The troubled taxonomic history of Stylidium graminifolium Sw. ex Willd. (syn. Candollea serrulata Labill.) is reviewed. The entity formerly known as S. graminifolium forms a complex consisting of three species. Stylidium graminifolium sens. str. is lectotypified on the basis of plants collected by Banks and Solander from Botany Bay NSW in 1770. This narrow-linear-leaved species is diploid (2n = 30) and is distributed widely on infertile soils in south-eastern continental Australia and Tasmania. Stylidium armeria Labill., on the basis of plants collected from southern Tasmania in the late 1790s, is a tetraploid (2n = 60), with leaves about two to three or four times wider than in S. graminifolium and more spathulate in shape. It has a strictly littoral habitat along the rough water coasts of Tasmania from Macquarie Heads to Tasman Peninsula, probably extending to the coasts of south-eastern Australia. Stylidium melastachys R.Br., on the basis of plants collected from the Kent Group in Bass Strait in 1803, is synonymous with S. armeria. A third species, S. dilatatum W.D.Jackson and R.J.E.Wiltshire, is described as new. It is morphologically similar to S. graminifolium but has linear leaves about two to three times as wide as S. graminifolium and is a tetraploid (2n = 60). It is widely distributed in Tasmania and in the cooler subalpine areas of south-eastern Australia but is confined to more fertile soils than the soils in which S. graminifolium is found.

The family Prototroctidae, the genus Prototroctes, and the two contained species-P. oxyrhynchus Gunther, 1870 (New Zealand) and P. maraena Gunther 1864 (south-eastern Australia and Tasmania) are described. P. oxyvhynchus is distinguished from P. maraena by much higher counts of lateral scale rows, vertebrae and gill rakers. What is known of the natural history of Prototroctes is reviewed. P. oxyvhynchus is extinct and P. maraena now rare; reasons for the decline of these species are discussed.

AbstractThe speckled warbler and other woodland birds of south-eastern Australia have declined dramatically since European settlement; many species are at risk of becoming locally and/or nationally extinct. Coincidently, Australian environmental education research of the last decade has largely been silent on the development of pedagogy that refects the natural history of this continent (Stewart, 2006). The current circumstances that face the speckled warbler, I argue, is emblematic of both the state of woodland birds of south-eastern Australia, and the condition of natural history pedagogy within Australian environmental education research. In this paper I employ Deleuze and Guattari's (1987) philosophy “becoming-animal” to explore ways that the life and circumstances of the speckled warbler might inform natural history focused Australian environmental education research. The epistemology and ontology ofbecoming-speckled warbleroffers a basis to reconsider and strengthen links between Australian natural history pedagogy and notions of sustainability.

There is considerable uncertainty that the traditional identification of bent grasses in south-eastern Australia as Agrostis capillaris L. (Syn. Agrostis tenuis Sibth.) is correct, due to a history of confusing nomenclature and mis-identification. Bent grass is considered a weed of pastures in the high-rainfall zone of south-eastern Australia and thus the correct identity of bent grass may have implications for its management and control. Populations of bent grass were sampled from 42 pastures in south-eastern Australia and Agrostis castellana Boiss. et Reuter, rather than A. capillaris, was found to be the dominant species of Agrostis in 33 out of 42 bent grass pastures sampled. Five of the nine pastures sampled in Tasmania contained A. capillaris as opposed to only 1 of the 33 pastures sampled in Victoria. Agrostis castellana had not been identified in Victoria or Tasmania prior to this work. Since A. castellana grows more vigorously by rhizomes than A. capillaris, control measures recommended for A. capillaris may not be relevant for bent grass pastures in south-eastern Australia. Ligule length, ligule width and width of lamina, measured to determine whether species of bent grass could be easily distinguished in the field, did not distinguish adequately between A. castellana and A. capillaris.
