Common carpetgrass

<em>Axonopus fissifolius</em>, commonly known as common carpetgrass, is a grass species with a broad global distribution spanning Africa, Asia, Europe, the Americas, and Oceania. It typically thrives in grasslands, wetlands, forests, and cultivated areas, often tolerating poorly drained and low-fertility soils. Common carpetgrass belongs to the genus <em>Axonopus</em> within the family Poaceae. It is a low-growing, stoloniferous grass that typically forms dense mats along roadsides, disturbed areas, lawns, and pastures in warm and humid climates. The species is frequently used as a lawn and pasture grass in tropical and subtropical regions due to its tolerance of mowing and its ability to spread vegetatively. Biological traits such as average lifespan, plant height, and biomass of this species remain poorly documented in the scientific literature. The species has not yet been formally evaluated by the IUCN, and its global conservation status therefore remains undetermined. Its widespread occurrence across multiple continents and highly varied habitats suggests strong ecological adaptability.
