Botanical Identification

Ecology

The ecology of Pisonia acuata is characterized by its preference for specific environmental niches, primarily thriving within the Cerrado biome. It is typically found in habitats such as pastures located on saturated soil, indicating an affinity for high moisture availability and waterlogged conditions. Geographically, the species occupies a diverse altitudinal gradient, ranging from sea level up to a maximum elevation of 1000 m AMSL.

Elevational range max:

1000 m AMSL

Elevational range min:

0 m AMSL

Habitat :

Cerrado, pastures on saturated soil

Life history

The life history of Pisonia acuuleata is characterized by its nature as a perennial species, allowing it to persist in its ecosystem through multiple growing seasons. As a phanerophyte, its regenerative buds are located high above the ground on woody stems, a structural adaptation that defines its primary life form. Throughout its existence, the plant maintains an evergreen status, retaining its foliage consistently rather than undergoing seasonal shedding.

Deciduousness :

evergreen

Life form :

phanerophyte

Lifecycle :

perennial

Morphology

The morphology of Pisonia acuacleata is characterized by a woody growth form, primarily functioning as a shrub or a liana. As an obligatory climber, it exhibits a liana growth habit and is categorized as an independent organism rather than a parasite. The plant is terrestrial in nature, not possessing aquatic or epiphytic tendencies. In terms of stature, its height is variable, with recorded measurements ranging from a minimum of 2 m to a maximum of 20 m, while maintaining an average plant height of approximately 22.5 m.

Physiology

The physiology of Pisoania acuata is characterized by specific morphological and biochemical parameters that define its leaf structure and nutritional strategy. The leaves exhibit significant variability in dimensions, with a mean length of 6.5 cm, ranging from a minimum of 2 cm to a maximum of 10 cm, and a mean width of 3.25 cm, fluctuating between a minimum of 1 cm and a maximum of 5 cm. From a nutritional and metabolic standpoint, the plant maintains a consistent Leaf Dry Matter Content (LDMC) of 271.5 mg/g, as both the minimum and maximum recorded values remain at this mean, suggesting a highly stabilized ratio of organic matter to water within the leaf tissue. Furthermore, the plant does not exhibit succulence, indicating a leaf structure that is not specialized for significant water storage in fleshy tissues, and it does not function as a nitrogen fixer, relying instead on other mechanisms for nitrogen acquisition.

Reproduction

The reproduction of Pisoia acuata is characterized by a complex reproductive strategy that relies on external biological factors rather than self-pollination, as self-fertilization is notably absent in this species. The plant produces distinct fruits that vary in size, with a mean length of 1.05 cm and a range spanning from a minimum of 0.7 cm to a maximum of 1.4 cm. In terms of width, the fruits maintain a consistent measurement, with both the mean and the minimum/maximum values recorded at 0.4 cm. The dispersal of these fruits follows a zoochorous syndrome, specifically utilizing an epizoochorous mechanism, which indicates that the seeds are dispersed by attaching to the outside of animals as they move through the habitat.
