“…Group 4 included some Australian taxa commonly recognized in Lachnagrostis (e.g., Widén 1971, Jacobs 2001), two Mediterranean annuals, including A. truncatula Parl., recently recognized as Neoschischkinia truncatula (Parl.) Valdés & H. Scholz (Valdés and Scholz 2006), and a few other species. Widén (1971) refined this classification and recognized seven types of epidermal surface structure, but maintained the traditional classification of the genus, placing species in Agrostis sects.…”

Circumscriptions of and relationships among many genera and suprageneric taxa of the diverse grass tribe Poeae remain controversial. In an attempt to clarify these, we conducted phylogenetic analyses of >2400 new DNA sequences from two nuclear ribosomal regions (ITS, including internal transcribed spacers 1 and 2 and the 5.8S gene, and the 3’-end of the external transcribed spacer (ETS)) and five plastid regions (matK, trnL–trnF, atpF–atpH, psbK–psbI, psbA–rps19–trnH), and of more than 1000 new and previously published ITS sequences, focused particularly on Poeae chloroplast group 1 and including broad and increased species sampling compared to previous studies. Deep branches in the combined plastid and combined ITS+ETS trees are generally well resolved, the trees are congruent in most aspects, branch support across the trees is stronger than in trees based on only ITS and fewer plastid regions, and there is evidence of conflict between data partitions in some taxa. In plastid trees, a strongly supported clade corresponds to Poeae chloroplast group 1 and includes Agrostidinae p.p., Anthoxanthinae, Aveninae s.str., Brizinae, Koeleriinae (sometimes included in Aveninae s.l.), Phalaridinae and Torreyochloinae. In the ITS+ETS tree, a supported clade includes these same tribes as well as Sesleriinae and Scolochloinae. Aveninae s.str. and Sesleriinae are sister taxa and form a clade with Koeleriinae in the ITS+ETS tree whereas Aveninae s.str. and Koeleriinae form a clade and Sesleriinae is part of Poeae chloroplast group 2 in the plastid tree. All species of Trisetum are part of Koeleriinae, but the genus is polyphyletic. Koeleriinae is divided into two major subclades: one comprises Avellinia, Gaudinia, Koeleria, Rostraria, Trisetaria and Trisetum subg. Trisetum, and the other Calamagrostis/Deyeuxia p.p. (multiple species from Mexico to South America), Peyritschia, Leptophyllochloa, Sphenopholis, Trisetopsis and Trisetum subg. Deschampsioidea. Graphephorum, Trisetum cernuum, T. irazuense and T. macbridei fall in different clades of Koeleriinae in plastid vs. nuclear ribosomal trees, and are likely of hybrid origin. ITS and matK trees identify a third lineage of Koeleriinae corresponding to Trisetum subsect. Sibirica, and affinities of Lagurus ovatus with respect to Aveninae s.str. and Koeleriinae are incongruent in nuclear ribosomal and plastid trees, supporting recognition of Lagurus in its own subtribe. A large clade comprises taxa of Agrostidinae, Brizinae and Calothecinae, but neither Agrostidinae nor Calothecinae are monophyletic as currently circumscribed and affinities of Brizinae differ in plastid and nuclear ribosomal trees. Within this clade, one newly identified lineage comprises Calamagrostis coarctata, Dichelachne, Echinopogon (Agrostidinae p.p.) and Relchela (Calothecinae p.p.), and another comprises Chascolytrum (Calothecinae p.p.) and Deyeuxia effusa (Agrostidinae p.p.). Within Agrostidinae p.p., the type species of Deyeuxia and Calamagrostis s.str. are closely related, supporting classification of Dey...

Nomenclatural Revision for the Order Scorzonero-Chrysopogonetalia

The order Scorzonero-Chrysopogonetalia describes the dry grasslands of a large area in southeastern Europe, centred around and east of the Adriatic Sea (i.e., ). Most commonly, Scorzonero-Chrysopogonetalia is arranged within the classes Festuco-Brometea or Brachypodio-Chrysopogonetea or it is split into two orders classified within Festuco-Brometea and Thero-Brachypodietea; according to other minor opinions, the order is sometimes assigned to Brachypodio-Brometea, TheroBrachypodietea or Ononido-Rosmarinetea. This report deals with the nomenclatural revision of Scorzonero-Chrysopogonetalia and other correlated syntaxa to sort out the numerous incorrect syntaxon names found in scientific literature. The revision is carried out according to the third edition of the International Code of Phytosociological Nomenclature, and while it focuses on ranks of order, alliance and suballiance, it is also enlarged to include associations quoted in major comprehensive syntaxonomic revisions. As a result, many names and authors' citations of syntaxa are corrected, and the theoretical implications arising from their usage are indicated. To promote nomenclatural stability, a new alliance, Violo pseudogracilisBromopsion caprinae, is described, and the following syntaxa are validated: Hypochoeridion maculatae, Hypochoeridenion maculatae, Astragalo croaticiSeslerietum robustae, Avenulo praeustae-Brometum erecti, Bromo erectiSeslerietum interruptae, Carici vernae-Scabiosetum leucophyllae, Globulario cordifoliae-Scabiosetum leucophyllae, Globulario elongatae-Chrysopogonetum grylli, Minuartio capillaceae-Genistetum pulchellae, Stipo eriocaulis-Caricetum humilis and Stipo pennatae-Genistetum dalmaticae. Additionally, three association names (Asphodelo albi-Filipenduletum vulgaris, Centaureo rupestris-Caricetum humilis and Cymbopogono hirti-Brachypodietum ramosi) are proposed for inversions, and three others (Festuco illyricae-Poetum bulbosae, Lactuco vimineaeBothriochloetum ischaemum and Saturejo montanae-Dichanthietum ischaemum) are corrected. Finally, typifications of 16 syntaxa are given.

Eremopoa is a small genus of annual grasses distributed from Egypt to western China. Phylogenetic analyses of plastid and nuclear ribosomal DNA show that Eremopoa species, together with the monotypic genus Lindbergella and a single species of Poa (P.speluncarum), are nested within the genus Poa, in a clade that we accept as Poasubg.Pseudopoa. Here we accept seven species, four subspecies and four varieties in Poasubg.Pseudopoa. Five new combinations are made: Poaattalica, P.diaphora var. alpina, P.diaphora var. songarica, P.nephelochloides and P.persicasubsp.multiradiata; P.millii is proposed as a replacement name for E.capillaris; and Poa sections Lindbergella and Speluncarae are proposed. We provide a diagnosis for Poasubg.Pseudopoa, synonymy for and a key to the taxa. Eight lectotypes are designated: Eragrostisbarbeyi Post, Eremopoanephelochloides Roshev., Glyceriataurica Steud., Nephelochloatripolitana Boiss. & Blanche, Poacilicensis Hance, Poaparadoxa Kar. & Kir., Poapersicavar.alpina Boiss and Poapersicasubsp.cypria Sam. Eremopoamedica is re-identified as a species of Puccinellia.
