Botanical Identification

Life history

The life history of Baccaurea motleyana is characterized by a perennial lifecycle, allowing the plant to persist and thrive in its natural habitat over many years. As a member of the phanerophyte life forms, specifically classified under both phanerophyte categories, the plant maintains its photosynthetic organs on elevated woody stems or branches well above the ground level, a structural adaptation typical of its growth habit. This perennial nature, combined with its phanerophyte stature, ensures a long-term presence within its ecosystem, facilitating continuous development and reproductive cycles throughout its extended lifespan.

Life form :

phanerophyte

Lifecycle :

perennial

Morphology

The morphology of Baccaurea motleyana is characterized by its growth form as a woody tree. This species is strictly terrestrial in its habitat, functioning as an independent organism rather than acting as a parasite or an epiphyte. In terms of stature, the plant exhibits significant height variations, with a minimum height of 6 m, a mean height of 11.5 m, and a maximum potential height reaching up to 24 m. Although it possesses the structural capacity for being self-supporting, it maintains a robust tree-like habit throughout its development.

Physiology

The physiology of Baccaurea motleyana is characterized by a C3 photosynthetic pathway, which dictates its carbon fixation processes and environmental adaptations. The vegetative morphology of the plant is defined by substantial leaf dimensions, with leaf lengths ranging from a minimum of 20 cm to a maximum of 35 cm, maintaining a mean length of 27.5 cm. Correspondingly, the leaf width varies from a minimum of 7.5 cm to a maximum of 17 cm, with an average width of 12.25 cm. Furthermore, the plant does not function as a nitrogen fixer, meaning it relies on soil-available nitrogen rather than symbiotic nitrogen-fixing mechanisms to support its metabolic requirements.

Reproduction

The reproduction of Baccaurea motleyana is characterized by specific morphological dimensions of its reproductive structures, beginning with its inflorescence, which typically ranges in length from a minimum of 0.13 m to a maximum of 0.25 m. Following successful pollination, the plant produces fruits that exhibit a mean length of 2.75 cm, with individual fruit measurements varying between a minimum of 2.5 cm and a maximum of 3 cm. The resulting seeds are highly consistent in their physical properties, maintaining a uniform mass of 0.26 g, as evidenced by the fact that the minimum, mean, and maximum seed mass values all converge at this specific measurement.
