Botanical Identification
Ecology
The ecology of Eleusine coracana is characterized by its ability to thrive within specific altitudinal and environmental parameters, primarily occupying anthropogenic areas (Área Antrópica) and the Cerrado biome (latu sensu). This species demonstrates a broad vertical distribution, inhabiting diverse landscapes across an elevational range that extends from a minimum of 1100 m AMSL to a maximum of 2600 m AMSL. Its presence in disturbed or human-modified environments alongside the native savanna ecosystems of the Cerrado highlights its adaptability to varying soil conditions and land-use patterns within these highland regions.
- Elevational range max:
- 2600 m AMSL
- Elevational range min:
- 1100 m AMSL
- Habitat :
- Área Antrópica, Cerrado (lato sensu)
Life history
The life history of Eleusine coracana is characterized by an annual lifecycle, meaning the plant completes its entire developmental process—from germination to seed production—within a single growing season. In terms of its botanical life form, it is classified as a therophyte, a strategy where the plant survives unfavorable environmental conditions by persisting as a seed, with the vegetative body dying off after maturity. This classification is consistent across its morphological descriptions, identifying it as a therophyte that relies on rapid seasonal growth to reach reproductive maturity before the onset of senescence.
- Life form :
- therophyte
- Lifecycle :
- annual
Morphology
The morphology of Eleusine coracana is characterized by its growth form as a graminoid herb, exhibiting a non-woody structure that is entirely self-supporting rather than acting as a climber or liana. As a terrestrial plant, it functions as an independent organism, lacking any parasitic or epiphytic tendencies. The plant maintains a relatively modest stature, with an average height of approximately 0.3 m, though it can reach a maximum height of up to 1.5 m depending on environmental conditions.

Physiology
The physiology of Eleusine coracana is characterized by a highly efficient metabolic framework, most notably its utilization of the C4 photosynthetic pathway. This specialized carbon fixation mechanism allows the plant to concentrate carbon dioxide within bundle sheath cells, significantly reducing photorespiration and enabling efficient biomass production even under high temperatures and intense light intensities. Furthermore, regarding its nutrient acquisition strategies, Eleusine coracana is not a nitrogen fixer; it lacks the symbiotic relationship with nitrogen-fixing bacteria required to convert atmospheric nitrogen into usable forms, meaning it relies primarily on the uptake of nitrates and ammonium from the soil to meet its nitrogen requirements for protein synthesis and growth.
- Nitrogen fixer :
- no
- Photosynthetic pathway :
- C4
Reproduction
Reproduction in Eleusine coracana is characterized by an abiotic pollination syndrome, specifically relying on wind to facilitate the transfer of pollen. The plant is capable of self-fertilization, ensuring reproductive success even in isolated conditions. The resulting fruits are classified as dry, containing seeds with a highly consistent volume of 2.1 mm³, as both the minimum and maximum recorded seed volumes are 2.1 mm³. The mass of these seeds varies slightly, with a minimum value of 0.00209 g, a maximum of 0.00241 g, and an average seed mass of 0.0023 g.
