Botanical Identification
Ecology
The ecology of Combretum imbérbe is characterized by its broad adaptability to varying topographical gradients, allowing it to occupy diverse landscapes across its native range. This species thrives within a significant altitudinal spectrum, establishing itself in habitats ranging from low-lying areas at an elevation of 185 m AMSL to more elevated terrains reaching up to 1650 m AMSL. This wide elevational range suggests a high degree of ecological plasticity, enabling the plant to colonize different microclimates and vegetation zones, from lowland savannas to more montane woodland environments.
- Elevational range max:
- 1650 m AMSL
- Elevational range min:
- 185 m AMSL
Life history
The life history of Combretum imbérbe is characterized by its status as a perennial species, allowing it to maintain its presence within its ecosystem over many successive growing seasons. As a perennial woody plant, it exhibits a deciduous habit, meaning it undergoes a seasonal shedding of its foliage, typically in response to environmental cues such as the onset of a dry season. This cyclical shedding of leaves is a strategic survival mechanism that helps the plant conserve moisture and manage resources during periods of water scarcity.

- deciduous
- Lifecycle :
- perennial
Morphology
The morphology of Combretum imbérbe is characterized by a robust growth form, primarily manifesting as a woody tree. It functions as an independent organism, neither acting as a parasite nor an epiphyte, and maintains a terrestrial habitat. The plant is self-supporting rather than behaving as a liana or a climbing vine. In terms of stature, it reaches significant dimensions, with a plant height that typically ranges from a minimum of 7 m to a maximum of 15 m, maintaining an average height of approximately 10 m.

Physiology
The physiology of Combretum imbérbe is characterized by a specific metabolic framework and nutrient acquisition strategy. It utilizes the C3 photosynthetic pathway, a common mechanism in many woody species where carbon dioxide fixation occurs primarily through the enzyme RuBisCO within the mesophyll cells. Furthermore, this species is not a nitrogen fixer, meaning it lacks the symbiotic relationship with diazotrophic bacteria required to convert atmospheric nitrogen into usable forms, and instead relies on the uptake of nitrogenous compounds available within the soil matrix.
- Nitrogen fixer :
- no
- Photosynthetic pathway :
- C3
Reproduction
The reproduction of Combretum imbérbe is characterized by the production of seeds with specific morphological and physical dimensions. These seeds exhibit a consistent volume, measured at exactly 69 mm³ across the recorded range, indicating a lack of variance in seed size. However, the mass of the seeds shows a degree of variability, with values ranging from a minimum of 0.03844 g to a maximum of 0.09918 g. This fluctuation in weight results in an average seed mass of 0.06611 g, reflecting the specific energetic investment the plant makes during its reproductive cycle.
- Seed mass max:
- 0.09918 g
- Seed mass mean:
- 0.06611 g
- Seed mass min:
- 0.03844 g
- Seed volume max:
- 69 mm³
