Global sustainability rests on a myriad of benefits provided by natural ecosystems that support human livelihoods and well-being, from biodiversity persistence to climate regulation. The undeniable importance conserving tropical forests has drawn most the conservation spotlight towards it. However, open such as Brazilian Campo Rupestre (rupestrian grassland), have been historically overlooked despite their high diversity key associated ecosystem services. We highlight major current threats...
We describe and illustrate two new species, Actinocephalus delicatus A. giuliettiae (Eriocaulaceae, Paepalanthoideae), from the Espinhaço Range in Minas Gerais, Brazil, compare them with morphologically most similar species. Diagnostic characters, morphological variation, geographic distribution, habitat conservation status, as well line drawings, photos a distribution map are provided for both
Abstract Comanthera and Syngonanthus (Eriocaulaceae) are monocotyledonous herbs that occur mainly in neotropical savannas the Guiana Shield southeastern Brazil, with a few species Africa. Phylogenetic relationships still unresolved have not yet been assessed using broad comprehensive sampling. The present study aimed to test monophyly of both genera their putative infrageneric taxa evaluate taxonomy supporting synapomorphies light resolved phylogeny. resulting phylogenetic hypotheses were...
Paepalanthus subgenus Xeractis (Eriocaulaceae) comprises 28 recognized species endemic to the Espinhaço Range, in Minas Gerais state, Brazil. Most of are restricted small localities and critically endangered, but still need systematic study. The monophyly has already been tested, only with a few species. Our study presents first phylogenetic hypothesis within group, based on morphology. A maximum parsimony analysis was conducted matrix 30 characters for terminal taxa, including all two...
Abstract We report the rediscovery of seven Eriocaulaceae taxa, which were known exclusively from type collection or historic collections. The taxa are Actinocephalus cipoensis , coutoensis ithyphyllus Paepalanthus argenteus var. elatus decussus stuetzelii and Syngonanthus circinnatus all narrowly distributed. They occur in southern central part Espinhaço Range Minas Gerais, Brazil. provide a brief taxonomic comment for each taxon, as well details about populations, habitat, revised IUCN...
The Espinhaço Range in Brazil is one of the richest regions world plant species. It also main center diversity and endemism many taxa, including Paepalanthus. This genus second largest Eriocaulaceae, third Brazilian flora. work aims to survey Paepalanthus richness Central Minas Gerais. A checklist 116 species two varieties presented here, with data comments about richness, endemism, conservation, together a new synonym for bonsai combination Actinocephalus, both endemic Among recorded...
Comanthera consists of 41 species grouped in two subgenera. Both subgenera are restricted to South America and include most the Eriocaulaceae used commercially as everlasting plants. Molecular morphological phylogenies have revealed genus both its monophyletic, but relationships among yet be investigated. The last revision subg. Thysanocephalus is more than one century old, recognition circumscription taxa still poorly understood. present work aims, therefore, study taxonomy C....
Abstract We here evaluate the conflicting recent splitter and lumper strategies concerning generic classification system of Eriocaulaceae, whether Paepalanthus s.str. its proposed segregate genera are morphologically recognizable. To this end, we examine evidence from inflorescence branching patterns, seed coat, phylogeny in detail, contrast circumscriptions with available data. also indicate possible consequences for herbarium curators, keepers users large databases, generalist...
Three new species of Paepalanthus Mart. sect. Diphyomene Ruhland (Eriocaulaceae) from Minas Gerais (Brazil) are described and illustrated. arcuatus Trovó, defined by its curved leaves, is known only the Serra do Cipó National Park shares morphological characters with P. decussus Körn. linearis linear exclusively Itacambira resembles polycladus Silveira. sericiscapus sericeous scapes, type specimens collected in da Canastra arcuatus. All their localities assigned a preliminary conservation...
We describe and illustrate Paepalanthus sphaeroides (Eriocaulaceae, Paepalanthoideae) from the Mantiqueira Range in South-eastern Brazil compare it with morphologically most similar species: aequalis eriophaeus.Paepalanthus has unique membranaceous sheaths tightly adpressed to scapes, patent involucral bracts slightly surpassing capitula, sepals of staminate flowers fused base middle as distinctive characteristics.Comments on morphological variation, geographical distribution, ecology,...
Paepalanthus Mart. sect. Diphyomene Ruhland (Eriocaulaceae) is mainly diversified in the savannas of Central Brazil (Cerrado). This an unusual pattern regarding highest diversity Eriocaulaceae Southeastern (in Espinhaço Range). Despite this interesting contrast, geographic distribution these species has yet to be explored. The present work aims detail order discuss biogeographical patterns. are also categorized according their risk extinction, based on IUCN criteria, establishing...
We describe and illustrate Paepalanthusserpens, a microendemic species of Eriocaulaceae from the Espinhaço Range. The is known single population growing in rocky areas Serra do Cipó, Minas Gerais. It placed Paepalanthusser.Paepalanthus, easily distinguished its congeneric by elongated, lignescent stem, thickened marcescent sheaths linear leaves, which are arranged rosette at stem apex, scapes equalling leaf height, capitulae with straw-coloured involucral bracts. Comparisons morphologically...
The diversity of Eriocaulaceae in the Neotropics is primarily concentrated Espinhaço Range Brazil and Tepuis Venezuela. Species richness outside these areas, however, significant but poorly known. Based on improved taxonomic knowledge about Atlantic Forest domain Brazil, we propose nomenclatural changes, provide an identification key annotated list species core Serra da Mantiqueira. A total 24 were found, one described quite recently two still known only from type specimens. Lectotypes for...
We describe and illustrate three new species of Paepalanthus (Eriocaulaceae: Paepalanthoideae) from the Espinhaço Range: P. argyrotrychus, farinaceus velutiphyllus, all endemic to Serra do Ambrósio, a mountain disjunct Range in municipality Rio Vermelho, Minas Gerais, Brazil. These belong ser. (=Paepalanthus [unranked] Variabiles). provide detailed descriptions illustrations for each taxon, as well comments on habitat, distribution, morphology, conservation their affinities most...
The Chapada dos Veadeiros National Park is a conservation unit established to preserve the highest savannahs of Central Brazil and their unique biodiversity. Eriocaulaceae are relevant conspicuous family in such high savannahs, but its diversity poorly known, documented solely general lists or isolated efforts aimed at small groups. After structured series field expeditions analysis specimens from herbaria, we provide nomenclatural novelties, first identification key, an illustrated...
Paepalanthus balansae, P. lundii, and scholiophyllus are morphologically related species growing in swampy areas of central South America, frequently misidentified collections worldwide. We discuss here new relevant morphological data to elucidate the circumscription these species. balansae is maintained as a distinct following its current circumscription, while wide variation understood within broader lundii concept treated synonymous. report herein presence short lateral branches covered...
Crepidomanes minutum (Hymenophyllaceae) is here identified and recorded from Mauritius for the first time. The Mauritian specimens, in addition to those of La Réunion observed at low middle elevations, are easily distinguished populations outside Mascarene Archipelago by their dwarfed size rarity stipe proliferation that usually characterizes this species. We thus describe a new variety species Islands.
Syngonanthus weddellii var. gracilis Moldenke (1973) was described very briefly based on a single collection. A careful analysis reveals that this variety has dimerous flowers, free petals of the pistillate flower and bifid stigmatic branches. It is therefore misplaced in Ruhland (1900). We transfer it to Paepalanthus Mart. (1834) at species level, as distinct from morphologically similar species: flaccidus (Bong.) Koern. (1863), trichophyllus strictus (1863). The epithet no longer...
Abstract The Serra do Caraça, located in Minas Gerais state, Brazil, hosts a remarkable biological diversity, comprising rare and endemic plant species. Several naturalists have visited the area since XIX century made important botanical collections, many of these established as type specimens to describe different taxa, including Eriocaulaceae (Poales) species varieties. This work provides floristic treatment from presenting descriptions, distribution map, photographs, identification key,...
