Epiphytes are hyper‐diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non‐vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer‐reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non‐vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non‐vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

-(Flora of the Serra do Cipó, Minas Gerais: Bromeliaceae -Tillandsioideae). The taxonomic treatment of Tillandsioideae (Bromeliaceae) for the project "Flora of Serra do Cipó, Minas Gerais, Brasil" is presented. The su bfamily is represented in the study area by four genera and 24 species: Cnecpvctgc (2 species), Tcekpcgc (1 species), Vknncpfukc (9 species) and Xtkgugc (12 species). Descriptions and illustrations as well as comments on the taxonomy, geographic distribution, phenology, and keys to genera and species are presented. A new synonym, Xtkgugc"oqpceqtwo"L.B.Sm., is considered under the concept of X0"uejycemgcpc"Mez. Cnecpvctgc"jcvuejdcejkk is rediscovered.Resumo -(Flora da Serra do Cipó, Minas Gerais, Brasil: Bromeliaceae -Tillandsioideae).

These molecular markers will be valuable tools to aid in understanding the biology of P. pseudocaryophyllus and to detect ongoing consequences of its exploitation, in the context of conservation genetics.

A checklist of 11 genera and 41 species of Bromeliaceae occurring in the state of Mato Grosso do Sul (MS) is presented. Of the total number of species, fi ve are endemic and belong to the genera Dyckia and Tillandsia. The subfamily Pitcairnioideae is the richest in number of genera and species, including taxa that are rare in Brazil (Deuterocohnia and Fosterella). Tillandsioideae is the richest subfamily in species number plus one infraspecifi c taxon; however, it is only represented by Tillandsia, and most species are widely distributed all over Brazil and/or nearby countries. Bromelioideae, a subfamily characteristic of the Atlantic rainforest is less represented. This checklist updates the number of species in Mato Grosso do Sul, when compared to the Offi cial Brazilian Plant Checklist.
