Botanical Identification

Ecology

The ecology of Aerva javaica is characterized by its adaptation to specific altitudinal and environmental niches, typically thriving within an elevational range that extends from a minimum of 600 m AMSL to a maximum of 1500 m AMSL. This species demonstrates a notable preference for coastal and shoreline environments, frequently colonizing vegetated beaches where it can establish itself within the specialized ecosystems of the littoral zone.

Elevational range max:

1500 m AMSL

Elevational range min:

600 m AMSL

Habitat :

vegetated beaches

Life history

The life history of Aerva javanica is characterized by its classification as a perennial plant, allowing it to persist through multiple growing seasons. In terms of its structural growth habit and survival strategy, the species is identified as a chamaephyte, a life form where the majority of the plant's regenerative buds are located close to the soil surface. This specific growth pattern enables the plant to withstand various environmental stressors by maintaining its vital organs near the ground level.

Life form :

chamaephyte

Lifecycle :

perennial

Morphology

The morphology of Aerva javanica is characterized by a growth form that ranges from a herb to a subshrub, exhibiting a non-woody structure. This plant functions as an independent organism, neither acting as a parasite nor an epiphyte, and is strictly terrestrial in its habitat. It is a self-supporting plant rather than a liana or vine, maintaining its structure without the need for external support. In terms of stature, the plant reaches a minimum height of 0.3 m, with a mean height of approximately 1.5 m, and can attain a maximum height of up to 1.6 m.

Physiology

The physiology of Aerva javanica is characterized by specific metabolic and morphological adaptations, most notably its utilization of the C4 photosynthetic pathway, which allows for efficient carbon fixation and enhanced resource use efficiency under varying environmental conditions. The vegetative development of the plant is marked by leaves that exhibit significant morphological variability, with leaf lengths ranging from a minimum of 2 cm to a maximum of 7 cm. Furthermore, in terms of its nutrient cycling capabilities, the plant does not function as a nitrogen fixer, relying instead on external nitrogen availability within the soil to support its growth and physiological processes.

Leaf length max:

7 cm

Leaf length min:

2 cm

Nitrogen fixer :

no

Photosynthetic pathway :

C4

Reproduction

The reproduction of Aerva javaica is characterized by a specific seasonal flowering pattern and specialized seed dispersal mechanisms. The plant's flowering period typically begins in February and concludes in March, though the timing can be variable depending on environmental conditions. During the reproductive phase, the species does not exhibit self-fertilization, as the trait is documented as absent, suggesting a reliance on cross-pollination. The production of seeds is marked by very low mass values, with a mean seed mass of 0.000342 g, a minimum mass of 0.00017 g, and a maximum mass of 0.000984 g. Once the seeds are mature, they are distributed via an anemochorous dispersal syndrome, meaning they are primarily dispersed by the wind.
