Two subspecies are here recognised in the geographically rare and taxonomically isolated Eucalyptus insularis Brooker. Eucalyptus insularis subsp. insularis is known only from North Twin Peak Island in the Recherche Archipelago, about 90 km east-south-east of Esperance. Eucalyptus insularis subsp. continentalis D.Nicolle & Brooker subsp. nov. is known only from several small populations near Cape Le Grand on the mainland, about 25 km south-east of Esperance, and differs from the type subspecies in its low shrubby habit, smaller adult leaves with obscure tertiary venation and irregularly-shaped oil glands, more strongly pendulous inflorescences, and its generally smaller buds and fruits. © Department of Parks and Wildlife 2014.

Three taxa are recognised within the previously-accepted concept of E. erythronema Turcz. The taxon previously known as E. erythronema var. marginata (Benth.) Domin is regarded as specifically distinct and is here described as E. armillata D.Nicolle & M.E.French. The taxon previously known as E. erythronema var. erythronema has two variants: a north-eastern variant with conspicuously waxy branchlets and usually red flowers, which we recognise as E. erythronema subsp. erythronema, and a south-western variant with non-waxy branchlets and consistently pale creamy yellow flowers, which we describe as E. erythronema subsp. inornata D.Nicolle & M.E.French. A distribution map for the three taxa previously included in E. erythronema and a key to E. ser. Elongatae Blakely (in which the three taxa treated here are included) are provided. © Department of Environment and Conservation 2012.

Twenty terminal taxa (including 18 species) are recognised in Eucalyptus ser. Falcatae. Brooker & Hopper. We include the monotypic E. ser. Cooperianae L.A.S.Johnson ex Brooker (E. cooperiana F.Muell.) in the series. The new species E. annettae D.Nicolle & M.E.French and E. opimiflora D.Nicolle & M.E.French and the new subspecies E. goniantha Turcz. subsp. kynoura D.Nicolle & M.E.French are described. New combinations made are E. adesmophloia (Brooker & Hopper) D.Nicolle & M.E.French, E. ecostata (Maiden) D.Nicolle & M.E.French and E. notactites (L.A.S.Johnson & K.D.Hill) D.Nicolle & M.E.French. The circumscription of some taxa is significantly modified from previous accounts, including that of E. falcata Turcz., E. goniantha and E. obesa Brooker & Hopper. The name E. dorrienii Domin is resurrected to accommodate populations of mallees previously erroneously called E. falcata. We reject the status of the following previously accepted taxa: E. argyphea L.A.S.Johnson & K.D.Hill (= E. falcata), E. balanites Grayling & Brooker (= E. decipiens × E. lane-poolei), E. balanopelex L.A.S.Johnson & K.D.Hill (= E. semiglobosa × E. kessellii subsp. eugnosta), E. communalis Brooker & Hopper (= E. adesmophloia - E. obesa intergrade), E. decipiens subsp. chalara Brooker & Hopper (= E. decipiens - E. adesmophloia intergrade) and E. phylacis L.A.S.Johnson & K.D.Hill (= E. decipiens × E. virginea). Distribution maps and representative images are provided where appropriate. A key to the taxa of E. ser. Falcatae is provided. © Department of Environment and Conservation 2012.

Nicolle, D. & French, M.E. Two new mallee box species (Eucalyptus sect. Adnataria ser. Lucasianae; Myrtaceae) from the Pilbara region of WesternAustralia. Nuytsia 22(1): 17-29 (2012). Two new species are described, both which have previously been included in E. lucasii Blakely, viz: E.aridimontana D.Nicolle & M.E.French sp. nov., known from high mountain ridges of the Hamersley Range, and E.rowleyi D.Nicolle & M.E.French sp. nov., known from plains of the De Grey River catchment to the north-east of the Hamersley Range. Both species differ from E. lucasii in their adult leaves which age to green and/or glossy, and in their thickened pedicels and peduncles (among other characteristics). Eucalyptus lucasii, as now circumscribed, is a widespread species restricted to watercourses and flood-out plains south of the Pilbara region. A key to E. ser. Lucasianae Chippend. and distribution maps for E. lucasii, E. aridimontana and E. rowleyi are provided. © Department of Environment and Conservation 2012.

A total of 27 phrase names in Corymbia K.D.Hill & L.A.S.Johnson (1) and Eucalyptus L'Hér. (25) which occur at least partly in Western Australia have been assessed with respect to their identity and status. Of these 27 phrase names, we recommend that 14 be removed from Western Australia's plant census because they either represent duplicate names (taxonomically matching another phrase name or published taxon), are taxonomically indistinct or very poorly understood, or are considered to represent hybrids. We erect eight new phrase names for Eucalyptus in Western Australia. © Department of Environment and Conservation 2012.
