New, locally endemic taxa in Leucopogon (Ericaceae: Styphelioideae: Styphelieae) from the Perth and midwest regions of Western Australia

Four new taxa, Leucopogon maritimus Hislop, L. nitidus Hislop, L. stokesii Hislop, and L. squarrosus Benth. subsp. trigynus Hislop are described and mapped; the first three are illustrated. All have very restricted distributions and are of high conservation priority. Lectotypes for L. squarrosus and L. brachycephalus DC. var. heterophyllus Sond. are designated.
