<i>Corrigendum to</i>: Morphological and molecular evidence refute a broad circumscription for <i>Pultenaea glabra</i> (Fabaceae: Mirbelieae), with implications for taxonomy, biogeography, and conservation

Abstract

Morphological and single-nucleotide polymorphism data support splitting <i>Pultenaea glabra</i> Benth. into eight species, including one in Victoria, and seven in eastern and northern New South Wales. Six species are newly described, five of which are, like <i>P. glabra</i>, narrow-range endemics within the Greater Blue Mountains World Heritage Area and adjacent sandstone landforms of the Great Dividing Range. The recognition of six new species from what was broadly <i>P. glabra</i> has implications for conservation management, including for <i>P. glabra</i> itself, which has a smaller distribution and more precise habitat requirements than previously thought. One of the new species, <i>P. percussa</i>, is known by a single 1971 gathering only. The occurrence of several narrow-range Blue Mountains endemic <i>Pultenaea</i> species may be explained by the combination of edaphic diversity and topographic complexity, which could act in concert to promote divergences among small, allopatric populations. Hybrids between <i>P. glabra</i> and <i>P. flexilis</i> Sm. are documented for the first time; however, limited evidence for introgression between the two species was observed. The following new taxa are described: <i>Pultenaea aculeata</i> M.A.M.Renner, P.H.Weston & S.Clarke, <i>Pultenaea percussa</i> M.A.M.Renner & P.H.Weston, <i>Pultenaea furcata</i> M.A.M.Renner & R.L.Barrett, <i>Pultenaea mutabilis</i> M.A.M.Renner & P.H.Weston, <i>Pultenaea mutabilis</i> var. <i>angusta</i> M.A.M.Renner, P.H.Weston, & S.Clarke, <i>Pultenaea praecipua</i> M.A.M.Renner & P.H.Weston, <i>Pultenaea praecipua</i> subsp. <i>temperata</i> M.A.M.Renner & R.L.Barrett, and <i>Pultenaea tenebrosa</i> M.A.M.Renner, P.H.Weston & S.Clarke. Lectotypes are designated for <i>Pultenaea villosa</i> var. <i>glabrescens</i> Benth. and <i>Pultenaea weindorferi</i> Reader.
