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.
大量集中在巴西米纳斯吉拉斯州的刺叶树科物种，构成了南美洲大部分耐旱植物区系。在禾本科植物中，两种微穗草属植物和穗三毛是耐旱的。虽然分布广泛，但它们生长低矮，看起来并不重要。除了紫萁属植物外，干旱地区的耐旱蕨类植物与北美报道的“复苏”蕨类植物区系有关。雨林地区附生蕨类植物耐旱植物区系的可能性尚未得到研究。
