Davalliaceae, family Davalliaceae(noun)
one of a number of families into which Polypodiaceae has been subdivided in some classification systems
Davalliaceae is a family of ferns in the order Polypodiales. It is sister to the largest family of ferns, Polypodiaceae, and shares some morphological characters with it. Davalliaceae is native to tropical and subtropical regions of the Pacific, Australia, Asia, and Africa. They are small to medium in size. In the wild, they are usually epiphytic, sometimes epipetric or terrestrial. Many species of Davallia are in cultivation, with Davallia tyermanii, Davallia fejeensis, and Davallia solida being perhaps the most well-known. A key to the cultivated species of Davallia is available. Davallodes, Humata, and Wibelia have species in cultivation as well. In Davalliaceae, many of the species are closely related and hard to distinguish from each other. In 1990, a treatment of Davalliaceae estimated the number of species at 110. A 2008 paper listed all of the species, recognizing only 63. A new species, Davallia napoensis was described in 2011.
