Rytigynia
''Rytigynia'' is a genus of flowering plants in the Rubiaceae family. It is found in tropical and southern Africa. The genera ''Rytigynia'' and ''Fadogia'' form a strongly supported clade but neither of these genera is monophyletic. ==Distribution== ''Rytigynia'' is found in Tropical Africa. ''R. senegalensis'' and ''R. umbellulata'' are the two most widespread species and they are found from Senegal to Sudan to Botswana. ''R. celastroides'' has the southernmost distribution and occurs as far south as KwaZulu-Natal. However, most species are more restricted in distribution area and they are often found in either West or East Africa. Half of the species is even endemic to one country. One-third of all ''Rytigynia'' species is found in Tanzania, and many of them are endemics.〔(【引用サイトリンク】title=''Rytigynia'' in the World Checklist of Rubiaceae )〕
