Botanical Identification
Life history
The life history of Khaya senegalensis is characterized by its status as a perennial organism, allowing it to persist in its ecosystem over many years. As a phanerophyte, its regenerative buds are located high above the ground on woody branches, a structural adaptation that defines its growth habit and survival strategy. This phanerophyte classification is consistent across its developmental stages, ensuring that its vital parts remain protected and elevated as it matures into a substantial tree within its natural habitat.
- Life form :
- phanerophyte
- Lifecycle :
- perennial
Morphology
The morphology of Khaya senegalensis is characterized by its stature as a large, woody tree that functions as a self-supporting growth form. It is a terrestrial species, existing independently of any parasitic or epiphytic relationships. The plant exhibits significant vertical development, with an average height of approximately 25 m and the capacity to reach a maximum height of up to 30.48 m. As a self-supporting woody tree, it does not exhibit climbing behaviors such as lianas or vines, nor does it occupy aquatic or semi-aquatic niches.

Physiology
The physiology of Khaya senegalensis is characterized by a C3 photosynthetic pathway, which involves the direct fixation of atmospheric carbon dioxide through the Calvin cycle within the mesophyll cells. As a member of the Meliaceae family, it does not possess the specialized anatomical adaptations seen in C4 or CAM plants, instead relying on the standard enzymatic activity of RuBisCO for carbon assimilation. Furthermore, this species is not a nitrogen fixer, meaning it lacks the symbiotic relationship with nitrogen-fixing bacteria (such as Rhizobium) required to convert atmospheric nitrogen into bioavailable forms; consequently, its growth and metabolic processes are heavily dependent on the availability of inorganic nitrogen sources, such as nitrates and ammonium, within the soil matrix.
- Nitrogen fixer :
- no
- Photosynthetic pathway :
- C3
Reproduction
The reproduction of Khaya senegalensis is characterized by the production of seeds that exhibit significant variability in size and weight. The seed mass within this species shows a wide range, with a minimum recorded weight of 0.04 g and a maximum weight reaching up to 0.62 g. On average, the seed mass is approximately 0.23654875 g, reflecting a diverse distribution of reproductive units essential for the species' dispersal and establishment in its natural habitat.
