Distribution

This plant exhibits a specific distribution pattern concentrated within the tropical regions of the Americas. It is found across several territories in Northern South America, including Venezuela, Guyana, and Suriname. Additionally, the species extends its range into French Guiana. Moving toward the Caribbean, its presence is also documented in the islands of Trinidad and Tobago. Consequently, its habitat is primarily defined by these interconnected coastal and mainland locations.

Botanical Identification

Ecology

The ecology of Annona exsucca is characterized by its presence across diverse tropical ecosystems, primarily inhabiting Floresta de Terra Firme, Floresta de Várzea, and the Amazônica Savanna. This distribution indicates a high level of adaptability to varying hydrological regimes, ranging from well-drained upland forests to seasonally flooded riparian environments and open savanna landscapes. The species typically occupies low-lying topographical areas, with an average elevational range centered around 100 m AMSL (meters above sea level), positioning it within the lowland tropical belts of its native range.

Elevational range mean:

100 m AMSL

Habitat :

Floresta de Terra Firme, Floresta de Várzea, Savana Amazônica

Morphology

The morphology of Annona exsucca is characterized by its growth form as a woody tree, reaching a maximum plant height of approximately 35 meters. It is a terrestrial species, functioning as an independent organism without parasitic tendencies, and does not exhibit epiphytic behavior, remaining rooted in the ground rather than growing on other plants. While it maintains a self-supporting structure, it lacks the climbing characteristics of vines or lianas, standing firmly as a large, structural component of its ecosystem.

Physiology

The physiology of Annona exsucca is fundamentally characterized by a C3 photosynthetic pathway, a metabolic strategy common to most members of the Annonaceae family. This process involves the direct fixation of atmospheric carbon dioxide by the enzyme RuBisCO within the mesophyll cells, leading to the initial formation of a three-carbon compound, 3-phosphoglycerate. Due to this C3 mechanism, the plant's metabolic efficiency and gas exchange processes are highly sensitive to environmental variables such as light intensity, temperature, and water availability. Under conditions of high irradiance or significant water stress, the plant may experience increased rates of photorespiration, as the oxygenase activity of RuBisCO becomes more prominent. Consequently, its physiological performance is closely tied to its ability to regulate stomatal conductance to balance carbon assimilation with transpirational water loss.

Photosynthetic pathway :

C3

Reproduction

The reproduction of Annona exsucca is characterized by the production of fleshy, indehiscent fruits classified as berries. These fruits typically exhibit a mean length of 1.3 cm and a mean width of 1.5 cm. The seeds contained within the fruit are uniform in size, with a consistent volume of 10 mm³ (representing the minimum, maximum, and mean values). Dispersal of the species is achieved through a zoochorous syndrome, where animals play a primary role in spreading the seeds.
