Euphorbia retusa is a succulent shrub native to the Middle East and North Africa. In Qatar, it has been found growing in arid environments, often on sandy or rocky soils. Studies have reported its presence in various regions of the country, including the northern and western areas. The plant's ability to thrive in Qatar's harsh desert conditions is likely due to its adaptations, such as its succulent stems and drought-tolerant leaves. However, more specific information about its distribution, habitat, and conservation status in Qatar would require further research and consultation of local botanical studies.
Euphorbia retusa was observed in a large roadside depression near Route 77 to Ras Laffan, Qatar, on February 6 and April 16, 2016. The plant was found growing on gravel soil, and its habitat was documented with wide-angle views. The observations included photos of the plant's leaves, flowers, and fruits, as well as close-up shots of its inflorescence. The plant was in bloom in February, with yellowish-green flowers, and had developed fruits by April. The fruits were observed to be mature and ready for dispersal. Overall, the observations provided a detailed record of the plant's morphology and growth habits in its natural habitat. The plant's rarity was also noted, with multiple references to it being a "rare spurge" in the region.
