Australian Systematic Botany

The classification and typification of all Australian ferns and lycophytes is updated to reflect the Pteridophyte Phylogeny Group I classification and the International Code of Nomenclature for algae, fungi, and plants, presenting 8 new nomenclatural combinations as well as 85 lectotypifications. The Australian fern and lycophyte flora comprises 2 classes, 14 orders, 32 families, 134 genera and 528 species and subspecies with the addition of 8 newly recorded and 6 newly recognised species since the publication of the Flora of Australia fern volume in 1998. Overall, 208 species are endemic to Australia, with Queensland having the highest species diversity and endemism by state or territory, and Lord Howe Island having the highest concentration of species and endemics per unit area. The Australian fern and lycophyte flora shows diverse links with Africa, Asia and Oceania, with the largest overlaps being shared with Asia and Oceania. More species are endemic to Australia+Oceania than to Australia+Asia. Contrasting with the classification presented in the Flora of Australia, no genera of ferns and lycophytes are now considered to be wholly endemic to Australia.
