Abstract

A taxonomic revision of the Pultenaea setulosa species complex (Fabaceae, tribe Mirbelieae) is presented. Prior to this study, P. setulosa Benth. was broadly circumscribed as a single, morphologically variable species. Here, we present evidence supporting the recognition of 18 species, 14 of which are new to science. Pultenaea setulosa is recircumscribed as a morphologically uniform taxon endemic to the Marlborough region in south-east Queensland. We reinstate Pultenaea boormanii H.B.Will., Pultenaea campbellii Maiden & Betche and Pultenaea lapidosa Corrick from synonymy of P. setulosa and describe an additional 14 new species: Pultenaea acanthocalyx R.L.Barrett & Clugston, Pultenaea corrickiae R.L.Barrett, Orme & Clugston, Pultenaea estelleae R.L.Barrett & Clugston, Pultenaea farmeriana R.L.Barrett, Orme & P.H.Weston, Pultenaea hoskingii R.L.Barrett & Clugston, Pultenaea imminuta R.L.Barrett & S.F.McCune, Pultenaea murrayi R.L.Barrett, Pultenaea palssoniae R.L.Barrett & Clugston, Pultenaea praetermissa R.L.Barrett & Albr., Pultenaea purdieae R.L.Barrett & Clugston, Pultenaea renneri R.L.Barrett & Clugston, Pultenaea venusta R.L.Barrett & Orme, Pultenaea westonii R.L.Barrett & Clugston and Pultenaea woolcockiorum R.L.Barrett & Clugston. Sixteen of these species are endemic to New South Wales, one to Queensland and one to Victoria. All taxa are described and illustrated, and habitats and conservation status are discussed. Two additional related species, Pultenaea procumbens A.Cunn. and P. setigera A.Cunn. ex Benth. are recircumscribed. Pultenaea setigera is reinstated here, known from the type collection made in 1822 and is possibly extinct. Lectotypes are selected for the names Pultenaea boormanii, P. campbellii, P. procumbens, P. setigera and P. setulosa.

Keywords: Australia, legumes, New South Wales, plant taxonomy, Queensland, rare species, short-range endemics, speciation, systematics, Victoria.
