Map[edit]
I'm concerned that the map does not, as claimed, show the "native range" of the species, but the countries in which it occurs. The difference my be insignificant, in which case a change of caption will suffice, or it may be significant, in which case the map is misleading (it will certainly be so if the same is done for other species, with very localised distributions).

- Pigsonthewing, thanks, the species distribution data is taken from POWO which is the agreed best source for plant distribution data by Wikiproject Plants. I think this just needs some finessing of the labelling, POWO simply describes the areas where it is native, I'm not sure if there is another source that describes better that this means it is not neccissarily found across the whole of each country. Any suggestions for clearer wording? John Cummings (talk) 13:01, 30 June 2023 (UTC)
- Where do say that? The same source ([1]) shows the distribution for Coincya wrightii as including all of England, all of Scotland, including each of its islands, and all of wales, as well as the Isle of Man. In fact it only occurs on the tiny isle of Lundy. The only suitable captions would be along the lines of "Countries where Foo bar occurs". The phrases "distribution" or "native range" should not be used. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 13:15, 30 June 2023 (UTC)
- Pigsonthewing, sorry I missed this before, the index of different locations is defined by https://www.tdwg.org/standards/wgsrpd/ which is some kind of international committee of plant experts from different research institutes and from what I understand is the international standard. Agreed for your example it isn't granular enough. I'm asking on Wikiproject Plants for some information on what the rules are about plant distribution sources and if there is already a disclaimer written for saying 'this map might not be granular enough' or something. I wonder how common 'this plant lives on one tiny island next to another island' examples will be. There's maybe something clever you could do with flagging endemic species to double check them or something. I'll wait to hear back from the plant experts before doing much else.
