“…Although our unpublished DNA data support Koordersiochloa as sister to Meliceae, and Brylkinia as sister to these, Schneider et al (2011) andHochbach et al (2015) found support for placing Koordersiochloa within Meliceae. Here we place Koordersiochloa in Meliceae, and unite the tribes Brylkinieae and Meliceae in supertribe Melicodae.…”

“…Placement of all genera within tribes was consistent between the two classifications except where the tribes were placed in synonymy or split. Kellogg (2015) included Lygeum in Nardeae (Schneider et al, 2009(Schneider et al, , 2011Hochbach et al, 2015), and Ampelodesmos in Stipeae, rather than in their own monotypic tribes (Soreng et al, 2015b). Brylkinia and Koordersiochloa (Brylkinieae) of Soreng et al (2015b) were merged into Meliceae by Kellogg (2015).…”

“…Among the Duthieeae and other Pooideae, Phaenosperma is morphologically odd with globose spikelets that disarticulate below the glumes, pseudopetiolate and resupinate leaf blades (Schneider et al, 2011), and it is apparently widely reticulate in origin among tribes Duthieeae, Stipeae, and possibly Meliceae (Hochbach et al, 2015). We retain Ampelodesmos in the Ampelodesmeae separate from Stipeae based on evidence of a reticulate origin with Duthieeae (Romaschenko et al, 2012(Romaschenko et al, , 2014.…”

We present a new worldwide phylogenetic classification of 11 506 grass species in 768 genera, 12 subfamilies, seven supertribes, 52 tribes, five supersubtribes, and 90 subtribes; and compare two phylogenetic classifications of the grass family published in 2015 (Soreng et al. and Kellogg). The subfamilies (in descending order based on the number of species) are Pooideae with 3968 species in 202 genera, 15 tribes, and 30 subtribes; Panicoideae with 3241 species in 247 genera, 13 tribes, and 19 subtribes; Bambusoideae with 1670 species in 125 genera, three tribes, and 15 subtribes; Chloridoideae with 1602 species in 124 genera, five tribes, and 26 subtribes; Aristidoideae with 367 species in three genera, and one tribe; Danthonioideae with 292 species in 19 genera, and one tribe; Micrairoideae with 184 species in eight genera, and three tribes; Oryzoideae with 115 species in 19 genera, four tribes, and two subtribes; Arundinoideae with 40 species in 14 genera, two tribes, and two subtribes; Pharoideae with 12 species in three genera, and one tribe; Puelioideae with 11 species in two genera, and two tribes; and the Anomochlooideae with four species in two genera, and two tribes. We also include a radial tree illustrating the hierarchical relationships among the subtribes, tribes, and subfamilies. Newly described taxa include: supertribes Melicodae and Nardodae; supersubtribes Agrostidodinae, Boutelouodinae, Gouiniodinae, Loliodinae, and Poodinae; and subtribes Echinopogoninae and Ventenatinae.

RESUMENEl endemismo es uno de los principales aspectos que trata la biogeografía histórica y es uno de los criterios más importantes para establecer las prioridades de conservación de las especies. En el mundo, más del 90% de las plantas que se encuentra en alguna categoría de amenaza son endémicas de un sólo país. En Chile, un 45% de las especies de plantas vasculares son endémicas. Actualmente este número incluye 83 géneros y 4 familias endémicas del país; éstos son valores elevados en comparación con el resto de Latinoamérica. Sin embargo, la alta tasa de cambios producidos por los estudios de sistemática molecular en la taxonomía ha generado modificaciones en estos números. Este trabajo pretende discutir dichas modificaciones y así contribuir a la correcta delimitación de estos géneros endémicos. Utilizando bases de datos y bibliografía actualizadas, se llevó a cabo una revisión exhaustiva sobre estos géneros. Se sustrajeron de la lista aquellos géneros con registros fuera del país y aquellos que cuentan con evidencia suficiente para cambiar su estatus taxonómico. Se entrega una revisión crítica de la bibliografía sistemática respecto de los géneros en cuestión, discutiendo principalmente aquellos que a la luz de la literatura presentaron ambigüedades en su clasificación. PALABRAS CLAVE:Endemismo, Sistemática molecular, Filogenia molecular, Conservación biológica. ABSTRACTEndemism is one of the main considerations in historical biogeography and one of the most important criteria when establishing conservation priorities. Worldwide, more than 90% of the plants listed in conservation categories are endemic to one country. In Chile, 45% of the flora is endemic, currently considering 83 endemic genera and 4 endemic families, elevated numbers compared to the rest of Latinamerica. However, the high rate of changes in taxonomy, based on studies of molecular systematics has produced modifications in this list. This study aims at discussing such modifications and in this way, contribute to the correct delimitation of our endemic genera. Using updated databases and bibliographic sources, an exhaustive revision of these genera was carried out. Genera with registries outside of the country, as well as those that had enough evidence to change their taxonomic status were subtracted from the list. A critical revision of the systematic bibliography available is provided, emphasizing the discussion on those genera with ambiguous classification status.

Evolution and Taxonomy of the Grasses (Poaceae): A Model Family for the Study of Species‐Rich Groups

The grass family Poaceae, with 11 500 species, is economically, ecologically, and evolutionarily one of the most successful species‐rich groups. Because of this, it represents a model family for the study of speciose taxa. Routine DNA sequencing has accelerated progress in the evolutionary study of grasses, leading to more stable taxonomic classifications; prototype DNA barcoding systems; and a better understanding of their biogeography, physiology, and ecology. This article examines the remaining challenges in the evolutionary and taxonomic study of grasses. These include assessing the monophyly of genera, improving species‐level phylogenetics, establishing a comprehensive DNA barcoding system, understanding diversification in geological time and geographical/ecological space, understanding morphological and physiological trait evolution (such as C 4 photosynthesis, polyploidy, and spikelet morphology), and understanding co‐evolution with other organisms such as herbivores and endophytic/mycorrhizal microbes.
