Brief SummaryRead full entry
This clade represents Angiopteris in a broad sense, including Archangiopteris, Macroglossum and Protomarattia.
Angiopteris is a genus of perhaps 100 species, occurring from Madagascar to the Pacific islands, and from India and southern Japan to northern Australia.
The taxonomy of the genus Angiopteris is contentious, and species numbers have fluctuated immensely. Mabberley (1997) considered the genus to consist of 200 poorly defined microspecies; Rolleri (2002, 2003) reviewed the genus, dealing with a total of only ten species. It is evident that additional studies are needed to resolve these taxonomic problems and better define the species morphologically and genetically.
Species of Angiopteris are used in the Pacific to perfume coconut oil, and in India the starch from the rhizome is eaten and used to brew an intoxicating drink (Mabberley 1997). Angiopteris evecta is documented as naturalised in Hawaii, Jamaica and Costa Rica (Christenhusz & Toivonen, 2008).
