@martinbishop, while I think this change is in accordance with our policies since the majority of the authorities we follow use this treatment, please remember to cite your sources. In this case, I would have listed The Plant List as a source, and further provided links in the description to the various authories they follow and how they treat this change, e.g. Calflora continues to use Chenopodiaceae, but TPL, GoBotany, and New Zealand Plants all consider it synonymous with Amaranthaceae. This is a pretty big change that has affected a lot of people, so it's important to provide as much clarity as possible so people can see what happened and why.

Yes, the references could include TPL
http://www.theplantlist.org/1.1/browse/A/Amaranthaceae/
and the paper of the molecular evidence published in 2003

and the latest update of APG IV

Unfortunately, I did make a mistake as the Chenopodiaceae should be included in a wider Amaranthaceae and I am unsure how to do this successfully.
If someone knows how to fix it I would be grateful.

I think you did it correctly, but there was some kind of bug in which all the children of Chenopodiaceae didn't get moved over to Amaranthaceae. I'm looking into that.

Posted by kueda over 8 years ago

Do you know if everything in Chenopodiaceae is now in the subfamily Chenopodioideae?

Posted by kueda over 8 years ago

No, it is not the case.
Stevens gives (incomplete list) http://www.mobot.org/MOBOT/research/APweb/welcome.html
Chenopodioideae Burnett
(Cuticle waxes 0); pericarp usu. thin, evascularized; testa tanniniferous, exotesta much enlarged, with tannin stalactites (0); x = (8) 9.
10/500: Atriplex (300), Chenopodium (150), Dysphania (40).

This article gives more details but I am not sure how accurate it is
https://en.wikipedia.org/wiki/Amaranthaceae and
https://en.wikipedia.org/wiki/Chenopodioideae

Posted by martinbishop over 8 years ago

Ok, I moved all the former children of Chenopodiaceae over to Amaranthaceae, so I think that should fix everything. Let me know if you're still seeing any problems.

Thank you very much for sorting this out.
