Botanical Identification

Ecology

The ecology of Pteroxygonum giraldii is characterized by its specific altitudinal distribution within its natural habitat. This species thrives across a diverse vertical gradient, occupying various ecological niches ranging from lower montane zones to higher elevations. Its elevational range begins at a minimum of 600 m AMSL and extends up to a maximum of 2000 m AMSL. On average, the species is most frequently encountered at a mean elevation of 1300 m AMSL, suggesting that its optimal environmental conditions, such as temperature regimes and atmospheric pressure, are most closely aligned with these mid-elevation settings.

Elevational range max:

2000 m AMSL

Elevational range mean:

1300 m AMSL

Elevational range min:

600 m AMSL

Life history

The life history of Pteroxygonum giraldii is characterized by its classification as a perennial organism, meaning it persists through multiple growing seasons rather than completing its cycle in a single year. As a perennial, the plant maintains a stable presence in its ecological niche, often developing robust root systems or woody structures that allow it to survive periods of dormancy or unfavorable environmental conditions. This long-term survival strategy enables the species to accumulate resources over several years, leading to repeated reproductive cycles and a sustained contribution to its population density within its natural habitat.

perennial

Physiology

The physiological characteristics of the foliage in Pteroxygonum giraldii are defined by specific morphological dimensions that dictate its surface area for photosynthetic efficiency. The leaves exhibit a variable size distribution, with a minimum leaf length of 4 cm and a mean leaf length of 5.5 cm, reaching a maximum length of 7 cm. Complementing this longitudinal variation is a distinct width profile, where the leaf width ranges from a minimum of 3 cm to a maximum of 6 cm. These dimensions contribute to the overall canopy architecture and the plant's capacity for gas exchange and light interception.

Reproduction

The reproduction of Pteroxygonum giraldii is facilitated through its specialized flowering structures, which serve as the primary mechanism for sexual propagation. The plant produces an inflorescence that is relatively compact in scale, typically measuring between a minimum of 0.02 m and a maximum of 0.05 m in length. These inflorescences house the reproductive organs necessary for pollination, supporting the transition from flower to seed production. Through this developmental process, the plant ensures genetic diversity and the eventual dispersal of offspring within its natural habitat.

Inflorescence length max:

0.05 m

Inflorescence length min:

0.02 m
