Ridsdalea

Ridsdalea is an Asian genus of plants in the family Rubiaceae; it was named after Dr. Colin Ernest Ridsdale (1944–2017), who was an English botanist and specialist in tropical plants and the Rubiaceae family.^[3] The type species is Ridsdalea grandis (Korth.) J.T.Pereira, which was renamed from the basionym Gardenia grandis.^[1] Several other species have been reassigned from other genera: notably Rothmannia, which is now reserved for African species. Its native range is southern China, Indo-China, Malesia and New Guinea.
