摘要：

The 13 high altitude/latitude, dwarf species of Chusquea in Brazil are described, illustrated, and mapped, and their morphology, habitats, distributions, and taxonomic affinities are discussed. Two keys to species are provided, one based solely on vegetative characters, and the other on vegetative and flowering characters. Chusquea erecta, C. nutans, C. riosaltensis, C. windischii, C. caparaoensis, and C. nudiramea are described as new, and C. microphylla is elevated to specific status. Two subspecies are recognized within the variable C. mimosa: C. mimosa subsp. australis and subsp. mimosa. Seven species are formally classified within Chusquea sect. Swallenochloa; the remaining six species are classified into two informal categories, the Nudiramea and Heterophylla groups. A list of all the species currently included within Chusquea sect. Swallenochloa is provided.
