Commiphora mollis

Geographic & Climate

• Geographic Coordinates: 2° S – 25° S, 12° E – 40° E (Native range across Sub-Saharan & Southern Africa; Type locality: Mozambique)

• Climate Classification: Tropical Savanna / Semi-Arid Tropical Climate (Köppen: Aw / BSh)

• Habitat Characteristics: Native to dry deciduous woodlands, open thornveld, and rocky granite or limestone outcrops at elevations from 100 m to 1,500 m above sea level. Thrives in shallow, highly permeable sandy or stony substrates that experience prolonged dry seasons.

Botanical Morphology

• Diagnostic Features: Unarmed (entirely spineless, distinguishing it from most spiny Commiphora species). Thick, pachycaul trunk with smooth, silver-grey to brownish bark that peels in thick, papery plates to reveal a green, photosynthetic cortex underneath. Leaves are imparipinnate (with 2–6 pairs of opposite leaflets plus one terminal leaflet) and covered in a dense, soft, velvety pubescence on both surfaces. Inflorescences are small axillary clusters of yellowish-pink 4-merous flowers appearing before or alongside new foliage. The fruit is a globose, densely hairy drupe (~1 cm in diameter) that splits when mature to reveal a single black seed partially enclosed by a 4-lobed, bright red pseudo-aril.

• Growth Habit: Deciduous pachycaul shrub or small-to-medium tree reaching 4 to 8 meters in height. Strictly dry-season dormant, shedding all foliage to conserve moisture. Displays a slow to moderate growth rate.

History & Etymology

• Etymology: The genus name Commiphora derives from the Ancient Greek kommi (gum or resin) and phora (bearer), referring to its aromatic resin. The specific epithet mollis is Latin for "soft," describing the dense, velvety trichomes on the foliage.

• Historical Context: First collected in Mozambique and described under the basionym Balsamodendrum molle by British botanist Daniel Oliver in 1868, the species was reclassified into Commiphora by Heinrich Gustav Adolf Engler in 1883 (Monographiae Phanerogamarum). Commonly known in Southern Africa as "Velvet Corkwood" or "Kanniedood" (Afrikaans for "cannot die") because unrooted branch cuttings easily strike roots, making it a historic choice for living fences.
