Based on recent molecular and morphological studies we present a modern worldwide phylogenetic classification of the ± 12074 grasses and place the 771 grass genera into 12 subfamilies (Anomochlooideae, Aristidoideae, Arundinoideae, Bambusoideae, Chloridoideae, Danthonioideae, Micraioideae, Oryzoideae, Panicoideae, Pharoideae, Puelioideae, and Pooideae), 6 supertribes (Andropogonodae, Arundinarodae, Bambusodae, Panicodae, Poodae, Triticodae), 51 tribes (Ampelodesmeae, Andropogoneae, Anomochloeae… 
A key to the North American genera of Stipeae (Poaceae, Pooideae) with descriptions and taxonomic names for species of Eriocoma, Neotrinia, Oloptum, and five new genera: Barkworthia, ×Eriosella, Pseudoeriocoma, Ptilagrostiella, and Thorneochloa
A key to the native and introduced genera of North American Stipeae, and an overview of the tribe in North America and worldwide are given, are given.
Molecular phylogenetic analysis resolves Trisetum (Poaceae: Pooideae: Koeleriinae) polyphyletic: Evidence for a new genus, Sibirotrisetum and resurrection of Acrospelion
To investigate the evolutionary relationships among the species of Trisetum and other members of subtribe Koeleriinae, a phylogeny based on DNA sequences from four gene regions (ITS, rpl32‐trnL
Advances in the phylogeny of the South American cool-season grass genus Chascolytrum (Poaceae, Pooideae): a new infrageneric classification
The use of single-copy nuclear genes and morphological data for future phylogenetic reconstructions encompassing Chascolytrum is highlighted and the new infrageneric classification proposed for the group under the genus Briza is discussed.
Phylogeny and taxonomic synopsis of PoasubgenusPseudopoa (including Eremopoa and Lindbergella) (Poaceae, Poeae, Poinae)
Phylogenetic analyses of plastid and nuclear ribosomal DNA show that Eremopoa species are nested within the genus Poa, in a clade that is accepted as Poasubg.Pseudopoa, synonymy for and a key to the taxa.
A worldwide phylogenetic classification of the Poaceae (Gramineae) II: An update and a comparison of two 2015 classifications
A new worldwide phylogenetic classification of 11 506 grass species in 768 genera, 12 subfamilies, seven supert tribes, 52 tribes, five supersubtribes, and 90 subtribes is presented and a radial tree illustrating the hierarchical relationships among the subtribes, tribes, and subfam families is included.
Biogeography, timing, and life‐history traits in the PPAM clade: Coleanthinae (syn. Puccinelliinae), Poinae, Alopecurinae superclade, Miliinae, and Avenulinae and Phleinae (Poaceae, Pooideae, Poeae)
A biogeographic analysis of the PPAM clade of Poeae Plastid DNA Group 2, which includes 12 subtribes of C3 grasses, suggests that alpine and subalpine habitats were ancestral and high tolerance of saline and alkaline conditions arose between the Pliocene and Pleistocene.
A comprehensive species sampling sheds light on the molecular phylogenetics of Calothecinae (Poaceae, Pooideae, Poeae): Evidence for a new subtribe and multiple genera within the Chascolytrum clade
The circumscription of Calothecinae and the recently proposed infrageneric classification of Chascolytrum is evaluated based on a phylogeny with more comprehensive taxon and molecular marker sampling and six new combinations are proposed.
Reproductive traits related to anemophily and insect visitors in two species of Poaceae from the Brazilian Atlantic rainforest
New data concerning the floral biology and anemophily of herbaceous Poaceae in the Brazilian Atlantic Rainforest is brought, suggesting the insect-assisted anemphily in L. ligulata is suggested.


A molecular phylogeny and classification of the Cteniinae, Farragininae, Gouiniinae, Gymnopogoninae, Perotidinae, and Trichoneurinae (Poaceae: Chloridoideae: Cynodonteae)
The goals of this study were to reconstruct the evolutionary history of the tribe Cynodonteae, emphasizing these twenty genera using molecular data with increased species sampling and the recognition of six subtribes.
A molecular phylogeny and classification of the Eleusininae with a new genus, Micrachne (Poaceae: Chloridoideae: Cynodonteae)
A molecular phylogeny and classification of the Eleusininae with a new genus, Micrachne, finds about 212 species in 31 genera found primarily in low latitudes in Africa, Asia, Australia, and the Americas.
Phylogeny and evolution in the Crinipes group of grasses (Arundinoideae: Poaceae)
The arundinoid genera Crinipes, Nematopoa, Styppeiochloa, Piptophyllum and Zenkeria are shown to form a monophyletic clade, based on leaf anatomical and morphological data. This clade, here called
Molecular and morphological evidence for a new grass genus, Dupontiopsis (Poaceae tribe Poeae subtribe Poinae s.l.), endemic to alpine Japan, and implications for the reticulate origin of Dupontia and Arctophila within Poinae s.l.
The investigation suggests that the most recent shared ancestor of the DAD clade evolved from a single hybridization event, as a hexaploid, probably in western Beringia, and is considered to be within the Poinae–Alopecurinae clade excluding Poa.
A classification of the Chloridoideae (Poaceae) based on multi-gene phylogenetic trees.
Phylogenese Studies in the Paniceae (Poaceae-Panicoideae): Ocellochloa, a New Genus from the New World
A phylogenetic analysis of Paniceae based on cpDNA sequence data (ndhF) was performed with special emphasis on section Stolonifera of Panicum, resulting in Ocellochloa being described as a new genus.
A phylogenetic evaluation of Panicum sects. Agrostoidea, Megista, Prionitia and Tenera (Panicoideae, Poaceae): Two new genera, Stephostachys and Sorengia
All taxa, previously considered in these subgenera and sections, are now included in the new genera Stephostachys and Sorengia, which are based on morphological and molecular characters.
A phylogenetic analysis of chloroplast DNA restriction site variation inPoaceae subfam.Pooideae
A phylogenetic analysis was conducted on chloroplast DNA restriction site variation in 34 genera of grasses (familyPoaceae), including 28 genera from subfamilies, suggesting that the pooid spikelet is plesiomorphic in Pooideae, and that spikelets with one floret, and those with glumes longer than the first lemma, each have evolved more than once withinPooideae.
Centropodieae and Ellisochloa, a new tribe and genus in Chloridoideae (Poaceae)
A phylogenetic analysis of 127 species using seven plastid regions to infer the evolutionary relationships of Centropodia, M. papposa, and M. rangei shows they are sister to the remaining tribes in Chloridoideae and provides the carbon isotope ratios for four species indicating that Merxmuellera pappos and M- rangei are photosynthetically C3, and CentropODia glauca and C. mossamdensis are C4.
Phylogeny of New World Paspalum (Poaceae, Panicoideae, Paspaleae) based on plastid and nuclear markers
Phylogenetic relationships among species of Paspalum were partially recovered possibly due to reticulation events among species, autopolyploidization and apomixis, thus obscuring the infrageneric classification.
