“…Em Minas Gerais, a maior concentração de tratamentos para as Cactaceae está localizada na Cadeia do Espinhaço (Zappi 1990;Taylor & Zappi 1991;Zappi & Taylor 2003;Taylor & Zappi 2004;Zappi & Taylor 2008). Em contrapartida, apenas um estudo específico foi realizado na região da Zona da Mata, na Serra Negra, município de Rio Preto (Gonzaga et al 2014).…”

-(Cactaceae in the Parque Estadual do Ibitipoca, Minas Gerais, Brazil). The Parque Estadual do Ibitipoca (PEIB) is located in southeastern Minas Gerais, between the municipalites of Lima Duarte, Santa Rita de Ibitipoca and Bias Fortes (21º40'-21º44'S and 43º52'-43º55'W). The park has an area of 1.488 ha, with altitudes between 1.100 to 1.784 m.s.m., and the predominant vegetation is the campo rupestre. The aim of the present study was to conduct a survey of Cactaceae in PEIB. The family comprises four genera and seven species, as follows: Arthrocereus melanurus subsp. magnus, Hatiora salicornioides, Rhipsalis elliptica, Rhipsalis floccosa subsp. pulvinigera, R. juengeri, R. pulchra and Schlumbergera opuntioides. Identification keys, descriptions, illustrations, taxonomic and ecologic comments are provided for the species treated.

Field work and data from herbaria collections (2686 records) representing 283 taxa (265 species and 18 infraspeciWc taxa) of Bromeliaceae occurring at Minas Gerais state, southeastern Brazil, were analyzed in order to obtain distribution and diversity information, and to determine IUCN (The World Conservation Union) conservation status for each taxon. A map containing 1°£ 1° grid cells was used to identify priority areas for new research collections, areas of high species diversity, and Bromeliaceae conservation status. A clear decrease in Bromeliaceae diversity is observed between the eastern and the western portions of Minas Gerais, and low Xoristic similarities were found between neighboring grid cells. The rocky mountains of Cadeia do Espinhaço are considered the most important area for Bromeliaceae endemics. From the 283 taxa of Bromeliaceae that occur at Minas Gerais, 118 (42%) are considered threatened, and 124 taxa (44% of the total) do not occur inside any protected area. The region of the Quadrilátero Ferrífero in the southern portion of the Cadeia do Espinhaço is the most threatened, and urgent strategies for conservation of this rich Bromeliaceae Xora are needed. Northeastern Minas Gerais, particularly the rocky outcrops or inselbergs located in the Jequitinhonha and Mucuri rivers drainage basins need additional collection eVorts and conservation actions focused on these saxicolous taxa.
