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 genus Calligonum 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]

The genus Calligonum was first published by Carl Linnaeus in 1753.[3] It is placed in the subfamily Polygonoideae, tribe Calligoneae, along with its sister genus, Pteropyrum.[4]
