Gnidia

Gnidia is a genus of flowering plants in the family Thymelaeaceae. It is distributed in tropical and southern Africa and Madagascar;^[1] more than half of all the species are endemic to South Africa.^[2] Gnidia was named for Knidos, an Ancient Greek city located in modern-day Turkey.^[3]

These are perennial herbs and shrubs, sometimes with rhizomes. Most species have alternately arranged leaves, and a few have opposite leaves. The leaves are undivided and unlobed. The inflorescence is a head of a few to many flowers. The calyx is cylindrical and the colored lobes may alternate with the petals; some species lack petals.^[3] Many species are similar in appearance and difficult to tell apart.^[4]

Molecular analyses have provided evidence that the genus is polyphyletic, made up of four different lineages. They are related to the four genera Struthiola, Drapetes, Lasiosiphon, and Pimelea.^[5]

Formerly 140 to 160 species were classified in the genus.^[2][3][6] Many have been reassigned to other genera and Plants of the World Online currently accepts 104 species.^[1]
