AI-generated Description

Digitaria bicornis is an annual grass species native to tropical Asia and Africa. In Qatar, it has been found growing as a weed in various habitats, including sandy areas, roadsides, and cultivated fields. It thrives in the country's hot and dry climate, typically blooming from April to November. The plant can grow up to 60 cm tall, with flat or folded leaves and a distinctive inflorescence featuring paired spikelets. While not native to Qatar, Digitaria bicornis has naturalized in the region, often forming dense stands that can outcompete other vegetation for resources.
