Chusquea
Chusquea is a genus of evergreen bamboos in the grass family. Most of them are native to mountain habitats in Latin America, from Mexico to southern Chile and Argentina.
They are sometimes referred to as South American mountain bamboos. Unlike most other grasses, the stems of these species are solid, not hollow. Some animals are, to various extents, associated with stands of Chusquea, for example the Inca wren and the plushcap.
