Vittaria is a genus of ferns in the family Pteridaceae. It had previously been placed in the family Vittariaceae,[1] but that family is no longer recognized.[2]

Vittaria consists of epiphytes, with simple, entire, narrowly linear fronds.[3] It comprises six species, five of which are native to the neotropics. Vittaria isoetifolia is native to tropical Africa and islands of the southwestern Indian Ocean.[4] Vittaria isoetifolia and Vittaria lineata are known, albeit rarely, in cultivation.[5]

Vittaria was named by James Edward Smith in 1793 [6] in Mémoires de l'Académie Royale des Sciences (Turin).[7] The generic name is derived from the Latin, vitta, meaning "a band or ribbon".[8]

In 1990, Vittaria was defined broadly and estimated to have between 50 and 80 species.[1] The genus is difficult to divide into species, and many of the species are only doubtfully distinct. In a 1997 revision of the vittarioid ferns, only 34 species were recognized in Vittaria sensu lato.[4] Twenty of these were transferred to Haplopteris and eight to Radiovittaria, leaving only six in Vittaria.[4]

The first well-sampled molecular phylogenetic study of the vittarioids was based on the chloroplast gene rbcL.[9] In this study, it was found that the type species of Monogramma is embedded in Haplopteris. Because Monogramma is the older name, unless Haplopteris is split, all of the species of Haplopteris will eventually be transferred to Monogramma.

Species

Vittaria includes the following species (but this list may be incomplete).
