Hemidictyum is a genus of ferns with a single species, Hemidictyum marginatum, commonly known as the marginated half net fern. [3] In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it is the only genus in the family Hemidictyaceae. [4] Alternatively, the family, along with Aspleniaceae sensu stricto, may be placed in a much more broadly defined family Aspleniaceae as the subfamily Asplenioideae. [5]
Taxonomy
The name Hemidictyum was derived from the terms hemi (half) and diktyon (net), from the veins being netted only half-way across the pinnules. [6]
Phylogenetic relationships
Hemidictyaceae is considered to be a sister family to Aspleniaceae s.l., believed to have diverged during the Cretaceous period. [7] [8] The following cladogram for the suborder Aspleniineae (as eupolypods II), based on Lehtonen (2011), [9] and Rothfels & al. (2012), [10] shows a likely phylogenetic relationship between the Hemidictyaceae and the other families of the clade.
| Aspleniineae (eupolypods II) | |
Species
There is currently only one accepted Hemidictyum species, Hemidictyum marginatum. [2]
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. [3] [11]
