“…A series of recent papers has clarified numerous lower-level taxonomic issues among multiple Eurasian taxa of Agrostis , Calamagrostis and Deyeuxia (many from the far East) and described new species, most not yet included in molecular studies (Paszko and Nobis 2010, Paszko 2011, 2012a, b, 2013, 2014a, b, c, d, e, 2015, 2016, Paszko and Ma 2011, Paszko and Chen 2013, Paszko and Pendry 2013a, b, Paszko and Soreng 2013, Paszko et al 2013, 2015, Nobis et al 2014). In Mexico and Central America, species are treated in Calamagrostis (Beetle 1987, Pohl and Davidse 1994, Peterson et al 2004).…”

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...

“…Therefore, not all specimens need to be phenotypically intermediate. Recent studies have shown that morphological characters of hybrids are not always intermediate between those of the parental species, and hybrids show a mosaic of parental, intermediate and extreme characters (Rieseberg 1995, Paszko and Nobis 2010). Specimens belonging to S. manrakica can probably also exhibit wider morphological variability.…”

Stipa adamii M. Nobis sp. nov. (Poaceae), endemic to Kazakhstan, is described and illustrated. The species belongs to the section Smirnovia Tzvel. and is distributed in the central Karatau Mountains (western Tian‐Shan). It is morphologically close to Stipa karataviensis Roshev. but is easily distinguishable by longer glumes, lemmas, awns and the callus. The awn is scabrous in the lower part and the callus is bearded in S. adamii whereas both organs are glabrous in S. karataviensis. Characters distinguishing S. karataviensis and S. adamii are presented in a table, together with photographs of the callus. The analysis of morphological characters of the taxa provides new information on their variability. A key to the species of Stipa sect. Smirnovia occurring in Kazakhstan, typification of the name S. manrakica and synonymization of the name S. saurica as a syn. nov. are included.

Monocots include ca. 74 000–85 000 species. It is one of the most species rich, ecologically and economically important groups of plants. At the same time, monocots are a key component of ecosystems and have utilitarian significance. In agriculture the majority of the biomass produced comes from monocots. Many plants from this group are used as ornamentals or medicinal plants. This work is devoted to the study of the nomenclature of monocot hybrids in the flora of Ukraine. In general, there are many unsolved problems in the nomenclature of hybrids. Numerous names require clarification. The aim of this study is to compile a list of intergeneric and interspecific hybrids of monocots in the flora of Ukraine. This list includes wild hybrids, as well as cultivated ones that grow spontaneously in the wild. The list of hybrids is compiled mainly on the basis of literary sources. The names of taxa and nothotaxa are indicated according to IPNI. Formulas of the hybrids, basionyms and synonyms are given for the hybrids. The list of monocots' hybrids in the flora of Ukraine offered here includes 87 hybrids. There are many hybrids in the following families: Cyperaceae (20), Orchidaceae (25), Poaceae (22) and Potamogetonaceae (8). In other families there are not many hybrids: Amaryllidaceae (1), Araceae (2), Asparagaceae (1), Commelinaceae (1), Iridaceae (1), Juncaceae (4), Liliaceae (1), Typhaceae (1). There were a number of difficulties during the preparation of this article: 1) there is not enough information, the hybridization of plant species is poorly studied in Ukraine, 2) it is difficult to draw a clear line between hybrids and species of hybridogenic origin, 3) disputed status of parental taxa (i.e. different researchers consider parental taxa in different ranks). Therefore, this list should be considered preliminary.
