Tribulus pentandrus is a species of flowering plant in the caltrop family (Zygophyllaceae). It's also known as "five-stamen caltrop". Findings in Qatar indicate that it grows as a prostrate herb with spiny fruit, often found in sandy or dry areas. However, I could not verify any further information regarding its distribution within the country.

Observations took place over a period of time, from March 2014 to August 2015, indicating the plant's presence and growth patterns in Qatar. The plant was found in areas with center-pivot irrigation, suggesting it can thrive in such conditions. Overall, Tribulus pentandrus appears to be a robust and adaptable species in Qatar's environment. Its growth and reproduction were documented through various photographs.
