Oleandraceae Ching ex Pic.Serm.
The Oleandraceae Family was named and described by Ren Chang Ching and Rodolfo Emilio Giuseppe Pichi Sermolli in Webbia 1965.
Plants of the World Online lists four accepted genera in this family of ferns. There isn’t much information about this family so far but maybe there will be more later since Plants of the World Online is still uploading data.
Accepted genera include:
Arthropteris-The Wikipedia article says this genus is currently in the family Tectariaceae. When I do a search on Plants of the World Online for that family, it brings up the family Dryopteridaceae which is also an accepted family of ferns which does not list this genus. Interesting, the Wikipedia article also says this genus was “formerly” placed in the families Oleandraceae “OR” Davalliaceae. Strange. What does it mean “formerly” and “OR”?
Nephrolepis-Of course we all know what a Boston Fern. The correct species name is Nephrolepis exalta but it is still marketed under the name Neanthe bella. The Wikipedia article about this genus proudly says it is “in the family Nephrolepidaceae (or Dryopteridaceae in some classifications).” It also states there are about 30 species in this genus. Again it lists the incorrect family and “OR”.
Oleandra-Apparently, there may be only one species of this fern, Oleandra hainanensis and the Wikipedia lists it in the current family but that’s it…
Psammiosorus-only one species of this one, too, and without any information to speak of…
The 2013 version of The Plant List (no longer maintained) lists the genus Oleandra as the only accepted genus in this family. It lists 3 unresolved genera, Lepidonevron (now a synonym of Nephrolepis), Neuronia (now a synonym of Oleandra), and Ophiopteris (also now a synonym of Oleandra).
I am going to have to keep an eye on this family because I think more changes are ahead.
