Botanical Identification

Ecology

The ecology of Eugenia patriasii is characterized by its specific preference for the Floresta de Várzea habitat, where it thrives within these seasonally flooded forest ecosystems. This species occupies a relatively narrow altitudinal belt, typically found at elevations ranging from a minimum of 80 m AMSL to a maximum of 300 m AMSL.

Elevational range max:

300 m AMSL

Elevational range min:

80 m AMSL

Habitat :

Floresta de Várzea

Life history

The life history of Eugenia patriasii is characterized by its status as a perennial plant, allowing it to persist through multiple growing seasons. As a phanerophyte, it maintains its stem system above the ground, often exhibiting a life form categorized as a nanophanerophyte depending on specific growth stages or environmental conditions. This species maintains a consistent foliage profile throughout the year, as it is classified as an evergreen, ensuring that it retains its leaves across different seasons.

Morphology

The morphology of Eugenia patriasii is characterized by its growth form as a woody tree, which functions as a self-supporting organism rather than a climber or a vine. It is an independent species that does not exhibit parasitic behavior and is strictly terrestrial, lacking any epiphytic or aquatic tendencies. The plant reaches significant dimensions, with an average height of approximately 6 m, though it is capable of reaching a maximum height of up to 18 m.

Physiology

The physiology of Eugenia patriasii is characterized by a standard C3 photosynthetic pathway, a mechanism common to many woody dicotyledonous species where carbon fixation occurs primarily through the Calvin cycle within the mesophyll cells. This metabolic process involves the initial fixation of atmospheric carbon dioxide by the enzyme RuBisCO, leading to the production of three-carbon compounds. Furthermore, the plant does not function as a nitrogen fixer, meaning it lacks the specialized symbiotic relationship with nitrogen-fixing bacteria required to convert atmospheric nitrogen into bioavailable forms; instead, it relies on the uptake of nitrates or ammonium from the soil through its root system to meet its nutritional requirements for protein and nucleic acid synthesis.

Nitrogen fixer :

no

Photosynthetic pathway :

C3

Reproduction

The reproduction of Eugenia patriasii is characterized by specific seed characteristics and a distinct method of propagation within its ecosystem. The plant produces seeds with a highly consistent mass, showing no variance between the minimum, maximum, and mean values, which are all recorded at 0.66 g. Furthermore, its primary mode of propagation is governed by a zoochorous dispersal syndrome, indicating that the seeds are distributed through the actions of animals, which plays a critical role in the spatial spread and colonization of the species.

Dispersal syndrome :

zoochorous

Seed mass mean:

0.66 g
