Numerous Velloziaceae species concentrated in Minas Gerais, Brazil, constitute most of the desiccation tolerant flora of S. America. In the grasses, two Microchloa spp and Tripogon spicatus are desiccation tolerant. Though widespread, they are low growing and appear unimportant. With the exception of Anemia, desiccation tolerant ferns in dry land areas are related to the “resurrection” fern flora reported for N. America. The likely possibility of a desiccation tolerant flora of epiphytic ferns in rain forest areas was not investigated.
