“…Koeleria differs from Trisetum by having lemmas muticous, mucronate or inconspicuously-awned apically or subapically (Cafferty et al 2000, Quintanar et al 2010). The taxonomic history of Koeleria is reviewed in detail by Quintanar and Castroviejo (2013). Koeleria and Trisetum are known to hybridize.…”

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...

Español. El objetivo de este trabajo es realizar un catálogo de la flora, de las comunidades vegetales y el estudio del dinamismo sucesional y del paisaje vegetal de la Zona de Especial Conservación (ZEC) Sierra de Camarolos (ES6170012), situada en la provincia de Málaga (Andalucía, España) con una superficie de 8.691 Ha. Presenta macrobioclima de tipo mediterráneo con termotipos meso y supramediterráneo y ombrotipos subhúmedo y húmedo. Está compuesta litológicamente de modo mayoritario por materiales calizo-dolomíticos, arcillosos y margo-yesíferos, con relieve kárstico y ondulado-escarpado y altitudes entre 500 y 1640 m. Se encuentra en la provincia fitogeográfica Bética (región Mediterránea), sector Antequerano, subsector Antequerano (zonas margo-yesíferas) y subsector Torcalense (zonas calizodolomíticas). El catálogo florístico se compone de 879 taxones, destacando la presencia de numerosas especies amenazadas y/o legalmente protegidas a nivel autonómico como Narcissus pseudonarcissus subsp. nevadensis, Narcissus assoanus, Festuca elegans, Amelanchier ovalis, Prunus insititia, P. mahaleb, Sorbus aria, Hieracium texedense, Scrophularia viciosoi, Quercus faginea subsp. alpestris, Sarcocapnos baetica y Saxifraga biternata. Otras especies de interés son nuevas citas a nivel fitogeográfico y/o provincial. Se han catalogado 73 comunidades y asociaciones vegetales, entre las que destacan como novedades sintaxonómicas una nueva subalianza (Fumano hispidulae-Hippocrepidenion bourgaei suball. nova) y 5 nuevas asociaciones: la vegetación rupícola orófila sobre dolomías (Hieracietum baetici-texedensis ass. nova), los cardales verticícolas temporihigrófilos (Eryngio aquifolii-Cynaretum baeticae ass. nova), los majadales basófilos (Thrincio hispidae-Poetum bulbosae ass. nova), los albaidares gipsícolas (Hippocrepido bourgaei-Anthyllidetum cytisoidis ass. nova) y los piornales xeroacánticos supra-mesomediterráneos (Festuco segimonensis-Erinaceetum anthyllidis ass. nova). También se proponen 3 nuevas subasociaciones: espartal termófilo (Thymo gracilis-Stipetum tenacissimae thymetosum capitati subass. nova), vallicares (Gaudinio fragilis-Agrostietum castellanae festucetosum amplae subass. nova) y encinares mesomediterráneos termófilos (Paeonio coriaceae-Quercetum rotundifoliae pistacietosum lentisci subass. nova). El dinamismo sucesional se expresa en 8 series de vegetación. 3 series climatófilas: una mesomediterránea de Quercus rotundifolia, y 2 de Quercus faginea, respectivamente antequerana y torcalense. 3 series edafoxerófilas puntuales: una termófila subrupícola de Olea europaea subsp. sylvestris, otra karsticícola más ombrófila de Pistacia terebinthus y una gipsícola de Pinus halepensis. Existen también una serie edafohigrófila de fresnedas (Fraxinus angustifolia) y otra de adelfar (Nerium oleander). En los frecuentes hábitats rocosos y de gleras se describen 2 geopermaseries: una calcícola caracterizada por Saxifraga biternata, S. reuteriana y S. camposii y otra dolomitícola con Hieracium texedense e H. baeticum y, muy escaso, con Sarcocapnos baetica. Las geopermaseries dulceacuícolas lagunares están caracterizadas por R. peltatus subsp. saniculifolius y subsp. peltatus, Zannichellia palustris y Chara vulgaris subsp. crassicaulis. Finalmente la geopermaserie temporihigrófila de suelos vérticos se caracteriza por Eryngium caespitiferum, Phalaris caerulescens y Festuca ampla. En la ZEC existen 15 grandes unidades de paisaje zonopotencial, caracterizados en gran medida, y en el caso de los bosques, por la presencia de Quercus rotundifolia y Q. faginea, con diferencias entre el paisaje vegetal de los dos subsectores de la ZEC, Torcalense y Antequerano.English. The objective of this work is to catalogue the flora and plant communities and studying the successional dynamism of the vegetation and the landscape of the Special Conservation Zone (ZEC) Sierra de Camarolos (ES6170012) which is located in the province of Malaga (Andalusia, Spain) with an area of 8.691 Ha. The macrobioclimate is Mediterranean with mesomediterranean and supramediterranean thermotypes (vegetation belts) and subhumid-humid ombrotypes. Geologically, dominant rocks are limestone and dolomite, clays and gypsum, with karstic and wavy-steep relief and altitudes between 500 and 1640 m. The ZEC is placed in the Baetica phytogeographical province (Mediterranean Region) included in the Antequerano sector with differentiated areas: Antequerano subsector (clays-gypsum substrates) and Torcalense subsector (limestones and dolomites substrates). The floristic list consists of 879 taxa, emphasizing the presence of numerous threatened and / or legally protected species at the regional level such as Narcissus pseudonarcissus subsp. nevadensis, Narcissus assoanus, Festuca elegans, Amelanchier ovalis, Prunus insititia, P. mahaleb, Sorbus aria, Hieracium texedense, Scrophularia viciosoi, Quercus faginea subsp. alpestris, Sarcocapnos baetica and Saxifraga biternata. Other species of interest are new records at the phytogeographical and/ or provincial level. A total of 73 plant communities and associations have been catalogued, including syntaxonomic novelties as a new suballiance (Fumano hispidulae-Hippocrepidenion bourgaei subal. nova) and 5 new associations: rupicolous vegetation on dolomites (Hieracietum baetici-texedensis ass. nova), tall-herb nitrophilous vegetation on clay temporarily wet soils ((Eryngio aquifolii-Cynaretum baeticae ass. nova), basophyllous pastures (Thrincio hispidae-Poetum bulbosae ass. nova), gypsicolous shrublands (Hippocrepido bourgaei-Anthyllidetum cytisoidis ass. nova) and supra-mesomediterranean cushion shrublands (Festuco segimonensis-Erinaceetum anthyllidis ass. nova). Moreover, 3 new subassociations are proposed: thermophyllous graminoid perennial vegetation (Thymo gracilis-Stipetum tenacissimae thymetosum capitati subass. nova), wet meadows (Gaudinio fragilis-Agrostietum castellanae festucetosum amplae subass. nova) and low mesomediterranean oak forests (Paeonio coriaceae-Quercetum rotundifoliae pistacietosum lentisci subass. nova). Succesional dynamism of plant communities is expressed in 8 vegetation series. 3 series are climatophilous: one mesomediterranean of Quercus rotundifolia and two of Quercus faginea. 3 series are edaphoxerophilous: one thermophilic subrupicolous of Olea europaea subsp. sylvestris, one karstic ombrophile of Pistacia terebinthus and one on gypsum soils of Pinus halepensis. There are also 2 edaphohygrophyllous series: one of Fraxinus angustifolia and another one of Nerium oleander. In the frequent rocky and stony ground habitats, 2 geopermaseries are described: a calcicolous one, characterized by Saxifraga biternata, S. reuteriana and S. camposii and another dolomiticolous one, with Hieracium texedense and H. baeticum and, very scarce, with Sarcocapnos baetica. The freshwater ponds geopermaseries are characterized by Ranunculus peltatus, subsp. saniculifolius and subsp. peltatus, Zannichellia palustris and Chara vulgaris subsp. crassicaulis. Finally, the temporary hygrophilic geopermaserie of clay soils is characterized by Eryngium caespitiferum, Phalaris caerulescens and Festuca ampla. In the ZEC there are 15 large zonopotential landscape units, characterized to a great extent, and in the case of forests, by the presence of Quercus rotundifolia and Q. faginea, with differences between the vegetation landscape of the two subsectors of the ZEC, Torcalense and Antequerano.

Rocky pastures dominated by Stipa austroitalica in the south-east of Italy were classified within an endemic alliance, Hippocrepido glaucae-Stipion austroitalicae, originally assigned to a Balkan order (Scorzoneretalia villosae). Actually, the distribution area of S. austroitalica extends further westwards and large patches are found on the south-east side of the Pollino Massif. This study aims to describe and characterise the plant communities dominated by S. austroitalica in this area and analyse their floristic and chorological relationships with other associations of Hippocrepido-Stipion. Moreover, their syntaxonomy is discussed in the context of the Italian and south European dry grasslands biogeography. The grasslands were studied on the basis of 19 phytosociological relevés. A larger data set, including 185 relevés with S. austroitalica, was used to visualise the relationships among the associations through nonmetric multi-dimensional scaling ordination. The results allowed the description of a new association, Bupleuro gussonei-Stipetum austroitalicae, classified within Hippocrepido-Stipion. As a consequence, the alliance synrange was extended up to the Pollino Massif. The Hip pocrepido-Stipion, together with Cytiso spinescentis-Bromion erecti, was arranged in Euphorbietalia myrsinitidis, an endemic order of the Italian peninsula. The proposed scheme upgrades the syntaxonomy and nomenclature of the dry grasslands vegetation of central and southern Italy.
