Alsophila firma, commonly known as the maquique fern (Spanish: helecho maquique, Nahuatl languages: peshma), is a deciduous tree fern in the family Cyatheaceae endemic to Mexico, other countries of Central America, Colombia, and Ecuador. In the cloud forests of Mexico, it is considered an emblematic species and serves as a host for native epiphytic plants. However, habitat destruction and overconsumption of the trunks for handicraft production have threatened populations in Mexico. As a result, Alsophila firma is considered threatened in the state of Veracruz and has been given special protection per Mexican law.
