Shorea is a large genus in family Dipterocarpaceae, and has been subject to substantial revision over the decades. Prior to 2022 the genus included nearly 200 genera.[1]
Based on phylogenomic analyses showing that genus Shorea sensu Ashton (1982) was polyphyletic, in 2022 Ashton and Heckenhauer proposed reviving the former genera Doona Thwaites, Pentacme A.DC., and Richetia F.Heim, raising Shorea sections Anthoshorea and Neohopea to genus rank, and combining Shorea sections Brachyptera, Mutica, Ovalis, Pachycarpae, and Rubella into the new genus Rubroshorea, with two sections, Shorea and Barbata, remaining in genus Shorea.[1] Plants of the World Online currently recognizes Anthoshorea, Doona, Neohopea, Pentacme, Richetia, and Rubroshorea as separate genera.[2]
