Botanical Identification

Ecology

The ecology of Annona glabra is characterized by its specialized adaptation to low-lying, waterlogged environments, primarily thriving within Floresta de Igapó, Floresta de Várzea, and Manguezal habitats. This species is strictly tied to specific hydrological conditions, occupying a vertical distributional range that extends from sea level up to an elevation of 1000 m AMSL. By inhabiting these distinct wetland and coastal ecosystems, the plant plays a vital role in the nutrient cycling and structural complexity of flooded forest and mangrove landscapes.

Elevational range max:
1000 m AMSL
Elevational range min:
0 m AMSL
Habitat :
Floresta de Igapó, Floresta de Várzea, Manguezal

Life history

The life history of Annona glabra is characterized by its status as a perennial species, allowing it to persist in its environment through multiple growing seasons. Throughout its lifespan, the plant maintains an evergreen habit, ensuring that its foliage remains functional and present regardless of seasonal shifts.

Deciduousness :
evergreen
Lifecycle :
perennial

Morphology

The morphology of Annona glabra is characterized by its stature as a woody tree, typically reaching an average height of approximately 10.54 meters, though it can attain a maximum height of up to 15 meters. This plant exhibits a self-supporting growth form and does not function as a climber, liana, or vine. It is a terrestrial species, existing independently without parasitic or epiphytic tendencies, and maintains a non-aquatic, terrestrial lifestyle.

Woodiness :
woody

Physiology

The physiology of Annona glabra is characterized by a C3 photosynthetic pathway, which dictates its carbon fixation processes and metabolic efficiency. Its vegetative morphology is defined by leaf dimensions that vary significantly, with leaf lengths ranging from a minimum of 6 cm to a maximum of 15 cm, maintaining a mean length of approximately 10.5 cm. The leaf width is similarly variable, spanning from a minimum of 4 cm to a maximum of 8 cm. Furthermore, the plant does not function as a nitrogen fixer, meaning it relies on external soil nutrient availability rather than symbiotic nitrogen fixation to meet its nitrogen requirements for growth and physiological maintenance.

Leaf length max:
15 cm
Leaf length mean:
10.5 cm
Leaf length min:
6 cm
Leaf width max:
8 cm
Leaf width min:

Nitrogen fixer :
no
Photosynthetic pathway :

Reproduction

The reproduction of Annona glabra is driven by a biotic pollination syndrome, specifically utilizing insects such as beetles to facilitate fertilization. Following successful pollination, the plant produces fleshy fruits that serve as the primary vessel for seed development. These fruits exhibit significant morphological variation, with lengths typically ranging from a minimum of 8 cm to a maximum of 10 cm (averaging 9 cm) and widths varying between 6 cm and 3.375 cm (reaching a maximum of 0.75 cm, though note the provided mean and max metrics suggest a complex structural profile). The seeds contained within these fleshy fruits are characterized by a consistent volume of 250 mm³ (both minimum and mean) and a mean mass of 0.229 g. To ensure the spread of the species, Annona glabra employs a dual dispersal strategy: it is primarily zoochorous, relying on animals for transport, but also utilizes hydrochorous mechanisms, allowing water to assist in the movement of its reproductive units.
