tree,African elemi); French (elemier d'Afrique,elemi de Moahum,elemi
d'ouganda); Luganda (muwafu); Swahili (mpafu,mbani); Trade name

BOTANIC DESCRIPTION
Canarium schweinfurthii is a large forest tree with its crown reaching to the
upper canopy of the forest, with a long clean, straight and cylindrical bole
exceeding 50 m. Diameter above the heavy root swellings can be up to
4.5 m. Bark thick, on young tree fairly smooth, becoming increasingly
scaly and fissured with age. The slash is reddish or light brown with
turpentine like odour, exuding a heavy, sticky oleoresin that colours to
sulphur yellow and becomes solid.
Leaves are pinnate, clustered at the end of the branches, and may be 15-
65 cm long, with 8-12 pairs of leaflets, mostly opposite, oblong, cordate at
base, 5-20 cm long and 3-6 cm broad, with 12-24 main lateral nerves on
each side of the mid-rib, prominent and pubescent beneath. The lower
leaflets are bigger than the upper ones. The lower part of the petiole is
winged on the upper side.
The creamy white unisexual flowers about 1 cm long grow in
inflorescences that stand in the axils of the leaves and may be up to 28
cm long.
The fruit is a small drupe, bluish-purple, glabrous, 3-4 cm long and 1-2 cm
thick. The calyx is persistent and remains attached to the fruit. The fruit
contains a hard spindle-shaped, trigonous stone that eventually splits
releasing 3 seeds.
Canarium comes from the vernacular name 'kenari' in the Molucca Isles.
BIOLOGY
The seeds are mainly dispersed by hornbills and elephants. Flowers are
unisexual.
