Australian pine, hemd, she-oak
May be C. cunninghamiana.
Casuarina equisetifolia is a she-oak species of the genus Casuarina. The native range extends from Burma and Vietnam throughout Malesia east to French Polynesia, New Caledonia, and Vanuatu, and south to Australia (north of Northern Territory, north and east Queensland, and north-eastern New South Wales). Populations are also found in Madagascar, but it is doubtful if this is within the native range of the species. The species has been introduced to the Southern United States and West Africa. It is an invasive species in Florida and South Africa.
Casuarina equisetifolia, also known as the Australian pine or beach sheoak, is a deciduous tree native to Australia and Southeast Asia. In Qatar, it has been introduced as an ornamental species and is commonly found along coastal areas and in landscaping projects. Studies have shown that C. equisetifolia has adapted well to Qatar's arid climate, tolerating high temperatures, salinity, and drought. However, its invasive potential and impact on native ecosystems are concerns, as it can outcompete indigenous vegetation and alter local habitats. Despite this, the tree is valued for its ability to stabilize sand dunes and provide shade in urban areas, making it a popular choice for afforestation efforts in Qatar.

Close up of cones of Australian pine (she-oak, Casuarina equisetifolia) taken from the ground near a road to Zubara, near a fence of Darwish Farm. Northern Qatar, February 6, 2016The plant Casuarina equisetifolia was observed in various locations across Qatar, including Doha, Al Khor, Ras Luffan, Ruwais, and Mesaieed. It was found growing on roadsides, in city parks, and along fences. The observations noted the presence of twigs, trunks, and fine greyish green needle-like foliage. Cones of the plant were also observed on the ground near a road to Zubara. The plant was seen in different seasons, including September, February, April, July, and January, indicating its ability to thrive in Qatar's climate. The observations suggest that Casuarina equisetifolia is widely distributed in Qatar and can be found in various environments, from urban areas to rural landscapes. The plant's adaptability and hardiness are evident from its presence in different parts of the country.
