Talk:Woodsia

Merge

Woodsia is now the only genus in the family Woodsiaceae, so in line with WP:MONOTYPICFLORA, there should be one article here. Peter coxhead (talk) 10:28, 16 November 2019 (UTC)

Merge as per above. --Nessie (talk) 02:22, 18 November 2019 (UTC)

World Ferns has two genus in Woodsiaceae, Physematium and Woodsia. Is this a known issue? https://www.worldplants.de/world-ferns/ferns-and-lycophytes-list#g-92 MtBotany (talk) 18:03, 12 June 2023 (UTC)

@MtBotany: it is an issue, but not known to me before. We have agreed to use the Pteridophyte Phylogeny Group classification for ferns, rather than, say, Plants of the World Online (which has a much more 'lumping' approach). In PPG I (2016), Woodsiaceae has only one genus, Woodsia, with Physematium as one of the synonyms. This is what was used in 2019 to merge the articles. World Ferns uses the PPG system, but with updates. The separation of Physematium seems to date from doi:10.1002/tax.12180 in 2020; I assume that World Ferns was updated after the discussion above. I think that we should now go with World Ferns, which means we need three articles: Woodsiaceae, Woodsia and Physematium. Peter coxhead (talk) 16:49, 13 June 2023 (UTC)

@Peter coxhead Glad I noticed. I'm not an expert on ferns, I just happened to be going through all the plants that grow in Colorado. Draft:Flora of Colorado

The research causing the change appears to date from 2020. https://onlinelibrary.wiley.com/doi/10.1002/tax.12180 I don't have access to view the full paper but references in other papers through the Wikipedia library indicate that this started the new classification. So it postdates that. MtBotany (talk) 18:13, 13 June 2023 (UTC)

@MtBotany: I get full access to the 2020 paper through the Wikipedia library, so if you have a 'card' there, you should too. I've created a quick stub for Physematium. More work needed and on Woodsiaceae and Woodsia. Peter coxhead (talk) 19:06, 13 June 2023 (UTC)

@Peter coxhead Not sure why I'm not finding that paper at the Wikipedia Library. I might not have it configured correctly or something. Or maybe I need to ask for access to one of the other collections.

I'll work on moving some of the current Woodsia species to the right classification and cleaning up links. MtBotany (talk) 19:50, 13 June 2023 (UTC)
