Cactaceae na Serra da Mantiqueira, Brasil

The Central Mountain Region of Espírito Santo state is located in the Atlantic Forest domain in eastern Brazil, which is the third largest center of diversity and endemism for Cactaceae. The state has 42 native species and 13 genera of this family. The aim of this study was to conduct a floristic-taxonomic study of Cactaceae in the Central Mountain Region of Espírito Santo, an area of extreme priority for conservation of Atlantic Forest biodiversity. Field trips were carried out between November 2013 and February 2016, with some additional collections and herbarium specimens were assessed. Twenty-two native species of Cactaceae were recorded for the region, which belong to the genera Coleocephalocereus (2), Epiphyllum (1), Hatiora (2), Lepismium (2), Pereskia (1), Rhipsalis (12), Schlumbergera (1) and Selenicereus (1). Of these species, 18 are epiphytes, 12 are rupicolous and 2 are climbers, some of them exhibiting more than one life-form. Two species are endemic to the state and eleven are assessed as threatened species regionally. This study contributes to improve what is known about Cactaceae in Espírito Santo state.

Vascular epiphytes represent a remarkable characteristic of the tropical cloud forests. The Serra da Mantiqueira (SM) represents one of the main highland areas of Brazil harboring vegetation remnants, and highlighting the cloud forests. We present a checklist of the vascular epiphytes found in the cloud forests of the SM, discussing the data about taxonomic representativity, distribution in the phytogeographic domains, habits, threatened status in Brazil and the states comprising the SM (Espírito Santo-ES, Minas Gerais-MG, Rio de Janeiro-RJ, São Paulo-SP). Field expeditions were performed between 2012 and 2019, as well as data gathering from scientific collections and published articles. We found 678 species, representing approximately 20% and 30% of the species found in Brazil and Atlantic forest, respectively. The richest families (Orchidaceae, 288 spp.; Bromeliaceae, 112 spp.; Polypodiaceae 65 spp.) corroborated the patterns found in different scales. Forty-one species are threatened nationally (and regionally, there are 149 in ES, 55 in MG, six in RJ, 31 in SP). These numbers of richness and threatened species highlight the relevance of directing efforts toward knowledge and conservation of both cloud forest remnants and SM as a whole, under pain of losing of a large part of the floristic diversity of Atlantic forest.
