The genus Opuntia is one of the most emblematic of the cactus family (Cactaceae) and a species-rich clade within subfamily Opuntioideae. After molecular phylogenetic studies showed that the traditional broad circumscription of Opuntia could not be retained as the genus was polyphyletic, various segregated genera were recognize based on both morphological data and phylogenetic studies. Here, we reassessed an old and enigmatic taxon, O. schickendantzii, through molecular and morphological investigations. Our results support that O. schickendantzii was best circumscribed within the Salmonopuntia lineage based on molecular and morphological features. As a consequence, a new combination is proposed, and an epitype from the herbarium BAF is designated. An updated description of the taxon with illustrations is also given.

Following recent molecular phylogenetic studies in Old World Gesneriaceae the nomenclatural implications for names in Henckelia are examined. New combinations are made in Codonoboea and Loxocarpus to account for species now excluded from Henckelia. A list is presented in which the current position of all species hitherto assigned to Henckelia is given, including the new combination Henckelia rotundata (Barnett) D.J.Middleton & Mich.Möller. A new combination in Oreocharis is made.

Following recent molecular phylogenetic studies, the genus Sphaeromeria has been synonymized with Artemisia and its taxa are included in Artemisia subg. Tridentatae. The new combination is proposed, Artemisia nuttallii (Torr. & A. Gray) Mosyakin, L.M. Shultz & G.V. Boiko, comb. nov. (= Sphaeromeria argentea Nutt., non A. argentea L’Her.; Tanacetum nuttallii Torr. & A. Gray; Artemisia macarthuri Sòn. Garcia et al., nom. illeg.). Notes on typifications of the names Sphaeromeria argentea and S. capitata Nutt. (now Artemisia capitata (Nutt.) Sòn. Garcia et al.) are provided; both are typified by Nuttall’s specimens from BM. Additional original specimens of these two species recently found in the Turczaninow memorial collection at the National Herbarium of Ukraine (KW) are discussed.

A taxonomic synopsis of the members of the re-circumscibed Thyrsacanthus from Argentina and Paraguay is presented. Two species are recognized for the region, T. boliviensis and T. sulcatus. The latter is a new combination here proposed, based on Jacobinia sulcata (until now treated in Carlowrightia), that is corroborated by morphological data and geographic distribution as well as molecular phylogenetic information. Thyrsacanthus sulcatus is clearly distinguished from T. boliviensis by its small, white, lilac or pale blue, presumably psychophilous flowers with a narrow tube, instead of the large and red ornithophilous flowers with a tube that widens to the throat, which is typical of other species of Thyrsacanthus. Differences between the re-circumscribed Thyrsacanthus and other genera of the Tetramerium lineage to which it belongs are discussed, and references to additional genera of Acanthaceae that present similar wide diversification in floral morphology are noted. The synopsis includes a key, full synonymies, descriptions, illustrations, distributions, and lists of representative specimens. Lectotypifications are provided for the following names: Anisacanthus malmei, Dianthera sulcata, Jacobinia caducifolia, Schaueria caduciflora, and Siphonoglossa gentianifolia.

Molecular Phylogenetic Data

The snow hebes, formerly comprising the genus Chionohebe, are here included within Veronica (Plantaginaceae). The five species (including two subspecies) of snow hebes recognised here are cushions or subshrubs that occur exclusively in high-elevation habitats of Australia and the South Island of New Zealand. Species delimitation among the cushion snow hebes is very difficult because of the reduced pulvinate habit, solitary flowers and few gross-morphological characters useful for identification. To address species limits, investigate intraspecific patterns and revise the taxonomy of the snow hebes, morphological analyses were conducted and the results compared with previously published molecular phylogenetic data. Ordination and clustering analyses of morphological data showed some taxonomic structuring; however, species clusters were not widely separated from one another. Morphological and amplified fragment length polymorphism (AFLP) data show that the cushion species are clearly distinguished from the subshrub species, V. densifolia (F.Muell.) F.Muell. Among the four cushion species (V. chionohebe Garn.-Jones, V. ciliolata (Hook.f.) Cheeseman, V. pulvinaris (Hook.f.) Cheeseman, V. thomsonii (Buchanan) Cheeseman), the distribution of leaf trichomes is important for species identification, particularly when used in conjunction with ovary vestiture, capsule size, and/or seed size. One new combination V. ciliolata subsp. fiordensis (Ashwin) Meudt is proposed, and V. uniflora Kirk is treated as a naturally occurring hybrid V. × uniflora (V. densifolia × V. thomsonii). Complete synonymies, descriptions, illustrations and range maps are provided for each species, as well as a key to all species and a discussion of putative hybrids.

Abstract Chascolytrum, as currently circumscribed, includes 22–23 South American species that were previously included in nine different genera (Chascolytrum, Briza, Poidium, Calotheca, Microbriza, Gymnachne, Rhombolytrum, Lombardochloa and Erianthecium). Due to the remarkable morphological diversity, the relationships in Chascolytrum s.l. have remained poorly understood, and no infrageneric classification could be proposed based on the latest molecular phylogenetic studies. In this study, we combined molecular (GBSSI, trnL-trnL-trnF and rps16 intron) and morphological characters to investigate the phylogenetic relationships in Chascolytrum s.l. Based on this, morphologically diagnosable clades were recognized as eight sections (Calotheca, Chascolytrum, Hildaea, Lombardochloa, Microbriza, Obovatae, Poidium and Tricholemma), of which three are new and three are monospecific. We describe each section and discuss the new infrageneric classification in comparison with the previous infrageneric classification proposed for the group under the genus Briza. A taxonomic key and images for most of the species in each section are provided. Last, the use of single-copy nuclear genes and morphological data for future phylogenetic reconstructions encompassing Chascolytrum is highlighted.

The Many

Despite decades of phylogenetic studies, the generic and species-level relationships of some Australian elapid snakes remain problematic. The morphologically conservative genus Parasuta comprises small nocturnal snakes with a particularly obfuscated taxonomic history. Here we provide a molecular phylogenetic analysis of all currently recognised species including members of the sister genus Suta and provide new morphological data that lead to a taxonomic revision of generic and species boundaries. We failed to find support for monophyly of Parasuta or Suta, instead supporting previous evidence that these two genera should be combined. Our species-level investigations revise the boundaries between P. gouldii (Gray) and P. spectabilis (Krefft) resulting in recognition that both P. spectabilis bushi (Storr) and P. spectabilis nullarbor (Storr) are conspecific with P. gouldii. We also find the Pilbara population of P. monachus (Storr) to be specifically distinct. As a consequence of this information, we synonymise Parasuta with its senior synonym Suta, redescribe S. gouldii, S. monachus and S. spectabilis to clarify morphological and geographical boundaries and describe S. gaikhorstorum sp. nov., which differs from all other described Suta species, including the geographically proximate and similar-looking S. monachus, by a combination of molecular genetic markers, morphometric attributes, details of colouration and scalation. The recognition of S. gaikhorstorum sp. nov. adds to the growing list of the many endemic reptiles from this exceptionally diverse biotic region. We also designate a lectotype for S. spectabilis from the original syntype series, highlight a distinctive population from the Great Victoria Desert in Western Australia and comment on further unresolved issues regarding the relationships between S. dwyeri (Worrell) and S. nigriceps (Gȕnther).

Taxonomic Changes

Molecular phylogenetic studies of complex thalloid liverworts have resolved relationships that require taxonomic and nomenclatural changes. Since Bucegia and Preissia are deeply nested within Marchantia, species formerly placed in these genera are transferred to Marchantia as Marchantia romanica, comb. nov. and Marchantia quadrata, respectively, and placed in the new subgenus, Marchantia subg. Preissia, comb. et stat. nov. The families Exormothecaceae and Corsiniaceae are merged under the earlier name Corsiniaceae. The genus Stephensoniella Kashyap becomes a synonym of Exormotheca and its sole species S. brevipedunculata is transferred to Exormotheca, with the new combination Exormotheca brevipedunculata. In the Cleveaceae, the recent recognition of Clevea as distinct from Athalamia, necessitates the new combination Clevea nana to replace the name Clevea hyalina on the basis of nomenclatural priority.

The Creation

Recent molecular phylogenetic studies (Egan et al., in prep.) have demonstrated widespread polyphyly within the genus Pueraria. A new classification is presented here that delineates monophyletic groups previously considered congeneric with Pueraria. This taxonomic treatment provides several new species combinations and a more natural circumscription of Pueraria by reinstating the genus Neustanthus, transferring one species to Teyleria and establishing two new genera: Haymondia and Toxicopueraria.

Twenty-two non-lichenicolous species of Tremella are reported from Russia. Detailed descriptions, photographs, illustrations and a dichotomous key for the identification of taxa are provided. Two species, Tremella subalpina and T. griseola, are described as new. One new combination is proposed, and an epitype for Tremella yokohamensis is designated. Molecular phylogenetic reconstructions are presented based on nrITS and nrLSU regions in Bayesian and likelihood analyses. Phylogenetic data were strongly correlated with morphological data and were useful to delimit closely related species.

Conniella apterygia is redescribed from re-examination of the holotype, two paratypes, and six additional specimens. The genus is closely allied to Cirrhilabrus, sharing similarities in general morphological and meristic details, but is separated from Cirrhilabrus and most other labrid fishes in lacking pelvic fins and a pelvic girdle. Recent molecular phylogenetic studies have provided strong evidence for the deep nesting of Conniella within Cirrhilabrus, contradicting its generic validity and suggesting that the loss of pelvic elements is autapomorphic. Consequently, the species is redescribed and assigned to the genus Cirrhilabrus, as Cirrhilabrus apterygia new combination. The pelvic morphologies of related cirrhilabrin labrids are discussed, and a new synapomorphy is identified for Paracheilinus.
