Botanical Identification

Ecology

The ecology of Syzygium claviflorum is characterized by its specific distribution within low-to-mid altitude tropical ecosystems. This species primarily thrives in environments situated at a mean elevation of 200 m AMSL, with its recorded presence starting from a minimum baseline of 200 m AMSL. While it is most commonly found in these lower elevations, its ecological niche extends vertically up to a maximum elevation of 1000 m AMSL. This altitudinal range suggests a preference for humid, lowland, or sub-montane habitats where it can adapt to varying topographical gradients within its established environmental constraints.

Elevational range max:

1000 m AMSL

Elevational range mean:

200 m AMSL

Life history

The life history of Syzygium claviflorum is characterized by its status as a perennial organism, ensuring its presence in the ecosystem over many successive growing seasons. As a phanerophyte, the plant maintains its photosynthetic organs on elevated woody structures, a life form that allows it to thrive within its specific ecological niche. Furthermore, it exhibits an evergreen deciduousness pattern, meaning it retains its foliage throughout the year rather than shedding it seasonally, contributing to its continuous metabolic activity and structural stability.

Deciduousness :

evergreen

Life form :

phanerophyte

Lifecycle :

perennial

Morphology

The morphology of Syzygium claviflorum is characterized by its robust growth form as a woody tree. This species is a terrestrial, self-supporting plant that does not function as a climber, liana, or vine, nor does it exhibit epiphytic or parasitic behaviors, maintaining an independent life cycle. In terms of stature, the plant displays significant vertical development, with a height ranging from a minimum of 3 meters to a maximum of 15 meters, though it can reach an average height of approximately 20 meters.

Physiology

The physiology of Syzygium claviflorum is characterized by a C3 photosynthetic pathway, which dictates its metabolic processes and carbon fixation efficiency. The vegetative structure features leaves that exhibit significant morphological variation, with a mean leaf length of 14.25 cm and a minimum length of 9 cm, reaching a maximum of 21 cm. The leaf width also shows a broad range, maintaining a mean of 4.25 cm with a minimum width of 3.5 cm and a maximum width of 8 cm. Furthermore, this species does not function as a nitrogen fixer, relying instead on external soil nutrient availability rather than symbiotic nitrogen fixation to support its physiological development.

Reproduction

The reproduction of Syzygium claviflorum is driven by biotic pollination syndromes, specifically relying on insects and bees to facilitate the transfer of pollen. The flowering process is characterized by inflorescences that are relatively small, ranging in length from a minimum of 0.015 m to a maximum of 0.02 m. Following successful pollination, the plant produces fruit with varying dimensions; the fruit length typically averages 1.375 cm, with a range spanning from 1 cm to a maximum of 2 cm, while the fruit width averages 0.6 cm, ranging from a minimum of 0.5 cm to a maximum of 0.8 cm. The reproductive cycle concludes with the development of seeds, which exhibit a consistent mass of approximately 0.232318 g, representing both the mean and the maximum/minimum recorded values for the species.
