Botanical Identification

Life history

The life history of Walsura pinnata is characterized by its nature as a perennial plant, allowing it to persist in its environment over many years. Throughout its developmental stages, it maintains an evergreen status, retaining its foliage consistently rather than shedding it seasonally.

Deciduousness :

evergreen

Lifecycle :

perennial

Morphology

The morphology of Walsura pinnata is characterized by its growth form as a woody tree, exhibiting a robust and stable structure. Although some climbing species may exhibit liana or vine-like tendencies, this plant is classified as a self-supporting organism, functioning as a self-supporting climber in certain contexts but primarily maintaining its stature as a woody tree. It reaches a significant maximum plant height of approximately 20 meters, supported by a perennial, woody stem system that distinguishes it from herbaceous or shrubby growth forms.

Physiology

The physiology of Walsura pinnata is characterized by a C3 photosynthetic pathway, which dictates its carbon fixation processes and metabolic efficiency. The plant's vegetative morphology features elliptic leaves with entire margins, lacking both leaf thorns and spines. A key physiological metric is its Specific Leaf Area (SLA), which exhibits a consistent mean, minimum, and maximum value of 161.8183857 cm²/g, reflecting its leaf mass per unit area and its strategy for light interception and resource allocation. Additionally, the species does not function as a nitrogen fixer, relying instead on external soil nitrogen availability for its nutritional requirements.
