Merostachys Spreng. (Poaceae: Bambusoideae: Bambuseae: Arthrostylidiinae) from the Atlantic Forest of Minas Gerais State, Brazil)

摘要

This work consists of a floristic survey of the Merostachys species (Bambusoideae: Arthrostylidiinae) from the Atlantic Forest of Minas Gerais State. It is based on collections of botanical material in Conservation Units and private properties, and on the analysis of specimens from national and foreign herbaria. Twenty-two taxa were cataloged. Merostachys leptophylla and M. calderoniana were recorded for the first time in the state; M. tatianae, M. espessa, M. fimbriolaminata, M. ramosa and M. ximenae are, to date, registered only for Minas Gerais. An identification key to the cataloged taxa, illustrations and comments about morphology, reproductive cycle, habitat and geographic distribution are presented.
