Re: Help my pelecephoria
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...

Re: 3 Eriosyce
Agreed the first two. Plants like E. villosa are variable as are many other Eriosyce.

Re: Could the maximum image size be raised?
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...

Re: Question on nomenclature
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...

Re: bifurcate areole
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...

Re: Turbinicarpus talk.
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.

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

Re: bifurcate areole
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...

Re: are all? cactus fruit edible
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...

I had just posted above and got around to my emails to find one of my branch members had sent me this translation of an excellent article originally in German of Acharagma. https://cdn.fbsbx.com/v/t59.2708-21/441428165_395777396775627_1449805364199008593_n.pdf/Escobaria_2023_EN.pdf?_nc_cat=107&c...

Re: Turbinicarpus talk.
No I think these talks are usually live and only a few recorded or if so the recording is only available for a few days afterwards. Some of the lecturers want to use those talks again to give to other societies or branches and if permanently available on the Web few would want to hear them at a club...

Re: Notocactus
Yes anttisep I I believe Wigginsia is the valid name over Malacocarpus but can't find the article by Porter explaining why, but they are both names for the same genus. Malacocarpus/Wigginsia's are close to Notocactus with similar flowers but usually have more pronounced ribs. As is usual sometimes w...

Re: Notocactus
Sort of a midway species between Notocactus and Malacocarpus. But placed in Notocactus rather than Malacocarpus. However if you are a "Lumper" both genera are now in Parodia.

BCSS Zoom talk on Rebutia/Aylostera
BCSS Zoom talk tonight 9th April. Talk is live not recorded so you need to Google for a time converter fto your local time. Not sure the time quoted is correct as Britain is now on British Summer Time = BST, one hour earlier than Greenwich Mean Time = GMT? https://mailchi.mp/95a610799f6c/bcss-zoom-t...
