 Boswellia papyrifera is a drought-resistant tree of Central and eastern Africa and a source of frankincense.
-"... deciduous tree which can be as tall as 12 m, with a rounded crown and a straight regular bole. The bark is whitish to pale brown, peeling off in large flakes; slash red-brown and exuding a fragrant resin. The bark contains schizogenous olea-gum-resin pockets (Verghese 1988). Leaves are large, compound, arranged on long stalks with 11 to 29 leaflets which are narrowly ovate to oblong, waved or toothed along the margin. B. papyrifera is a monocious species with sweet scented flowers which are white to pink, arranged on long red flower stalks, in loose panicles at the end of branches. Fruits are obtetrahedral, which are red capsules about 2 cm long, usually containing three tapered seeds." \\
