New Argentinian Pyrrhocactus?
Re: New Argentinian Pyrrhocactus?
Thank you for the link Dave, very good looking cactus.
Re: New Argentinian Pyrrhocactus?
It is indeed an interesting looking plant.
I was able to buy some seeds labeled as Neowerdermannia lichyana from Kaktusy Cacti Growers Club Hradec Králové (www.kaktusyhk.cz) with fieldnumber VS1388 this winter. Will sow it next month. I assume it is the same plant.

Re: New Argentinian Pyrrhocactus?
Fascinating plant. I do like the cryptic species! Thanks for sharing Dave.
Re: New Argentinian Pyrrhocactus?
Very interesting plant and description!
I have never heard of there being a correlation between Pyrrhocactus and Neowerdermannia before though.
Have I missed something there?

With apologies to the late Professor C. D. Darlington the following misquotation springs to

Re: New Argentinian Pyrrhocactus?
I think the authors were referring to morphological similarities and the fact that this new species was first tentatively named as Neowerdermannia lichyana (https://cactus-moravia.eu/uncategorized ... of-cactus/).
Genetically, Eriosyce (including Pyrrhocactus) forms a monophyletic clade that is sister with a clade that includes Parodia, Neowerdermannia, Rimacactus, and Yavia. See this portion of the cladogram found in Guerrero & al. 2019. So yes, related, but still quite removed from each other.
Re: New Argentinian Pyrrhocactus?
Very interesting, thanks for the cladogram as well!
Also very intriguing to see Neowerdermannia and Yavia in the same clade.
