“…At Bilpin, Mountain Lagoon and Mooney Mooney Creek, A. keithi occurs on P. flexilis , which is not of conservation concern. Pultenaea flexilis is broadly distributed throughout the coast and Great Dividing Range of New South Wales and into Queensland (de Kok & West 2002), so the distribution of A. keithi may extend even beyond our sampling area. Our records demonstrate that A. keithi is not at risk of coextinction, although local extinction of the A. keithi population at Cataract Falls remains a possibility, particularly if no Pultenaea hosts other than P. glabra are present.…”

Acizzia keithi was described as a monophagous species from the threatened plant Pultenaea glabra at a single, localised site and was therefore believed to be at risk of coextinction. However, following more sampling at sites outside of the known localities of P. glabra, the distribution and host range of A. keithi are expanded to include a congeneric common plant, Pultenaea flexilis. Pultenaea flexilis is broadly distributed throughout the coast and Great Dividing Range of New South Wales and into Queensland. Hence, even though A. keithi was rarely collected in this study, and remains at risk of local extinction on P. glabra at Cataract Falls, it is no longer considered to be a species at risk of coextinction.

“…The genus Pultenaea belongs to the tribe Mirbelieae (Pohill, 1981) in the Fabaceae. The taxonomy of the 91 eastern species in the genus has recently been revised (de Kok & West, 2002. In the following the word 'Pultenaea' will refer only to the endemic eastern Australian species of that genus plus P. tenuifolia.…”

Aim The aim of this research is to develop and investigate methods for the spatial analysis of diversity based on genetic and taxonomic units of difference. We use monophyletic groups of species to assess the potential for these diversity indices to elucidate the geographical components of macro-scaled evolutionary processes. LocationThe range occupied by Pultenaea species in temperate and sub-tropical eastern Australia, extending from western South Australia (133°E-32°S) to Tasmania (146°E-43°S) to coastal central Queensland (148°E-20°S).Methods We applied a series of both spatially explicit and spatially implicit analyses to explore the nature of diversity patterns in the genus Pultenaea, Fabaceae. We first analysed the eastern species as a whole and then the phylogenetic groups within them. We delineated patterns of endemism and biotic (taxon) regions that have been traditionally circumscribed in biogeographical studies of taxa. Centres of endemism were calculated using corrected weighted endemism at a range of spatial scales. Biotic regions were defined by comparing the similarity of species assemblages of grid cells using the Jaccard index and clustering similar cells using hierarchical clustering. On the basis that genetically coherent areas were likely to be more evolutionary informative than species patterns, genetic indices of similarity and difference were derived. A matrix of similarity distances between taxa was generated based on the number of shared informative characters of two sections of trnL-F and ndhF chloroplast nuclear regions. To identify genetically similar areas, we clustered cells using the mean genetic similarities of the species contained within each pair of cells. Measures of the mean genetic similarity of species in areas were delineated using a geographically local multi-scalar approach. Resultant patterns of genetic diversity are interpreted in relation to theories of the evolutionary relationships between species and species groups.

“…The taxonomy of Pultenaea in eastern Australia was revised in three papers by de Kok and West (2002West ( , 2003West ( , 2004, each paper treating a different informal group circumscribed by whether the ovary was glabrous or hairy, and for the latter whether the leaves were involute, or revolute. Glabrous ovaries included those having hairs around the ovary apex only, this qualification was important because a few species have a completely glabrous ovary, or have ovaries with a tuft of hairs at the apex, including P. alea de Kok, P. altissima F.Muell.…”

Morphological and single-nucleotide polymorphism data support splitting Pultenaea glabra 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 P. glabra, 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 P. glabra has implications for conservation management, including for P. glabra itself, which has a smaller distribution and more precise habitat requirements than previously thought. One of the new species, P. percussa, is known by a single 1971 gathering only. The occurrence of several narrow-range Blue Mountains endemic Pultenaea 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 P. glabra and P. flexilis Sm. are documented for the first time; however, limited evidence for introgression between the two species was observed. The following new taxa are described: Pultenaea aculeata M.A.M.Renner, P.H.Weston & S.Clarke, Pultenaea percussa M.A.M.Renner & P.H.Weston, Pultenaea furcata M.A.M.Renner & R.L.Barrett, Pultenaea mutabilis M.A.M.Renner & P.H.Weston, Pultenaea mutabilis var. angusta M.A.M.Renner, P.H.Weston, & S.Clarke, Pultenaea praecipua M.A.M.Renner & P.H.Weston, Pultenaea praecipua subsp. temperata M.A.M.Renner & R.L.Barrett, and Pultenaea tenebrosa M.A.M.Renner, P.H.Weston & S.Clarke. Lectotypes are designated for Pultenaea villosa var. glabrescens Benth. and Pultenaea weindorferi Reader.
