Additionally, the species is often associated to the lowland forests, with only one record from Colombian mountains.…”

We present the first voucher-based record of Pouteria macrocarpa for Brazilian Atlantic forest and extend the occurrence area of it. Besides, a brief taxonomic description, an identification key for lignified-fruits Pouteria species, and information about phenology and herbarium records are provided. According to the IUCN Red List and the Red Book of the Brazilian Flora, the species is considered Vulnerable (VU). However, facing the new available data, we believe it should be reassessed as Endangered (EN). Key words: Brazil, Chrysophylloideae, Ericales, Espírito Santo, Neotropics. ResumoEste é primeiro registro baseado em vouchers de Pouteria macrocarpa para a Mata Atlântica e informações sobre novas áreas de ocorrência da espécie são disponibilizadas. Além disso, são apresentadas uma breve descrição taxonômica, uma chave de identificação de espécies morfologicamente afins e informações fenológicas e das coleções botânicas. De acordo com a Lista Vermelha da IUCN e do Livro Vermelho da Flora Brasileira, a espécie é considerada Vulnerável (VU), no entanto, após re-análise dos dados aqui apresentados, P. macrocarpa deve ser recategorizada como Em Perigo (EN).

“…The Brazilian Amaranthaceae list (Table 1) was based on the research by the Brazilian taxonomists Marchioretto [15][16][17][18][19][20][21] and Siqueira [22][23][24][25] and on the most important taxonomic references to this Family both from the literature ( Table 2) and Brazilian Herbaria (Table 3). All cited Herbaria are listed according to the Index Herbariorum [26,27].…”

“…Different species can be very alike in habit and vegetative morphology. The correct identification depends almost exclusively on some flower details, whose small dimensions make it especially difficult to work in the field, demanding a highly specialized work, only partially carried out for this family (15)(16)(17)(18)(19)(20)(21)(22).…”

“…O risco de extinção na natureza é alto e pode ocorrer a médio prazo (categoria "vulnerável" -VU) para a maior parte das espécies, mas é muito alto e pode ocorrer num futuro próximo (categoria "em perigo" -EN) para Inga sellowiana Benth. (Marchioretto et al 2005). Também é importante ressaltar que três das sete espécies ameaçadas não foram registradas na RFMG, o que aumenta o valor dos fragmentos onde essas espécies estão presentes para a conservação.…”

. The objective of this research was to evaluate the conservation status and the importance of forest remnants at Embu (SP, Brazil) for the maintenance of the local plant diversity. A previous classification of the vegetation cover was made with aerial photographs interpretation in order to guide the selection of the forest fragments to be evaluated. In a quick survey, the floristic composition (focused on tree species) and some structural and physiognomic descriptors were recorded to assess the conservation status of the vegetation. Nine remaining forests with areas between four and 35 ha were characterized, totaling 140 ha. Despite of the short time, 197 species were recorded, being 172 trees typical of the Ombrophilous Dense Forest and some species from the Seasonal Semideciduous Forest. Comparing the tree and shrub species between the remaining forests and the Morro Grande Reserve Forest -conservation unit located next to the study site -95 species were found in common and 65 species exclusively occurring at Embu forests. Moreover, seven threatened species according to the state, national and world red lists were recorded. Although these seven species were mostly found in the more mature fragments, some were also found in disturbed ones, indicating that even with the massive occurrence of secondary forests, the maintenance of the forest remnants of Embu may help to preserve some species still not protected in the region. The forest can also contribute to protect water and soil resources and to connect native forest patches, facilitating the gene flow of plant and animal species and, consequently, promoting the maintenance of the Atlantic Forest biodiversity.Keywords: Atlantic Rain forest, tree community, biodiversity. O objetivo deste trabalho foi avaliar o grau de conservação e a importância dos remanescentes florestais situados em Embu -SP para a manutenção da diversidade da flora local. Para tanto, realizou-se o mapeamento e a classificação prévia da cobertura vegetal da área, a fim de se selecionarem os fragmentos a serem avaliados. Para determinar o grau de conservação desses fragmentos, efetuou-se levantamento expedito, com ênfase na vegetação arbórea, no qual foram registrados a composição florística e alguns descritores fisionômicos e estruturais. Foram caracterizados nove fragmentos, cujas áreas variaram de aproximadamente quatro a 35 ha, totalizando 140 ha. Apesar de curto, o levantamento possibilitou o registro de 197 espécies, das quais 172 arbóreas e em sua maioria da Floresta Ombrófila Densa mas com algumas espécies da Floresta Estacional Semidecidual. Comparando a composição de espécies arbóreas encontradas nos fragmentos àquela presente na Reserva Florestal do Morro Grande -unidade de conservação localizada próxima à área de estudo -constatou-se a ocorrência de 95 espécies em comum às duas áreas e 65 espécies com ocorrência exclusiva nos fragmentos. Além disso, foram registradas
