Regarding names of hybrids and cultivars as I understand it. Strictly speaking the cultivar name usually only applies to the one selected plant and not all other seedlings from even the same fruit or batch. Probably a lot of the fancy names we see are "selling names" rather than registered...

Older cactus plants that have lost their roots can take up to a year before re-rooting, just standing there seemingly doing nothing. If you cut the original root back to clean green tissue then allowed it to callous over for about a week you can root it in a gritty mix as suggested. The problem with...

Agreed the first two. Plants like E. villosa are variable as are many other Eriosyce.

We are not alone as modern phones and cameras are now churning out ultra large files which the Web has not kept up with. The BCSS Forum has had similar problems:- https://www.forum.bcss.org.uk/viewtopic.php?t=175314 Basically as I understood it anything of greater resolution than most forum users co...

Basically you are back to the old "Lumper" or "Splitter" argument as to if you think they are different enough to warrant separate species? In theory you could have just one genus for the Cactaceae using the oldest generic name and having a single species if you lumped everything...

The basic difference is that in the past we had morphological classifications based on a plants either visible similarities or differences and now we have classifications based on DNA. OK when the DNA agrees with morphology, but raises questions when it does not. For instance even though lumped on v...

Sorry about that. Just checked with the original link I was given and that no longer works so must have expired shortly after I posted it.

Presumably the migration via the groove on the Coryphantha tubercle was an earlier stage in the areole separation leading to Mammillaria type?

In Coryphantha the two parts of the areole are joined by a groove along the top of the tubercle. https://www.cssgc.org/CactusID/CactusIDTalk-AreoleSheet.pdf "Of the 1438 species accepted in the most recent taxonomic synthesis of the Cactaceae family, ∼85 % have monomorphic areoles; trichomes, s...

To be honest I don't know, so have forwarded your question to Daiv.

I would not advise eating fruits from plants in your collection if you use systemic insecticides and also contact ones if they get sprayed on the fruits. The type of fruit tends to depend on how its seeds are spread. If through birds etc that eat them they tend to be fleshy, whereas if seed are spre...
