Extract from Wikipedia article

Euphorbia prostrata is a species of euphorb known by the common name prostrate sandmat. It is native to the West Indies and certain parts of South America, but it is widely naturalized in many other parts of the world, where it can be found in varied habitat types and in many areas grows as a roadside weed. This is an annual herb producing slender prostrate stems up to about 20 centimeters long, sometimes purple-tinted in color. The oval-shaped leaves are up to a centimeter long with finely toothed edges. The inflorescence is a cyathium less than 2 millimeters wide, with white petal-like appendages surrounding the actual flowers. There are four male flowers and a single female flower, the latter developing into a lobed, hairy fruit one to two millimeters wide.

AI-generated Description

Euphorbia prostrata, also known as prostate spurge or spreading spurge, is a low-growing, annual herb native to tropical and subtropical regions. In Qatar, it has been found to thrive in disturbed areas, such as roadsides and construction sites. Studies have reported its presence in various parts of the country, including Doha and the surrounding deserts. The plant's ability to tolerate high temperatures, drought, and saline conditions makes it well-suited to Qatar's arid environment. Its small, elliptical leaves and tiny, yellowish-green flowers are characteristic features of this adaptable and invasive species.
