Botanical Identification
Life history
The life history of Funtumia elasticas is characterized by its existence as a perennial organism, ensuring its presence in its natural ecosystem over many successive growing seasons. As a phanerophyte, its regenerative buds are located high above the ground on woody stems, a structural adaptation that defines its growth habit and survival strategy. Furthermore, the plant maintains an evergreen deciduousness, meaning it retains its foliage throughout the year, providing a continuous photosynthetic capacity that is typical of many tropical species.
- Deciduousness :
- evergreen
- Life form :
- phanerophyte
- Lifecycle :
- perennial
Morphology
The morphology of Funtumia elasticia is characterized by its robust, woody structure, primarily exhibiting a growth form that ranges from a shrub to a substantial tree. As a self-supporting plant, it does not function as a climber or a liana, nor does it act as an epiphyte or a parasite, maintaining an independent, terrestrial existence. The plant's stature is significant, with a mean height of approximately 22.5 m, though individual specimens may reach a maximum height of about 18.288 m. This woody architecture allows it to dominate its terrestrial habitat through a sturdy, upright growth habit.

- Woodiness :
- woody
Physiology
The physiology of Funtumia elastica is characterized by a C3 photosynthetic pathway, meaning it utilizes the standard Calvin cycle to fix carbon dioxide through the enzyme RuBisCO, which is typical for many woody tropical species. In terms of nutrient acquisition and symbiotic relationships, the plant is not a nitrogen fixer, as it lacks the specialized root nodules required to host nitrogen-fixing bacteria for the conversion of atmospheric nitrogen into usable forms.
- Nitrogen fixer :
- no
- Photosynthetic pathway :
- C3
Reproduction
The reproduction of Funtumia elasticia is characterized by a highly flexible phenological cycle, as both its flowering and fruiting periods are variable and can occur across any month of the year, from January through December. This temporal variability suggests that the plant can adapt its reproductive stages to shifting environmental conditions rather than following a strict seasonal pattern. The resulting seeds are remarkably uniform in size, maintaining a consistent seed mass with a mean, maximum, and minimum value of 0.034 g. Regarding the movement of its progeny, the species utilizes an anemochorous dispersal syndrome, relying on wind currents to transport its seeds away from the parent plant to colonize new areas.
- Dispersal syndrome :
- anemochorous
- Flowering time :
- variable
- Fruiting time :
- variable
- Seed mass mean:
- 0.034 g
