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.

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.

Complex Relationships

Background and aims – Molecular phylogenetic studies have provided a clearer understanding of the complex relationships within the family Cyperaceae. These studies have consistently shown that 12 allied genera are nested in the genus Cyperus. However, early Sanger sequencing-based phylogenies that included the two species of the small South American genus Androtrichum were inconclusive in placing this genus either as sister to Cyperus or as part of its early divergent lineages. A recent phylogenetic analysis however conclusively placed the two species of Androtrichum within the C3 Cyperus Grade. In this study, we investigate if the morphology and anatomy of Androtrichum species provide additional evidence for their placement in the genus Cyperus. In addition, we provide descriptions and distribution data for the species.Material and methods – Herbarium material from FLOR, FURB, GENT, ICN, and K has been studied. Samples of the culm and leaf were studied using histological methods. Taxonomic changes and typifications of names were performed according to the International Code of Nomenclature for algae, fungi, and plants. Key results – The morphology and the non-Kranz anatomy observed in the Androtrichum species confirm their placement among the other C3  Cyperus species. Androtrichum is combined into Cyperus. For one species, a combination in Cyperus is already available: Cyperus trigynus. For the other species, a new name in Cyperus is published: Cyperus byssaceus. Two typifications are established and morphological descriptions and distribution data are provided. Conclusion – By integrating recent molecular phylogenetic data with additional evidence from morphology and anatomy, Androtrichum is combined into Cyperus. As a result of this taxonomic change, a single monophyletic genus Cyperus is now recognised in the Cyperus Clade of tribe Cypereae.

Typically, females of eriophyoid mites of the large conifer-associated genus Trisetacus Keifer 1952 have long spermathecal tubes, which are at least twice as long as the spermathecae. In this paper, we report on four Trisetacus species collected in the USA from Cupressaceae that possess atypical short spermathecal tubes and demonstrate a distinct reduction trend in leg chaetotaxy when setae lʹ and/or bv II may be absent, and setae ftʹ II are very short. They are: 1) Trisetacus virginianus n. sp. and 2) T. thujae (Garman 1883, = T. thujivagrans Smith 1977a syn. nov.) from indigenous North American conifers Juniperus virginianus and Thuja occidentalis, respectively, and 3) Trisetacus maculatus n. sp. and 4) T. morgantownensis n. sp. from Japanese endemics, Chamaecyparis pisifera and C. obtusa, respectively, introduced to the USA. In these four Trisetacus species, the spermathecal apparatus consists of two drop-shaped segments, each about 2.5‒3 µm long and about 2‒2.5 µm wide, and resembles that of Boczekella, a nalepellid genus restricted to pinacean genera Larix and Pseudolarix. A new subgenus, Brevithecus n. subgen., is erected within the genus Trisetacus to accommodate the four Trisetacus species from Cupressaceae. Future molecular phylogenetic studies are needed to test whether Brevithecus is nested within Trisetacus or represents a separate genus, which may be a sister to either Trisetacus or Boczekella.

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.

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.

Background – During the past decade several molecular phylogenetic studies tackled the complex relationships within tribe Cypereae. Based on these studies, previously accepted segregate genera such as Pycreus were sunk into the genus Cyperus. Recently, while revising the West African species of Cyperus, three taxa previously placed in Pycreus were identified for which a name in Cyperus is lacking.Methods – The taxonomic changes are performed according to the International Code of Nomenclature for algae, fungi, and plants.Results – Three new combinations in Cyperus are made for names currently placed in Pycreus.

Anatomical Characters

The pantropical family Eriocaulaceae includes ten genera and c. 1,400 species, with diversity concentrated in the New World. The last complete revision of the family was published more than 100 years ago, and until recently the generic and infrageneric relationships were poorly resolved. However, a multi-disciplinary approach over the last 30 years, using morphological and anatomical characters, has been supplemented with additional data from palynology, chemistry, embryology, population genetics, cytology and, more recently, molecular phylogenetic studies. This led to a reassessment of phylogenetic relationships within the family. In this paper we present new data for the ITS and trnL-F regions, analysed separately and in combination, using maximum parsimony and Bayesian inference. The data confirm previous results, and show that many characters traditionally used for differentiating and circumscribing the genera within the family are homoplasious. A new generic key with characters from various sources and reflecting the current taxonomic changes is presented.

Morphological Investigations

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.

Taxonomic Novelties

Recent molecular phylogenetic studies in Chrysobalanaceae as well as new analyses presented in this study cast doubt on the monophyly of the three largest genera in the family, Couepia, Hirtella and Licania. Couepia, a Neotropical genus, had species appearing in four separate clades, the majority of species sequenced, however, form a highly supported clade, referred to here as core Couepia (including the type species). These results lend support to a revised taxonomy of the genus, and to resolve Couepia as monophyletic the following taxonomic changes are here proposed: Couepia recurva should be transferred to Hirtella, C. platycalyx transferred to Licania, C. longipendula and C. dolichopoda transferred to Acioa, and a new genus, Gaulettia, is proposed to accommodate species of the Gaulettia clade and allies.
