Botanical Identification

Life history

The life history of Lannea schimperi is characterized by its status as a perennial plant, ensuring its long-term presence within its ecological niche. As a phanerophyte, it maintains its stem or shoot system above the ground, specifically categorized under the phanerophyte life form to describe its growth habit. The plant exhibits a deciduous nature, shedding its leaves periodically as part of its seasonal biological cycle.

Deciduousness :

perennial

Morphology

The morphology of Lannea schimperi is characterized by its growth form as a woody tree. It is a terrestrial species that functions as an independent organism, meaning it is neither a parasite nor an epiphyte. In terms of physical stature, the plant exhibits significant variation in height, with a minimum recorded height of approximately 1.83 m, a maximum of about 7.62 m, and a mean height of 10 m. Despite its climbing potential in some contexts, it is classified as self-supporting rather than a liana or vine.

Physiology

The physiology of Lannea schimperi is characterized by a C3 photosynthetic pathway, utilizing the standard Calvin cycle for carbon fixation without the specialized anatomical adaptations found in C4 or CAM species. Regarding its nutrient cycling capabilities, the plant does not function as a nitrogen fixer, meaning it lacks the symbiotic relationship with diazotrophic bacteria necessary to convert atmospheric nitrogen into bioavailable forms, instead relying on the uptake of nitrogenous compounds available within the soil matrix.

Nitrogen fixer :

no

Photosynthetic pathway :

C3

Reproduction

The reproduction of Lannea schimperi is driven by biotic pollination mechanisms, specifically utilizing an insect-based pollination syndrome where bees play a key role in the transfer of pollen. This plant exhibits a lack of self-fertilization, necessitating cross-pollination to ensure genetic diversity. Following successful fertilization, the dispersal of its seeds is characterized by a zoochorous strategy, specifically through endozoochory, where seeds are dispersed after being ingested by animals.
