“…Advances in Neotropical Xyridaceae are therefore based on many local floras and new species descriptions (e.g. Kral 1992Kral , 1998Kral , 2005Kral & Wanderley 1993, 1995Motta & Wanderley 2013Silva & Wanderley 2013;Wanderley 2010Wanderley , 2011Wanderley & Silva 2009).…”

Poales represents a major part of Angiosperm and Monocot diversity. The families encompass ca. 20,000 species which is about 7% of the Angiosperms and 33% of the Monocots. Bromeliaceae, Cyperaceae, Eriocaulaceae, Juncaceae, Mayacaceae, Poaceae, Rapateaceae, Thurniaceae, Typhaceae, and Xyridaceae are the families represented in the Neotropics. In general terms some areas in the Neotropics could be considered hotspots for Poales with a high number of species in several genera and several centers of endemism-the Guayana Shield, Espinhaço Range and Atlantic Forest are highly diverse in Poales. In terms of the Brazilian flora, the order is well represented in the entire country with almost 4,400 species. It represents more than 50% of the total number of species of Monocotyledons in Brazil. The main goal here is to summarize the available information and provide an overview of the Poales in the Neotropics. The state of knowledge for each family, focused on the Brazilian flora, is provided and reinforces the importance of new studies in key-groups looking beyond the understanding of their diversity on the continent but also the conservation of the species.

Resumo É apresentado o estudo taxonômico da família Xyridaceae para o estado do Paraná, a qual é representada apenas pelo gênero Xyris, com 22 espécies típicas de ambientes campestres. São referidos três novos registros para o estado: Xyris glandacea, X. metallica e X. uninervis, ampliando a área de distribuição destas para a Região Sul do Brasil. Outras novidades são um novo sinônimo (Xyris simulans var. subtortula sob X. asperula) e o restabelecimento de X. dusenii. São apresentados chave de identificação, descrições, comentários, ilustrações e dados sobre a distribuição geográfica das espécies.

“…The most recent monograph of Xyridaceae in Brazil (Smith and Downs 1968) recognized 115 species of Xyris . However, a large number of Brazilian species have been described since (Kral and Smith 1980, 1982, Wanderley 1983, 1986, Wanderley and Cerati 1987, Kral and Wanderley 1988a, 1988b, 1993, Wanderley 2003, 2010, Mota and Wanderley 2013, Mota and Wanderley 2014, Wanderley and Mota 2015, Lozano et al 2016), increasing the number of taxa by approximately 44% over the last three decades.…”

A nomenclatural revision of fifteen taxa of Xyris (Xyridaceae) described by L.A. Nilsson (1892) is presented as part of a taxonomic revision of the genus in Brazil. All the protologues and type collections of these taxa were studied. The type collections were examined in the respective herbarium collections where they are preserved and complemented by images available on herbarium websites and from JSTOR Global Plants. Lectotypes were selected for Xyris cristata L.A.Nilsson, X. glaziowii L.A.Nilsson and X. insignis L.A.Nilsson. The holotypes, of X. glandacea L.A.Nilsson and X. stenophylla L.A.Nilsson, were discovered at the herbaria of Uppsala (UPS) and Berlin (B) respectively, and provided with their correct determinations.
