Formal naming of Bossiaea reptans (Fabaceae), an endangered species from the Warren region, Western Australia

Abstract

Recent work on Bossiaea Vent. (Fabaceae) of Western Australia includes a full conspectus by Ross (2006), two further new species by Barrett and Barrett (2015) and a review by Keighery (2018) of the B. eriocarpa Benth. and B. ornata (Lindl.) Benth. group, including the resurrection of two species from synonymy and the description of a new species. Currently there are 42 described species in Western Australia and two phrase-named taxa (Western Australian Herbarium 1998-), of which B. sp. Frankland (E.M. Sandiford EMS 896) was described and illustrated by Ross (2006) but not formally named given the paucity of available material. Further study of this taxon in the field and herbarium has convinced us that it is a distinct species that merits formal description.
