Hi Nino, Phil_SK did a comprehensive explanation of David Hunt's Cactaceae Systematics Initiatives here:- https://www.forum.bcss.org.uk/viewtopic.php?t=166280 https://caryophyllales.org/cactaceae/cdm_dataportal/taxon/8c8dfb49-cae4-40e2-998b-5494c396fbc1 Ritter used to do the same by publishing the t...

Hi Nino, As Arjen says the name change to "famantinensis" was published in David Hunt's "Cactaceae Systematic Initiatives" by Schlumpberger. This was the publication Hunt was using to update his "New Cactus Lexicon", which now will never happen after his death, with DNA...

It was recently brought to my attention that David Hunt's correction of Ariocarpus scapharostrus to Ariocarpus scaphirostris was probably invalid. Therefore the correct version is seemingly somewhere between the two - Ariocarpus scaphirostrus? https://www.cactusnames.org/ariocarpus-scaphirostrus/ &q...

As Nachtkrabb says there are quite a few similar Trichocereus. In fact I believe Kurt Backeberg even introduced a virtually spineless one as a grafting stock that was easier to graft onto having no spines. Many of the Trichocereus contain alkaloids, therefore were cultivated and spread around in S. ...

Scents are a matter of personal opinion since some people are more sensitive to some than others. No plants I know naturally use humans as pollinators so don't produce scent to suit us! It has been found many plants release their scents only at certain times of the day or night when their pollinator...

Cactus Shows and judging differ around the world wherever you go. Local ones are often judged by a general gardener with some classes for cacti among the garden plants, but specialist cactus shows usually use more qualified judges. Some countries rate fancy expensive pots highly in judging, whereas ...

Hi nachtkrabb in the UK we tend to insulate our greenhouses with bubblewrap in winter to save heating costs, though I also do running a cold greenhouse too. The problem is if left up all year with standard bubblewrap it only lasts a season of so before it disintegrates due to Ultra Violet light (UV)...

Never did know my left from my right! Really a case I need new glasses. Thanks for correcting. Also shows offsetting can be variable. The front E. magnificus is offsetting around the base like mad, whereas not one offset yet on the slightly larger plant behind it. I have also seem many E. warasii's ...

These are my plants. All plants vary but my E. warasii and E. claviceps tend to produce offsets high up the stem, even near apical even though the growing point is still growing and not damaged. I have only noticed this high offset production in some of the Eriocactus? Also it is normal for E. waras...

Daiv says it should be OK now.

Hi Hanazono,

I tried and got it also so have referred the matter to Daiv.

E. magnificus must be much rarer in Finland then since Uebelmannia's are far less common in the UK and fetch far higher prices. E. magnificus when first imported to Britain, being propagated in sunnier countries, used to have a beautiful bluish waxy epidermis, but that does not develop much in our s...

As shown above it is usually grown as a pendant plant in a hanging basket, unlike the usual C. silvestrii that grows OK in a pot on the stageing. As to its discovery see the following link that will usually translate using Google Translator or similar. http://www.incact.cz/index.php/82-chamaecereus-...

Yes Tony Santore, well known on YouTube from his "colourful" language sprinkled with F-words, but he knows his botany.

I'd go for G.pflanzii too.
