Botanical Identification

Ecology

The ecology of Andira inermis is characterized by its broad adaptability across diverse altitudinal gradients, spanning an elevational range from 0 to a maximum of 2000 m AMSL. This species typically finds its primary niche within forest habitats, where it integrates into the complex structural layers of the ecosystem. Its ability to thrive from sea level up to high-altitude montane environments allows it to occupy various ecological zones, playing a significant role in the composition of forest communities across these varying elevations.

Elevational range max:
2000 m AMSL
Elevational range min:
0 m AMSL
Habitat :
forest

Life history

The life history of Andira inermis is characterized by its status as a perennial species, ensuring its long-term presence within its ecological niche. As a phanerophyte, it maintains its photosynthetic organs well above the ground, a growth form that is further categorized by its classification as a phanerophyte under both life form assessments. This plant exhibits an evergreen deciduousness, meaning it retains its foliage throughout the year rather than shedding it seasonally, allowing for continuous metabolic activity. This combination of a perennial lifecycle, phanerophyte life form, and evergreen nature defines its enduring and stable developmental strategy.

Deciduousness :
evergreen
Life form :
phanerophyte
Lifecycle :
perennial

Morphology

The morphology of Andira inermis is characterized by its robust growth form as a woody tree. It is a terrestrial species that functions as an independent organism, rather than acting as a parasite or an epiphyte. The plant exhibits significant vertical development, with height measurements ranging from a minimum of approximately 6.10 meters to a maximum of 35 meters, maintaining an average height of roughly 19.87 meters. In terms of structural support, it is classified as a self-supporting plant, possessing the necessary woodiness to maintain its stature without the need for climbing or liana-like behavior.

Physiology

The physiology of Andira inermis is characterized by a C3 photosynthetic pathway, which dictates its carbon fixation processes and metabolic efficiency. The plant exhibits specific leaf morphological traits, maintaining a consistent Leaf Dry Matter Content (LDMC) of 405.8 mg/g across its observed range (min, mean, and max), suggesting a stable investment in leaf structural density. This density is further reflected in its Specific Leaf Area (SLA), which remains constant at 109.9 cm²/g (min, mean, and max), indicating a uniform leaf thickness and resource allocation strategy. Additionally, the species possesses the physiological capacity to function as a nitrogen fixer, enabling it to enhance soil fertility through biological nitrogen fixation.

Reproduction

The reproduction of Andira inermis is characterized by a biotic pollination syndrome, primarily mediated by insects. The plant exhibits a lack of self-fertilization, suggesting a reliance on cross-pollination to maintain genetic diversity. Following successful fertilization, the plant produces seeds that vary in length, ranging from a minimum of 15 mm to a maximum of 30 mm, with an average seed mass of approximately 2.387 g. The dispersal of these seeds follows a zoochorous syndrome, meaning they are distributed via animals, which plays a critical role in the expansion of the species' range.
