AI-generated Description

Bidens pilosa, also known as cobblestone or beggar's ticks, is an annual herb native to tropical and subtropical regions. In Qatar, it has been reported as a naturalized weed, often found in disturbed areas, roadsides, and agricultural fields. Studies have shown that B. pilosa is widely distributed in Qatar, particularly in the northern and central regions, where it can thrive in a variety of habitats, including sandy soils and saline environments. Its presence in Qatar has been noted as early as 2007, with ongoing research suggesting its potential to become an invasive species in the country's ecosystems.
