Abstract
A new section of Hemigenia, Hemigenia sect. Malleantha G.R.Guerin sect. nov., is split from the typical section of Hemigenia, as its members do not belong with the type species of the genus (and therefore of the typical section), H. purpurea R.Br. A taxonomic revision of Hemigenia sect. Malleantha is presented which recognises 27 species, including the following 13 new species: H. appressa G.R.Guerin, H. benthamii G.R.Guerin, H. botryphylla G.R.Guerin, H. bracteosa G.R.Guerin, H. buccinata G.R.Guerin, H. ciliata G.R.Guerin, H. dulca G.R.Guerin, H. pachyphylla G.R.Guerin, H. royceana G.R.Guerin, H. tenelliflora G.R.Guerin, H. tomentosa G.R.Guerin, H. virescens G.R.Guerin and H. wandooana G.R.Guerin. Hemigenia parviflora Bartl. is reinstated from synonymy under H. sericea var. parviflora (Bartl.) Benth. Hemigenia eutaxioides C.R.P.Andrews is synonymised with H. teretiuscula F.Muell. and H. sericea var. lanosa F.Muell. ex Benth. is synonymised with H. argentea Bartl.
