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]
The Polygonaceae are a family of flowering plants known informally as the knotweed family or smartweed—buckwheat family in the United States. The name is based on the genus Polygonum, and was first used by Antoine Laurent de Jussieu in 1789 in his book, Genera Plantarum. The name may refer to the many swollen nodes the stems of some species have, being derived from Greek [poly meaning 'many' and gony meaning 'knee' or 'joint']. Alternatively, it may have a different origin, meaning 'many seeds'.

They are annual herbs producing slender, erect, glandular stems from taproots. The leaves are located in a rosette around the base of the stem and wither quickly.
