Commiphora sinuata

Origin
Commiphora orbicularis is endemic to Madagascar, specifically found in the western and southern regions of the island. It was officially described by Engl. and later revised by J.B. Gillett. It is a signature species of the Malagasy dry forest flora.

Habitat
In its natural environment, this species thrives in dry deciduous forests and limestone regions (Tsingy). It is often found growing in well-drained sandy soils or rocky crevices at altitudes ranging from sea level to 400 meters. The habitat is characterized by a harsh, semi-arid climate with a distinct prolonged dry season, which the plant survives by entering a state of leafless dormancy.

Description
Commiphora orbicularis is a highly ornamental pachycaul shrub or small tree, prized for its "bonsai-ready" form and attractive foliage.

Trunk & Bark: It develops a swollen, succulent trunk (pachycaul) that can reach several meters in height in the wild but remains compact in cultivation. The bark is a highlight—typically grayish to yellowish-white, it peels away in thin, papery flakes, revealing a fresh green photosynthetic layer beneath.

Foliage: The most distinctive feature is its orbicular (round) to broadly ovate leaves. The leaves are bright green, slightly fleshy, and often have a pleasant resinous fragrance when crushed, typical of the Burseraceae family.

Flowers: It is a dioecious species (male and female flowers on separate plants). The flowers are small, greenish-red or yellowish, and emerge in clusters.

Cultivation: This is a slow-growing and resilient species. It requires full sun to encourage a thick, squat trunk and excellent drainage provided by a mineral-heavy substrate. It is deciduous and must be kept warm and almost completely dry during its winter dormancy to prevent root rot.
