Ziziphus nummularia, also called Jharber (Hindi: झड बेर), is a species of Ziziphus native to the Thar Desert of western India and southeastern Pakistan and south Iran (where it is called رمیلک ramilak in Persian).[+]
Ziziphus nummularia, also known as jujube or sidr, is a thorny shrub or small tree native to tropical and subtropical regions. In Qatar, it is commonly found in arid and semi-arid areas, often growing in sandy dunes and rocky outcrops. Studies have shown that Ziziphus nummularia is widely distributed in Qatar, particularly in the central and southern regions of the country. It is a drought-tolerant species, well adapted to the harsh desert conditions of Qatar, and plays an important role in stabilizing sand dunes and providing habitat for local wildlife.

A tree of Ziziphus nummularia in a silty depression in Al Nuaman (Naim tribe, Nuaimiya). Northern Qatar, December 26, 2015The plant Ziziphus nummularia was observed in various locations in Qatar, primarily in the north-western region. It was found growing on roadsides, in silty depressions, and in areas with other vegetation. The plant was often associated with other species, such as Black-eyed geranium, Corn cleavers, and Shrubby Horsetail. Observations were made over a period of nearly two years, from February 2014 to March 2016. The plant was seen in different stages of growth, including young shoots, mature bushes, and trees with fruits. In some cases, the plant was affected by pests, such as brown furry caterpillars eating its leaves and flowers. Overall, the observations suggest that Ziziphus nummularia is a common and widespread species in Qatar, able to thrive in various environments. Its growth and development were monitored over time, providing insights into its ecology and behavior.
