Bambusoideae (Poaceae) in the Serra do Brigadeiro State Park, Minas Gerais, Brazil

Abstract This study consists of a floristic survey of the Bambusoideae (Poaceae) species that occur in the Serra do Brigadeiro State Park (PESB). The study area is inserted in the Atlantic Forest, considered as one of the centers of bamboo endemism. We carried out expeditions from August 2013 to July 2015 for the collection of botanical material and observation of the species in their natural environment. In addition, the collections of the herbaria BHCB, CESJ, HUEFS, ISC, K, MG, RB, SPF, VIC, and VIES were analyzed. Six genera and 27 species were recorded in the PESB. The most diverse genus is Chusquea with 16 species, followed by Merostachys and Aulonemia with four species each, and Colanthelia, Guadua, and Parodiolyra with one species each. Identification keys for genera and species, descriptions, and morphological comments are presented. PESB has the highest bamboo species richness recorded for the conservation units of Minas Gerais.
