Distribution

This plant exhibits a specific geographical distribution spanning across multiple regions of the African continent. In West-Central Tropical Africa, it can be found within the borders of Burundi, Rwanda, and the Democratic Republic of the Congo. Moving toward the eastern side of the continent, its range extends into Northeast Tropical Africa. Specifically, it is documented to grow in the nations of Djibouti and Eritrea. Consequently, the species occupies diverse ecological niches from the central tropics to the northeast.

Botanical Identification

Ecology

The ecology of Commiphora kua is characterized by its ability to thrive within diverse topographical settings, ranging from the moisture-retaining semi-evergreen thickets located throughout the coastal belt to the more arid, well-drained environments found on rocky slopes further inland. This distribution indicates a specialized adaptation to varying levels of humidity and soil composition, allowing the species to occupy niche environments where it can balance the influence of maritime climates with the rugged, mineral-rich terrains of interior landscapes.

Habitat :

semi-evergreen thickets in the coastal belt, and on rocky slopes inland

Life history

The life history of Commiphora kua is characterized by its status as a perennial species, allowing it to persist in its environment over many years through continuous growth cycles. As a long-lived woody plant, its developmental trajectory involves an initial establishment phase followed by a prolonged period of maturation where it develops the structural resilience necessary to survive in its specific ecological niche. Unlike annuals or biennials that complete their life cycles in a single or dual season, this perennial maintains its physiological functions across multiple years, often undergoing seasonal fluctuations in metabolic activity and resource allocation to support long-term survival and reproductive success.

Lifecycle :

perennial

Morphology

The morphology of Commiphora kua is characterized by its growth form as a woody tree, typically reaching a mean height of approximately 4 meters. As a terrestrial species, it grows in land-based environments rather than aquatic or semiaquatic habitats, and it functions as an independent organism rather than a parasite. In terms of its structural support, the plant is self-supporting and does not exhibit climbing behavior, maintaining a stable, upright stature as a true tree.

Physiology

The physiology of Commiphora kua is characterized by specific metabolic adaptations suited to its environmental niche. The plant utilizes a C3 photosynthetic pathway, a method of carbon fixation that involves the direct fixation of CO2 through the enzyme RuBisCO, which is typical for many woody species in its genus. Furthermore, Commiphora kua does not function as a nitrogen fixer, meaning it lacks the specialized symbiotic relationship with nitrogen-fixing bacteria required to convert atmospheric nitrogen into a usable biological form, relying instead on the uptake of available nitrogen from the soil.

Nitrogen fixer :

no

Photosynthetic pathway :

C3

Reproduction

The reproduction of Commiphora kua is characterized by the production of specialized seeds that exhibit specific morphological weight profiles. Quantitative analysis of the seed mass reveals a relatively small and consistent size range, which is critical for its dispersal and germination success. The mean seed mass for this species is recorded at 0.0389 g, indicating a standardized energy investment per offspring. However, there is notable individual variation within the population, with the maximum recorded seed mass reaching 0.04832 g and the minimum seed mass descending to 0.02948 g. This distribution of mass suggests a degree of phenotypic plasticity or environmental influence on the nutrient allocation during seed development.

Seed mass max:
