Description
editPlants 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]
Taxonomy
editThe 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]
