Abstract	Amazonia, despite being famous as the most prominent tropical forest, is currently suffering high rates of degradation, with recurrent fires and deforestation, which could shortly lead it to be classified as a biodiversity hotspot for conservation. Although the known flora of the domain displays exceptional richness, its diversity is far from being well known, with several new species being described each year and lots of areas still poorly collected. During the preparation of a revision of Hyptidendron (Lamiaceae, subtribe Hyptidinae), a small genus with 21 species, unidentified and unmatched specimens from the Amazonian domain were uncovered. Here we describe and illustrate these specimens as Hyptidendron dorothyanum sp. nov., named in honor of Sister Dorothy Stang, murdered for her support for the biodiversity of the Amazon and her defence of the rights of local people. The new species, currently known from just two gatherings from Amazonas and Pará States is compared with its most closely related species, Hyptidendron canum, H. arboreum, H. asperrimum and H. leucophyllum. We also provide a distribution map, a preliminary conservation assessment, as well as comments on the phenology and ecology of the new species. This paper calls attention to the importance of the conservation of Amazonia and its rich but still not completely known diversity.

Abstract	Paepalanthus, in its current sense, is the most diverse genus of Eriocaulaceae in the Neotropics, comprising about 400 species. Previous studies have consistently found that the genus is not monophyletic, also being morphologically heterogeneous and diagnosable by a set of homoplasies; thus, the current circumscription needs to be revised. The new classification proposed here uses a comprehensive phylogeny of Paepalanthus and closely related genera as a framework and an evaluation of a set of morphological characters using ancestral state reconstruction, which allowed the recognition of strongly supported clades with morphological diagnosability. We propose the recognition of 12 genera in the clade encompassing Paepalanthus and allied groups, including six new genera (Coracoralina, Floralia, Giuliettia, Gnomus, Hydriade, Nisius), two new statuses (Cryptanthella, Monosperma), the reestablishment of Actinocephalus, Lachnocaulon, and Tonina, and a recircumscription of Paepalanthus. In this new circumscription, Paepalanthus comprises 257 species, most of them restricted to the Brazilian campos rupestres. Among the proposed genera, nine have potential morphological synapomorphies, one has a restricted geographical distribution, and the other two can be recognized by a combination of characters. Newly generated seed morphology data is consistent within the different genera and plays an important role in their recognition. A total of 136 new combinations are hereby proposed. We provide a genus‐level identification key, as well as generic descriptions, diagnostic features, photos illustrating their morphological diversity, maps and notes on distribution, and lists of species by genus.

Abstract	Paepalanthus is the second largest genus of Eriocaulaceae, with about one-third of the species recorded for the family, but it has not received a recent comprehensive taxonomic treatment. Detailed taxonomic studies show that many names currently in use are actually synonyms. In addition, it was necessary to lectotypify some names. Twenty-five synonyms, associated with 15 species and 10 varieties, and 18 lectotypifications in Paepalanthus are here presented, yielding a revised total of 395 species in the genus, 327 of which occur in Brazil. For each taxon treated here we provide taxonomic status, typification, synonymy, nomenclatural notes, comments, and distribution data.

Abstract	A recent phylogenetic tree for the large paraphyletic genus Paepalanthus showed that the genus Actinocephalus is also paraphyletic with two species of Paepalanthus nested within it: Paepalanthus macrocephalus and Paepalanthus camptophyllus. These species have the diagnostic morphological traits of Actinocephalus, but they are too small to be seen in Paepalanthus macrocephalus and difficult to interpret in Paepalanthus camptophyllus, which has resulted in them being overlooked until now. Furthermore, Paepalanthus macrocephalus has a challenging circumscription, with several putative synonyms whose nomenclatural confusion has persisted for decades. Here we analyzed the morphology of Paepalanthus camptophyllus and Paepalanthus macrocephalus to confirm their relationship with other species of Actinocephalus as shown in the phylogeny and to investigate the diagnostic features that distinguish these species in Actinocephalus. The opportunity was also taken to evaluate putative synonyms of Paepalanthus macrocephalus and Paepalanthus camptophyllus, and to include the remaining variety of A. phaeocephalus (Paepalanthus phaeocephalus var. foliosus) in Actinocephalus, which was lacking in the revision of the genus. Four new combinations and eight lectotypes are provided, as well as six new synonyms. We also provide comments on diagnostic characteristics, distribution, and notes on Actinocephalus.

Abstract	A new species of Macrotorus (Monimiaceae) from the Brazilian Atlantic rainforest is here described and illustrated: Macrotorus genuflexus. This species, restricted to the Poço das Antas Biological Reserve (situated in the central region of Rio de Janeiro state, Brazil), is the second in the genus Macrotorus. The new species description is based on morphological and cytogenetic (karyotype and genome size) comparative analyses. We also report a new record of Macrotorus utriculatus for the state of Bahia, confirming a potential distribution modelling prediction, and provide comments for the conservation of both species.

Abstract	A new species, Hyptidendron roseum, from the Chapada dos Veadeiros region, Goiás state, is described and illustrated. It can be distinguished from its congeners by the combination of inflorescences composed of a unilateral cymose structures, sessile to subsessile leaves, a ring of trichomes in the throat of the calyx tube, and a dense indumentum of white uniseriate trichomes covering much of the plant. The new species is compared with similar species such as H. unilaterale and H. albidum. New specimens of another species, H. unilaterale, formerly known only from the type, were identified in herbaria and collected in the field. Photos in vivo of this species are provided for the first time, accompanying a full description and an illustration. We assess its conservation status and comment on its distribution, ecological aspects, and identification.

Abstract	We describe and illustrate Paepalanthus fabianeae, a new species of Eriocaulaceae from the central portion of the Espinhaço Range in Minas Gerais, Brazil. Previous phylogenetic evidence based on analyses of nuclear (ITS and ETS) and plastid (trnL-trnF and psba-trnH) sequences revealed P. fabianeae as belonging to a strongly supported and morphologically coherent clade containing five other species, all of them microendemic, restricted to the Espinhaço range. Due to the infrageneric classification of Paepalanthus being highly artificial, we preferred not assigning P. fabianeae to any infrageneric group. Paepalanthus fabianeae is known from two populations growing in campos rupestres (highland rocky fields) in the meridional Espinhaço Range. The species is characterized by pseudodichotomously branched stems, small, linear, recurved, and reflexed leaves, urceolate capitula, and bifid stigmas. Illustrations, photos, the phylogenetic position, and a detailed description, as well as comments on habitat, morphology, and affinities with similar species are provided. The restricted area of occurrence allied with threats to the quality of the habitat, mainly due to quartzite mining, justifies the preliminary classification of the new species in the Critically Endangered (CR) category using the guidelines and criteria of the IUCN Red List.

Abstract	In the present study, we describe and illustrate a remarkable new species of Syngonanthus from South America (Bolivia, Brazil and Peru). This new species is quickly distinguished from all species in the genus by trimerous and bisexual flowers, a unique set of characteristics in Syngonanthus. Complementary to this study, sequences of 33 species were downloaded from GenBank and four species had sequences newly generated for this study. Molecular phylogenetic analyses based on nuclear ribosomal ITS and the plastid regions psbA-trnH and trnL-F were performed to determine its systematic position. The results have shown S. androgynus closely related to a well-supported clade that has been treated as Syngonanthus sect. Carphocephalus. Floral traits associated with this new plant also were surveyed. Character reconstruction suggests that the bisexual flowers originated independently more than once in the genus. However, trimerous flowers appear to be an ancestral condition of the whole genus.

Abstract	—Comanthera consists of 41 species grouped in two subgenera. Both subgenera are restricted to South America and include most of the species of Eriocaulaceae used commercially as everlasting plants. Molecular and morphological phylogenies have revealed the genus and both its subgenera as monophyletic, but relationships among species have yet to be investigated. The last revision of Comanthera subg. Thysanocephalus is more than one century old, and the recognition and circumscription of taxa are still poorly understood. The present work aims, therefore, to study the taxonomy of C. subg. Thysanocephalus. Herein, descriptions of the genus and subgenus are provided along with identification keys for the subgenera and species. This taxonomic treatment proposes 17 new synonyms, excludes three taxa, and designates four lectotypes. One new species, Comanthera dimera, is described and illustrated, one variety is elevated to species status, C. angustifolia, and one species is resurrected with a new combination, C. tricostata. Nine species are accepted with no sub-specific ranks, yielding a total of 35 species in the genus Comanthera. Comments on phenology, habitat, and distribution, along with diagnoses, taxonomic notes, and distribution maps are provided.

Abstract	Five new species of Paepalanthus section Diphyomene are described and illustrated: P. brevis, P. flexuosus, P. longiciliatus, P. macer, and P. stellatus. Paepalanthus brevis, similar to P. decussus, is easily distinguished by its short reproductive axis, and pilose and mucronate leaves. Paepalanthus flexuosus, morphologically related to P. urbanianus, possesses a distinctive short and tortuous reproductive axis. Paepalanthus longiciliatus, morphologically similar to P. weddellianus, possesses long trichomes on the margins of the reproductive axis bracts, considered a diagnostic feature. Paepalanthus macer shares similarities with P. amoenus, differing by its sulfurous capitula and adpressed reproductive axis bracts. Paepalanthus stellatus also has affinity with P. decussus, but possesses unique, membranaceous, reproductive-axis bracts and a punctual inner-capitulum arrangement of pistillate flowers. Four of the described species are narrowly distributed in the state of Goiás, whereas P. brevis is endemic to Distrito Federal. All are considered critically endangered. Detailed comparisons of these species are presented in tables. Comments on phenology, distribution, habitat and etymology, along with an identification key, are provided.
