Redescription of Utricularia singeriana and a new species Utricularia baliboongarnang Baleeiro & R.W.Jobson for north-eastern Western Australia

Abstract

A new species of Utricularia (Lentibulariaceae) is recognised for north-eastern Western Australia. A description of Utricularia baliboongarnang Baleeiro & R.W.Jobson is provided along with a new circumscription for the Northern Territory species U. singeriana F.Muell. to which it was previously assigned. We also provide comparison with U. hamiltonii F.E.Lloyd.; a Northern Territory species for which U. baliboongarnang was recently found to be the phylogenetic sister, and the distantly related western Kimberley species U. byrneana R.W.Jobson & Baleeiro of which it superficially shares a similar corolla. Diagnostic features are illustrated, and distribution, habitat, and conservation status are discussed.
