or plicate, entire, ± as broad as long (see fig. 3/3, p.10)
