Gnidia is a genus of flowering plants in the family Thymelaeaceae. It is distributed in Africa, Madagascar, Arabia, India, and Sri Lanka; more than half of all the species are endemic to South Africa.[1] Gnidia was named for Knidos, an Ancient Greek city located in modern-day Turkey.[2]
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.[2] Many species are similar in appearance and difficult to tell apart.[3]
Molecular analyses have provided evidence that the genus is polyphyletic, made up of four different lineages. They are related to the four genera Struthiola, , Lasiosiphon, and Pimelea.[4]
There are 140 to 160 species classified in the genus.[1][2][5]
