Lepidosperma prospectum G.T.Plunkett & R.L.Barrett (Cyperaceae tribe Schoeneae) is here described as a new species in the Sydney region of New South Wales. It is highly restricted in distribution, occurring at Manly (Sydney Harbour National Park), Kamay Botany Bay National Park and Royal National Park in dense coastal shrublands behind coastal cliffs. These locations are within the traditional lands of the Gamaragal, Gweagal and Dharawal people respectively. Joseph Banks and Daniel Solander were the first Europeans to explore the flora of New South Wales in 1770 around Botany Bay but they did not collect this species. Lepidosperma prospectum is superficially similar to L. sieberi Kunth, which occurs in adjacent habitats, but molecular data have shown that it is more closely allied to Western Australian species. A brief review of recorded indigenous and European knowledge and utilisation of the genus Lepidosperma Labill. is presented to highlight the varied uses of the genus.

The diaspores of Anarthriaceae and Australian Restionaceae are seeds or small nuts and are illustrated by scanning electron microscopy or multifocus microscopy and considered in relation to a previously published phylogeny based on plastid genes. Loculicidal trilocular capsular fruits are the basal condition in the restiid clade, but indehiscent fruits have evolved many times. In the Australasian members, indehiscent fruits are found in Anarthriaceae (Hopkinsia); Restionaceae: Centrolepidoideae (Aphelia); Sporadanthoideae (Calorophus); Leptocarpoideae (Empodisma, Winifredia and the whole of the Leptocarpus and Desmocladus clades). Seeds of dehiscent fruits show a diversity of surface ornamentation with distinctive surface patterns characterising genera such as Lyginia, Chordifex and Loxocarya. Pericarps are membranous in subfam. Centrolepidoideae but in the Leptocarpus clade range from hyaline in much of Leptocarpus to hard and woody in Alexgeorgea and Hypolaena. Pericarps are parenchymatous in most of the Desmocladus clade, but woody in Catacolea. Indehiscent fruits are mostly shed with tepals and floral bracts attached or, in Baloskion and some Lepidobolus species, also with the subtending glume. Seed weights were not comprehensively sampled but vary from 0.08 mg in Centrolepis to >600 mg in Alexgeorgea, with most in the range 0.3–3 mg [dry weight]. The smaller weights are mostly either in perennials of habitats with more reliable rainfall or in ephemeral annuals that avoid drought by their brief growing season, but the association between seed type and habitat has not been investigated. We see no convincing evidence to link to Restionaceae the fossil taxon Restiocarpum and the Milfordia pollen that occurs with it in Eocene–Oligocene sediments of Queensland.

A new species of Utricularia (Lentibulariaceae) is recognised for north-eastern Western Australia. A description of Utricularia baliboongarnang Baleeiro & R.W.Jobson is provided along with a new circumscription for the Northern Territory species U. singeriana F.Muell. to which it was previously assigned. We also provide comparison with U. hamiltonii F.E.Lloyd.; a Northern Territory species for which U. baliboongarnang was recently found to be the phylogenetic sister, and the distantly related western Kimberley species U. byrneana R.W.Jobson & Baleeiro of which it superficially shares a similar corolla. Diagnostic features are illustrated, and distribution, habitat, and conservation status are discussed.

The correct citation for Grevillea manglesii (Proteaceae) is G. manglesii Pépin (1838). A neotype is here selected from among historic collections, now at Paris (P). Should the minimal description provided by Pépin be successfully challenged as inadequate, the name would not change but the revised authority would be Grevillea manglesii (Graham) A.Baumann and N.Baumann (1843). The origins and complex taxonomic and horticultural history of G. manglesii and its synonyms Manglesia glabrata Lindl., Anadenia manglesii Graham, Grevillea manglesii Hort., Manglesia trilobata Hort. ex Ettingsh., and Manglesia cuneata Endl. are outlined and discussed, together with new insights discerned from James Mangles’ unpublished Letter Books. The important role of Captain James Mangles R.N. to the botany and horticulture of Grevillea manglesii is reviewed and historical errors are corrected. Manglesia glabrata Lindl. is lectotypified. G. ornithopoda Meisn. is reinstated at specific rank and G. dissectifolia (McGill.) Olde is published as a new combination. Both are phenetically diagnosable without intergrades and occur in discrete populations that sometimes overlap the distribution of related species.

After a thorough consideration of the history of the European collection and subsequent early cultivation of the commercial flannel flower, a lectotype is designated for Actinotus helianthi Labill. (Umbelliferae/Apiaceae) and the earliest publication (by Trattinnick in 1814) of A. minor (Sm.) Tratt. pinpointed. Other neglected names coined by Trattinnick, including generic ones, applied to Australian and other plants, and published on (generally) plagiarised plates, are discussed and disposed of. One such plate is a copy of the iconotype of Amaryllis × johnsoniana Ker Gawl., an earlier epithet for Hippeastrum × johnsonii (Gowen) Herb. (Amaryllidaceae), a bulbous plant long cultivated in Australia and whose name should be conserved with the later spelling. Attention is drawn to confusions in localities on labels attached to specimens of species (in various families) collected on both D’Entrecasteaux’s and Baudin’s voyages to Australia.

This report of new records for the Philippine and Luzon’s moss flora has once again highlighted the importance of continued bryological studies in the archipelago. In this respect, field collecting in the country’s intervening islands and understudied areas is still necessary to further improve of knowledge of Philippine moss flora.

Prostanthera gilesii is a critically endangered species from the Central Tablelands of New South Wales. A conservation management strategy is currently underway for this species, whose phylogenetic affinities are not known. Morphologically, P. gilesii resembles P. phylicifolia and a population of uncertain identity from Evans Crown Nature Reserve in the Central Tablelands of New South Wales (P. sp. Evans Crown). The taxonomy of P. phylicifolia, however, is unclear. Prostanthera phylicifolia was described from populations in the Victorian Alps and Monaro; however, populations spanning from Victoria to southern Queensland have been variously identified as either P. phylicifolia or P. scutellarioides despite substantial geographic disjunctions and morphological dissimilarity. To examine the relationship between populations identified as P. phylicifolia, P. gilesii and P. sp. Evans Crown, nuclear (external transcribed spacer, ETS) and chloroplast (trnH-psbA intergenic spacer) regions were sequenced and combined with an existing Prostanthera dataset and analysed with maximum-likelihood and Bayesian-inference methods. Prostanthera gilesii and P. sp. Evans Crown were recovered as sister taxa within a clade consisting of populations morphologically similar to the type of P. phylicifolia from the Victorian Alps and Snowy Mountains, Monaro and Southern Tablelands of New South Wales. Populations from northern New South Wales and southern Queensland identified as P. phylicifolia or P. scutellarioides were recovered as an assemblage of unrelated clades. The molecular phylogeny supports P. gilesii and P. phylicifolia as closely related as hypothesised based on morphology and supports P. sp. Evans Crown as a population which requires additional study to assess its taxonomic status.

Grevillea speckiana Olde is described from a single collection gathered in 1953. Although the specimens bears flowers in early bud, fruits and foliage are sufficient to assign and describe the species. Unlike several other species in the Triloba Group awaiting description from single specimens that represent extinct species, there is some hope for its continued existence because of the botanically unexplored locality in which it was collected.
