“…The generic placements of these two species have varied over time. Hitchcock (1927) described T. bulbosum , recorded from southern Argentina and southern Chile (Finot et al, 2006), and Parodi (1949) later transferred it to Helictotrichon Besser, as H. bulbosum (Hitchc.) Parodi.…”

“…Finot et al (2005) recognized T. brasiliense as Deschampsia brasiliensis and maintained T. juergensii in Trisetum (with hesitation), and they indicated that neither of the species fits well in Trisetum . On the basis of micromorphological analysis of lemma epidermal characters, Finot et al (2006) demonstrated that neither T. brasiliense nor T. juergensii fit the generic circumscriptions of Helictotrichon, Deschampsia , and Trisetum , but they did not suggest a revised classification for these taxa. Chiapella & Zuloaga (2010) excluded Deschampsia brasiliensis from their taxonomic treatment of Deschampsia for South America and mentioned that its generic placement is unclear.…”

The circumscription of the grass subtribe Calothecinae has undergone several changes since its description. Currently, it comprises Chascolytrum and the recently described genera Laegaardia and Paramochloa.Here we evaluate the circumscription of Calothecinae and the recently proposed infrageneric classification of Chascolytrum based on a phylogeny with more comprehensive taxon and molecular marker sampling than in previous studies. We sampled all Calothecinae genera, all but one Chascolytrum species, two South American Trisetum s.l., and representatives of the subtribes Agrostidinae, Brizinae, Echinopogoninae, Koeleriinae, Phalaridinae, and Torreyochloinae within Poaceae tribe Poeae. We performed Bayesian and Maximum Likelihood analyses of four plastid DNA regions (atpF-atpH, matK, rps16 intron, and trnL-trnF) and two nuclear ribosomal regions (ITS and ETS). Our results revealed that neither Calothecinae nor Chascolytrum is monophyletic, as currently recognized, because Trisetum brasiliense and Trisetum bulbosum are nested within Chascolytrum. We include these two Trisetum species in Calothecinae as incertae sedis. Laegaardia and Paramochloa form a clade that is sister to the Chascolytrum + Trisetum clade, and based on morphological characters, we transfer the former to the new subtribe Paramochloinae. Our Chascolytrum phylogeny is better resolved and supported than in previous studies, and based on these results, we divide Chascolytrum into nine genera, including two new ones: Boldrinia (gen. nov.), Calotheca, Chascolytrum, Erianthecium, Lombardochloa, Microbriza, Poidium, Rhombolytrum, and Rosengurttia (gen. nov.). We provide a key to Calothecinae genera, descriptions of the genera, nomenclatural information, and keys to species of each genus. In addition, six new combinations are proposed.

“…En Trisetum las panículas son espiciformes, mientras que en D. danthonioides las panículas son laxas. Además en Deschampsia la arista dorsal está insertada en la base de la lema, por el contrario las especies de Trisetum tienen la arista dorsal insertada en la parte media de la lema (Finot et al 2005). tienen ligeras diferencias con la descripción proporcionada en la revisión del género Deschampsia (Chiapella & Zuloaga 2010).…”

Summary: New records and notes on the genus Peyritschia (Poaceae: Pooideae: Aveninae) in Peru. The genus Peyritschia is recorded from Peru for the first time, with two species involved, P. pringlei and P. deyeuxioides. The genus is described and a key to recognize it from the related genera Trisetum and Deschampsia is provided. P. pringlei and P. deyeuxioides are described, including synonymy, geographical distribution and habitat. These species are illustrated based on their vegetative and reproductive characters. Herbarium specimens are cited and a key to the two species is supplied.Key words: Poaceae, Pooideae, Peyritschia, Peru.Resumen: Se cita por primera vez el género Peyritschia para el Perú, representado por dos especies, P. pringlei y P. deyeuxioides. El género se describe y se diferencia en una clave de los géneros afines Trisetum y Deschampsia. P. deyeuxioides y P. pringlei se describen, incluyéndose sinónimos, distribución geográfica y hábitat. Las dos especies se ilustran sobre la base de sus caracteres vegetativos y reproductivos. Se citan materiales de referencia y se provee una clave que permite diferenciarlas.
