choess | Australian tree fern (Cyathea cooperi) |
appears to be a taxonomic synonym of Sphaeropteris cooperi |
Oct. 18, 2018 22:23:19 +0000 | choess |
changed committed--compatible with POWO and PPG I |
Generally accepted as Cyathea cooperi here in Australia (currently, anyway). Only Florabase, the WA online flora uses Sphaeropteris cooperi

This is a widespread weed globally, a nasty invasive, and is phylogenetically resolved in Sphaeropteris, so it seems problematic to treat it in Cyathea in the context of a global taxonomy.
Here is the most recent classification of Australian Ferns and Lycophytes (Field 2020)

It is a hugely problematic invasive species in Hawaii:

Flora of California also treats it as Sphaeropteris:

agree with @susanfawcett, this taxon should be treated according to POWO, as proposed by @franzanth.
Draft for taxon swap:

@susanfawcett @franzanth @kitty12 does that look alright?
I'd run this by @choess
My inclination would also be to remove the genus Cnemidaria (syn. Cyathea). The jury is out on Gymnosphaera (syn. Alsophila according to PPG I), but will soon be revisited by PPG II. Sphaeropteris cooperi really shouldn't be recognized in Cyathea unless all Cyatheaceae are treated in a single genus.
Queensland herbarium, Australia, also uses Sphaeropteris cooperi
Census of the Queensland Flora and Fungi 2022 https://www.data.qld.gov.au/dataset/census-of-the-queensland-flora-and-fungi-2022 (see link to Full data set which is searchable using an online form)
The taxon swap page has been there stagnant for almost a year now. I'm all for it. Our main vascular plant database (https://acores.flora-on.pt/#/1sphaeropteris) also uses Sphaeropteris, and because INat uses Cyathea my observations can't get imported to there.
@j_orfao as an aside from the swap, how come that database doesn't have synonym matching set up?
@thebeachcomber It does have it, but only for certain species. I suppose the coordinator of the database either has problems including the synonyms or he just simply forgot to add them. I might have to message him about that.
This is a synonym of Sphaeropteris cooperi (Hook. ex F.Muell.) R.M.Tryon
