The genus contains 38 monotypic sections in the Old World and 24 monotypic sections in the New World. There are also several local and regional endemites sections in different countries of the world. Majority of the sections contain 10 to 60 species and only a few sections consist of 70 to 120 species.
All sections were arranged according phylogenetical new grouping of A, B, C, D, F, G ,H. Each group contains several sections which show Taxonomic affinities together. All species alphabetically arranged in sections with their synonyms.
