Calligonum is a genus of plants in the family Polygonaceae with about 80 species across the Mediterranean Sea region, Asia and North America.


Plants of the Calligonum genus are shrubs, diffusely but irregularly branched, with flexuous woody branches. Leaves are simple, opposite, nearly sessile, linear or scale-like, sometimes absent or very small, linear or filiform, distinct or united with short membranous ochreae. Flowers are bisexual, solitary or in loose axillary inflorescences. Flowers have persistent, 5-parted perianths not accrescent in fruit, and 10-18 stamens with filaments connate at the base. The ovary is tetragonous.[1][2]
