The taxonomic limits of Styphelia (Ericaceae, Epacridoideae, Styphelieae) have been contentious since the genus was first described. At one extreme, it has been circumscribed so broadly as to include most epacrids with drupaceous fruit, at the other, to include only those species that also have long-exserted anthers and styles. Recent molecular phylogenetic analyses have indicated that while all previous circumscriptions of Styphelia are non-monophyletic, a large clade (the Astroloma–Styphelia clade) is consistently well supported. This clade comprises Astroloma, in part (i.e. section Stomarrhena sensu Bentham), Coleanthera, Croninia, Leucopogon, in part (i.e. section Pleuranthus sensu Bentham) and Styphelia sensu Bentham. On the basis of those analyses, we here recircumscribe Styphelia phylogenetically to include all species belonging to the Styphelia–Astroloma clade. The 146 taxa occur mostly in Australia, with smaller numbers in New Zealand, New Caledonia (1 species extends to Fiji and Vanuatu) and Malesia. An additional 74 phrase-named taxa belong to this clade, including 70 from Western Australia and 4 from eastern Australia (all other Australian states and territories). The Styphelia floras of Western Australia, eastern Australia, New Caledonia and Malesia are each endemic or nearly so; 1 species (S. nesophila (DC.) Sleumer) is shared between New Zealand and eastern Australia, and 2 species (S. cordifolia (Lindl.) F.Muell. and S. woodsii (F.Muell.) F.Muell.) are shared between Western Australia and eastern Australia. An amended diagnosis of Styphelia is provided, new combinations are made for 25 taxa, and new names published for another 9. Lectotypes are designated for two names (Leucopogon brevicuspis Benth. and L. strictus Benth.) found to have taxonomically heterogeneous syntypes.

Specific Rank

It is reported that Gaudichaud was correct in describing, under Brachycome Cass., three species, B. triloba, B. dentata and B. spathulata. Reference is made to the nomenclatural status of these species in accordance with the results of a revision of Brachycome by Davis (1948). De Candolle erred in transferring the species to Vittadinia A. Rich, for which the New Zealand V. australis is the type. Reasons are given for regarding V. triloba (Gaudich.) DC. as synonymous with V. australis var. dissecta Benth., and the variety is raised to specific rank. Included with V. australis and V. dissecta in Vittadinia s. str. (i.e. in Vittadinia subgenus Vittadinia) are V. cuneata DC. (a name which can be applied to a complex group of taxa widespread in southern and eastern Australia) and a further 17 species of which the following are new: V. cervicularis (with four varieties), V. constricta, V. condyloides, V. decora, V. eremaea, V. humerata, V. nullarborensis, V. pustulata, V. simulans and V. sulcata, while V. gracilis (J. D. Hook.) N. Burbidge and V. australasica (Turcz.) N. Burbidge are new combinations. V. scabra DC. and a group of taxa which have been referred to it or, incorrectly, to V. macrorhiza (DC.) A. Gray have been placed in a new subgenus of Vittadinia under the name Peripleura. Within this subgenus nine species are recognized: V. scabra DC., V, hispidula F. Muell. ex A. Gray (with two varieties), and the new species V. arida, V. bicolor, V. diffusa, V. obovata, V. sericea, V. spechtii (with two varieties) and V. virgata. With the exception of V. australis which is endemic to New Zealand and V. simulans, a New Caledonian species, all are endemic to Australia; however, V. hispidula has been reported for New Caledonia where it is deemed to be an alien and V. gracilis and possibly V. muelleri appear to have become naturalized in New Zealand. V. brachycomoides (F. Muell.) Benth. becomes the type of a new genus, Camptacra, with two species, both distributed in northern and north-eastern Australia. Eurybiopsis DC. is reinstated, with its single species, E. macrorhiza DC., found only in northern Australia.

AbstractThe lithobiomorph centipede Henicops is widely distributed in Australia and New Zealand, with five described species, as well as two species in New Caledonia and Lord Howe Island. Parsimony, maximum likelihood and Bayesian analyses of ca. 800 aligned bases of sequence data from 16S rRNA and 28S rRNA were conducted on a dataset including multiple individuals of Henicops species from populations sampled from different parts of species' geographic ranges, together with the allied henicopines Lamyctes and Easonobius. Morphological characters are included in parsimony analyses. Molecular and combined datasets unite species from eastern Australia and New Zealand to the exclusion of species from Western Australia, New Caledonia and Lord Howe Island. The molecular data favour these two geographic groupings as clades, whereas inclusion of morphology resolves New Caledonia, Lord Howe Island, southwest Western Australia and Queensland as successive sisters to southeastern Australia and New Zealand. The basal position of the Lord Howe Island species in the phylogeny favours a diversification of Australasian Henicops since the late Miocene unless the Lord Howe species originated in a biota that pre-dates the island. The molecular and combined data resolve the widespread morphospecies H. maculatus as paraphyletic, with its populations contributing to the geographic groupings New South Wales + New Zealand and Tasmania + Victoria.

As currently circumscribed, Boronia (Rutaceae) is a large Australian genus of 148 species distributed in all states and mainland territories, and Boronella is confined to New Caledonia and contains ~four species. We present molecular phylogenetic analyses of these genera, based on chloroplast (trnL–trnF) and nuclear (ITS, ETS) DNA sequences, to assess their relationships and infrageneric classification. Analyses strongly support the monophyly of a Boronia+Boronella clade and that Boronella is nested within Boronia. They also support the monophyly of Boronella and Boronia sections Algidae, Valvatae and Cyanothamnus, and ser. Pedunculatae (sect. Boronia), but resolve sect. Boronia and ser. Boronia as polyphyletic. On the basis of these results, we propose a new classification wherein Boronella is transferred to Boronia and recognised at the rank of section, and a new name and two new combinations in Boronia are provided for the following three species: Boronia hartleyi Duretto & Bayly, Boronia pancheri (Baill.) Duretto & Bayly and Boronia parvifolia (Baker f.) Duretto & Bayly. A revised circumscription is presented for Boronia sect. Boronia, and Pedunculatae is elevated from a series to a section. The relationships and classification of some taxa require further clarification, either because of limited taxon sampling, or because some nodes in phylogenetic analyses are poorly resolved or supported.

We re-examined the taxonomic status of plants treated as Sedum formosanum (Crassulaceae) from Miyako-jima Island of the Ryukyu Islands, Japan, using morphological comparison and molecular phylogenetic analyses with related species. In morphology, plants from Miyako-jima Island bore a close resemblance to the other plants of S. formosanum, but differed in being perennial, polycarpic, and having lateral axillary branches. Molecular analyses based on ITS of nrDNA and six regions of cpDNA sequencing indicated that the Miyako-jima plants formed a distinct subclade. This subclade was part of a polytomy with three other subclades comprising nine taxa endemic to Taiwan and S. formosanum from other areas, including the type locality. Therefore, we propose and describe the Miyako-jima plants as a new subspecies, Sedum formosanum subsp. miyakojimense.

Eucalypt Forests

Abstract U. lugens was first considered a serious pest of natural eucalypt forests in Western Australia in 1983 when the first severe outbreak occurred there (Strelein, 1988). Prior to that it was widely known as a pest of eucalypt forests in eastern Australia (Campbell, 1962; Harris, 1974). As these natural forests are or were managed for timber production, it is considered an economically important pest in its native range. Damage to amenity trees is also a common problem, although few trees are killed by this defoliation (Anonymous, 1979).U. lugens was recorded as invasive in New Zealand by Crabtree (1997). In its exotic range it has become a significant pest of amenity trees, particularly Lophestemon confertus (Australian brush box), which is commonly planted in some parts of Auckland City (Kriticos et al., 2007).

The 19 Indo-Pacific species of the snake-eel genus Ophichthus (family Ophichthidae, subfamily Ophichthinae) that live at or below 200 m are reviewed. Included are: Ophichthus aphotistos, O. brachynotopterus, O. echeloides, O. exourus, O. genie, O. kunaloa, O. megalops, O. mystacinus, O. serpentinus, O. urolophus, and nine new species which are described: O. alleni from 115–200 m off eastern Australia; O. aniptocheilos from 391–421 m off Tonga; O. congroides from 300 m off the Tuamotu Islands; O. hirritus from 600 m off the Seychelle Islands; O. humanni from 254–300 m off Vanuatu; O. ishiyamorum from 258–400 m off the Gulf of Aden, Somalia; O. lentiginosus from 400 m off Vanuatu and New Caledonia; O. microstictus from 362–450 m off Tonga, Fiji, and possibly New Caledonia; and O. tomioi from 300– 423 m off the Philippines, Marquesas, Fiji, and the Seychelle Islands. The range and depth distributions of the following are expanded to include: O. brachynotopterus to New Caledonia and Vanuatu between 541–580 m; O. mystacinus to Tonga, Fiji, and the Philippines between 371–824 m; and O. urolophus to Western Australia and Indonesia between 40– 420 m. An identification key is provided. Characteristics and the behavior of species of the subgenus Coecilophis, to which all treated species except O. aphotistos belong, is discussed. Ophichthys madagascariensis Fourmanoir (1961) is proposed to be a junior synonym of Pisodonophis cancrivorus (Richardson 1848).

Gene Sequence Data

Coloration, gene-sequence data (H3, 12s, 16s), and subtle features in morphology support the description of two new species, both formerly regarded to represent accepted variants of Phimochirus holthuisi s.l. While color in life consistently separates these species from P. holthuisi s.s. and from each other, morphological distinctions are subtle and less than absolute in small specimens, being based on ventral spine counts of walking leg dactyls and relative development of the superior crest on the major chela. Molecular phylogenetic analyses clearly support the separation of sister clades, representing two new species, from P. holthuisi s.s. as well as other congeners available for analysis. Both of the new species are presently known to occur widely throughout the northern Gulf of Mexico, though one occurs more commonly in the northeastern and southeastern Gulf, and may range as far south as Suriname. The other has been taken primarily in the northwestern Gulf, and is not known from outside Gulf waters. While both of the new species appear restricted to relatively deep subtidal waters of the continental shelf, Phimochirus holthuisi s.s. is instead more commonly found in shallow nearshore tropical waters on or near coral reefs. Previous literature reports of P. holthuisi usually represent, at least in part, one or both of these two new species.

A New Species

A new species of Afroboletus, namely A. sequestratus, is described from Zambia. Evidence from molecular phylogenetic analyses using sequences rpb1, rpb2 and tef1α and morphological comparison support its placement in Afroboletus and it is distinct from the other related members of this genus in Africa. It is the first species with sequestrate basidiomata in the genus. A morphological description is augmented with line drawings and SEM images for the species.

Cortinarius section Xenosmatae, originally based on solely morphological characters, was subsequently shown to contain phylogenetically distantly related species. The type species C. xenosma is a singleton, and this study aims to revise the other members of the section using combined molecular (nrDNA ITS and LSU) and morphological data. Based on phylogenetic analyses using RAxML, PhyML and Bayesian Inference and additional morphological features one new species (C. paraxenosma) and one new section (sect. Olorinati) are proposed. Furthermore sect. Carbonelli is extended and emended to include two former members of sect. Xenosmatae. A key to the species in New Zealand with xenosmatoid morphology is provided.

In the Australia–Pacific Region ultramafic outcrops are both widespread and extensive, covering thousands of km2. Soils derived from ultramafic bedrock impose edaphic challenges and are widely known to host highly distinctive floras with high levels of endemism. In the Australia–Pacific Region, the ultramafics of the island of New Caledonia are famed for harbouring 2150 species of vascular plants of which 83% are endemic. Although the ultramafic outcrops in Western Australia are also extensive and harbour 1355 taxa, only 14 species are known to be endemic or have distributions centred on ultramafics. The ultramafic outcrops in New Zealand and Tasmania are small and relatively species-poor. The ultramafic outcrops in Queensland are much larger and host 553 species of which 18 (or possibly 21) species are endemic. Although New Caledonia has a high concentration of Ni hyperaccumulator species (65), only one species from Western Australia and two species from Queensland have so far been found. No Ni hyperaccumulator species are known from Tasmania and New Zealand. Habitat destruction due to forest clearing, uncontrolled fires and nickel mining in New Caledonia impacts on the plant species restricted to ultramafic soils there. In comparison with the nearby floras of New Guinea and South-east Asia, the flora of the Australia–Pacific Region is relatively well studied through the collection of a large number of herbarium specimens. However, there is a need for studies on the evolution of plant lineages on ultramafic soils especially regarding their distinctive morphological characteristics and in relation to hyperaccumulation.
