Botanical Identification

Life history

The life history of Walsura robusta is characterized by its existence as a perennial species, allowing it to persist in its environment through multiple growing seasons. Throughout its lifespan, the plant maintains an evergreen habit, retaining its foliage year-round rather than shedding it seasonally.

Deciduousness :

evergreen

Lifecycle :

perennial

Morphology

The morphology of Walsura robusta is characterized by its robust growth form as a woody tree. It reaches significant dimensions in the forest canopy, with a mean plant height of approximately 20 m and a maximum potential height of up to 25 m. Although some botanical classifications may associate certain members of its genus with climbing habits, this specific species functions as a self-supporting structure rather than an obligatory or facultative liana or vine.

Physiology

The physiology of Walsura robusta is characterized by its metabolic processes and nutrient acquisition strategies typical of large, deciduous forest trees. As a member of the Meliaceae family, its physiological functions are geared toward supporting significant biomass production and structural stability. Regarding its relationship with soil nutrients, the plant does not function as a nitrogen fixer; it lacks the symbiotic relationship with diazotrophic bacteria, such as Rhizobium, required to convert atmospheric nitrogen into bioavailable forms. Instead, its nitrogen requirements are met through the uptake of nitrates and ammonium from the soil via its extensive root system. The plant's water relations and photosynthetic efficiency are adapted to seasonal shifts, allowing it to manage transpiration rates and carbon assimilation in response to varying moisture availability in its natural habitat.

Nitrogen fixer :

no

Reproduction

The reproduction of Walsura robusta is characterized by the development of specialized fruit structures and specific seed metrics. The plant produces fruits that exhibit a fleshy consistency, transitioning through states of fruit dryness that can be described as both fleshy and dry depending on the stage of maturation. The seeds produced within these fruits are remarkably uniform in size, maintaining a consistent seed volume across the population. Specifically, the seed volume remains constant with a minimum, maximum, and mean value of 440 mm³, ensuring a standardized reproductive output for the species.
