Abstract Asteraceae is highly diverse in the Atlantic Forest, especially in montane environments. The early-diverging tribes within Asteraceae are of particular interest because of their great representation in Brazil and unique features within the family. Thus, a floristic inventory and systematic treatment of these basal grade in Caparaó National Park, an important remnant of Atlantic Forest that has been highlighted for its diversity and endemism, were undertaken. The study was conducted by examining specimens from representative collections of Caparaó and a field expedition. A total of 15 species were found, representing six genera and four tribes, with Mutisieae and Nassauvieae being the most representatives. Six of the species have restricted distributions, either to Brazil (3 spp.), the Atlantic Forest (2) or Caparaó mountain (Mutisia lutzii). Three new records were documented for the park, namely Chaptalia integerrima, Moquiniastrum polymorphum and Mutisia coccinea. Floristic inventories and systematic treatments can make great contributions to science by bringing a better understanding our biodiversity and providing relevant information about flora for the conservation of priority areas. environments earlydiverging early diverging family Thus Park endemism undertaken expedition 1 found representatives distributions 3 ( spp., spp spp. , spp.) 2 (2 lutzii. lutzii . lutzii) park integerrima coccinea areas

Resumo Um inventário florístico e um tratamento taxonômico de Asteraceae da Serra da Confusão do Rio Preto no estado de Goiás são apresentados. As coletadas foram realizadas entre julho de 2017 a dezembro de 2018 em um fragmento de cerrado sentido restrito com transição para cerrado rupestre, totalizando 38 expedições abrangendo todas as estações do ano. O tratamento taxonômico dos espécimes resultantes inclui chaves de identificação, diagnoses e descrições, status de conservação, endemismo e material examinado. Ao todo 59 espécies foram encontradas, pertencendo a 32 gêneros e 10 tribos. Os gêneros predominantes foram Lessingianthus (8 spp.) e Chromolaena (5 spp.) enquanto as tribos predominantes foram Vernonieae (19 spp.), Eupatorieae (13 spp.) e Heliantheae (7 spp.). O padrão de riqueza para as tribos foi o mesmo registrado em outros inventários florísticos para o domínio Cerrado, especialmente o cerrado sentido restrito. Vinte e uma espécies (35.6%) são restritas ao Brasil e apenas Isostigma resupinatum é restrito ao estado de Goiás.

Abstract A floristic inventory and a taxonomic treatment of Asteraceae from Serra da Confusão do Rio Preto in the state of Goiás are provided. Collections were carried out from July 2017 to December 2018 in a fragment of cerrado sensu stricto with transition to cerrado rupestre (rocky cerrado), for a total of 38 expeditions covering all seasons. Taxonomic treatment of the resulting specimens includes identification keys, diagnoses and descriptions, conservation status, endemism and examined material. A total of 59 species were found, belonging to 32 genera and 10 tribes. The predominant genera were Lessingianthus (8 spp.) and Chromolaena (5 spp.) while the predominant tribes were Vernonieae (19 spp.), Eupatorieae (13 spp.) and Heliantheae (7 spp.). The richness pattern for tribes was the same as recorded in other floristic inventories in the Cerrado domain, especially cerrado sensu stricto. Twenty-one of the species (35.6%) are restricted to Brazil while only Isostigma resupinatum is restricted to the state of Goiás. Conyza primulifolia, Lepidaploa cuiabensis and Lepidaploa sororia were new occurrences for the state. provided 201 rocky cerrado, , cerrado) 3 seasons keys descriptions status material 5 found 1 8 ( spp. spp 19 (1 spp., 13 7 spp.. . domain Twentyone Twenty one 35.6% 356 35 6 (35.6% primulifolia 20 35.6 (35.6 2 35.
