RSA Tree No. 280.

Common names: Velvet Corkwood, Velvet-leaved Corkwood, Soft leaved Commiphora, Velvet Commiphora.

 Family: Burseraceae (frankincense from Boswellia sacra, myrrh from Commiphora myrrha). Worldwide there are about 16 genera and about 500 species. In the RSA Commiphora is the only genus and there are 31 species. Bark is smooth, aromatic and flaking. The Leaves are resinous and usually without stipules. Flowers have 4 or 5 petals and sepals that are imbricate (having regularly arranged, overlapping edges, as roof tiles). Flowers are actinomorphic (regular, symmetric) and have Stamens that have double or equal the number of petals. The superior Ovary has 3-5 carpels with 2 ovules in each and the single Style ends in a capitate (forms like a head) or lobed Stigma. The Fruit is a drupe.

 Name derivation: Commiphora Greek: kommi – gum and phora – bearer. mollissoft – referring to the soft, silky hairs on the leaves.

Conservation Status: L C. (Least Concern). 2009 (Raimondo et al.).

The Tree has many branches, a wide crown and reaches 8m high. Branches are spineless and hairy when young. The Trunk is grey or greenish grey, smooth, shiny and may be fluted. Bark that faces the sun is silvery and smooth with wrinkles around the branches where they are exposed to the sun. Here the trunk is fluted and the bark may peel off in thick discs. In branches that face away from the sun the bark is khaki-coloured and peels off in small flakes exposing the green below. Twigs (1-year-old current branch segments) extend almost at right angles to the branches and have small white dots. Brown aromatic Resin ducts are present in the bark. Watery milky sap is present.


The Leaves are almost at right angles to the branches and are Imparipinnate (pinnately compound leaf ending in a single leaflet). There are 2-6 pairs of opposite leaflets, each ending in the biggest terminal leaflet. The smallest Leaflets are closest to the petiole (leaf stalk) and are elliptic. The terminal leaflet narrows towards the base. In the paired leaflets, the Base is rounded and the Apex is pointed to rounded. Leaflets are green above, lighter and hairier below – hence the specific name. The plant is deciduous. The leaves turn yellow before falling in autumn. Margins are entire (with a continuous margin, not in any way indented). The Petiole (Leaf stalk) is 1-3cm long. Petiolules (leaflet stalks) are short or absent on lateral leaflets but visible on the terminal leaflet. Stipules (basal appendages of the petiole) are absent.


The small yellowish to pinkish Flowers are dioecious (having male and female flowers on separate plants). The buds have a long, red, slender stalk. The flowers are actinomorphic (regular, symmetrical. The Perianth, the calyx and corolla, are divisible into 3 or more identical sectors). The Calyx has 4 Sepals that have a joined base. The 4 Petals of the Corolla in this bell-shaped flower have a tubular base opening up into pink to yellow lobes. The petals alternate with the sepals. A Disc (a more or less fleshy or elevated development of the receptacle) is present. Flowers may appear before or with the new leaves. The Male flowers are usually larger than female flowers. Here a rudimentary ovary is present. In the Female flowers, a single Pistil (a unit of the Gynoecium, the female element of the flower, composed of the Ovary, Style and Stigma) is present. Here the Ovary is superior and 2-locular. (Sep-Jan).


The Fruit is pale green to brown and matures to a dull red. It is up to 1cm in diameter. This Drupe (a fleshy, 1-seeded indehiscent fruit with the seed enclosed in a stony endocarp; stone fruit e.g. peach) is hairy and attached to a stout stalk. The black Seed is almost covered the by a scarlet, 4-lobed pseudo-aril. (Feb-Apr).

Distribution & Ecology

This Tree occurs naturally in Limpopo, North West, Mpumalanga, Botswana, Mozambique, Namibia, and into tropical Africa. The Leaves act as food plants for the White Barred Gipsy Moth (Palasea albimacula). Kudu and other game browse the leaves and young Shoots. Animals dig up and eat the Roots. These trees Occur at medium to low altitudes (up to 1 500m) in hot, dry types of woodland or bushveld, on rocky outcrops and well-drained, sandy soil.


This Tree is one of the more attractive of the Commiphora species. It can best be propagated from cuttings. Leaves are browsed by stock. Wood is of little use.
