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).

Raso da Catarina is one of the eight Ecoregions recognized for the Caatinga biome. This work includes the taxonomic study of Boraginales Juss. . The species most commonly found were Cordia glabrata, Varronia globosa, V. leucocephala, Euploca procumbens, Heliotropium angiospermum and H. elongatum, associated with sandy soils. Cordia superba and C. trichotoma were found in moist environments, higher altitudes, clay or sandy-clayey soils. Euploca paradoxa was collected on the banks of the São Francisco River, and Varronia leucomalloides occurs in the hiperxerophytic Caatinga associated with rocky or sandy soils and in areas of contact between Caatinga and Cerrado, these species were more restricted in the area. Comments are made on the morphology and taxonomy, illustrations, and data on geographical distribution and phenology, besides a key for the taxa studied. . As espécies mais comumente encontradas foram Cordia glabrata, Varronia globosa, V. leucocephala, Euploca procumbens, Heliotropium angiospermum e H. elongatum, associadas aos solos arenosos. Cordia superba e C. trichotoma encontradas em ambientes mais úmidos, sobre altitudes mais elevadas, solos argilosos ou areno-argilosos. Euploca paradoxa coletada nas margens do rio São Francisco e, Varronia leucomalloides ocorrendo em Caatinga hiper-xeró fita, associada a solos pedregosos ou arenosos, e em áreas de contato entre Caatinga e Cerrado, foram às espécies mais restritas na área. São apresentados comentários sobre morfologia e taxonomia, ilustrac¸õ es, e dados sobre distribuic¸ão geográfica e fenologia, além de uma chave para os táxons estudados.

Resumo AbstractThe family Heliotropiaceae has more than 450 species, mainly distributed in the tropics and subtropics. In Brazil, it is represented by the genera Euploca Nutt., Heliotropium L., Myriopus Small and Tournefortia L. The aim of this study was to describe the leaf anatomy of six species of Heliotropiaceae recorded in the semiarid region of Brazil: E. polyphylla the Caatinga (Brazilian savannah), we also sought to determine and highlight the anatomical features adaptive to the region and to identify features with potential diagnostic value. Leaf structures were analyzed by light microscopy and scanning electron microscopy. Additional tests were also carried out to detect starch and total lipids. The morphological variation and the distribution of trichomes were the most relevant features for species diagnosis. The distribution of stomata in M. salzmannii and H. angiospermum differed from that described in other papers, which demonstrates the anatomical plasticity of these species. This is the irst report describing the leaf blade of M. rubicundus.
