Found only in Irkhaya (Irkaya) Farms, in central area of the circles.
Bidens pilosa is a species of flowering plant in the aster family, Asteraceae. It is native to the Americas but it is known widely as an introduced species of other regions, including Asia and the Pacific Islands. Its many common names include black-jack, beggar-ticks, cobbler's pegs, and Spanish needle.[+]
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.
The plant Bidens pilosa was observed growing in wet areas on Green Circles (center-pivot irrigation) in Irkhaya Farms, Qatar. It had leaves and produced flowers and fruits, with observations made over several months from February to December 2015. The plant's growth was noted in various stages, including blooming plants, flower buds, and seed heads. Close-up observations of the plant's leaves, flowers, and fruits were also made, providing detailed information about its morphology. The plant was found to thrive in wet spots on the farms, with multiple observations of its growth and development over time. Its ability to produce fruits and seeds was also documented, suggesting that it is a prolific species in the region.
