Hemidictyaceae is a family of ferns in the order Polypodiales.[1] Its sole genus is Hemidictyum C.Presl 1836, commonly known as the marginated half net fern.[2] Hemidictyaceae is considered to be a sister family to Aspleniaceae, believed to have diverged during the Cretaceous period.[3][4]
The name Hemidictyum was derived from the terms hemi (half) and diktyon (net), from the veins being netted only half-way across the pinnules.[5]
Distribution
Hemidictyum is a native neotropical fern, found in Mexico, the Caribbean, Costa Rica, Guatemala, Honduras, Nicaragua, Panama, French Guiana, Suriname, Brazil, Venezuela, Puerto Rico, Bolivia, Colombia, Ecuador, and Peru.[2][6]
Species
There is currently only one accepted Hemidictyum species name, Hemidictyum marginatum. The other names are considered to be synonyms, either of that species, or of accepted Asplenium species:[7]
- Hemidictyum marginatum (L.) C.Presl 1836
- Hemidictyum purdieanum (Hook.) T.Moore 1857
- Hemidictyum finlaysonianum (Wall. ex Hook) T.Moore 1857
Phylogenic relationships
The following diagram for the eupolypods II, based on Lehtonen, 2011,[8] and Rothfels & al., 2012,[9] shows a likely phylogenic relationship between the Hemidictyaceae and the other families of the eupolypods II clade.
