Re: Please help? Gymnocalycium?

Probably G. horstii if it has a white flower and ssp. bueneckerii if pink. The problem is since the subspecies or variety was sunk into synonymy with G. horstii type form, virtually every picture you see as G. horstii is the pink flowered G, bueneckeri form, since being more attractive it is more co...

Yes, it certainly looks like a Stenocactus in that picture now.

Re: No good Lophophora books?

Not sure if you have to be a member of Kaktusy to obtain it? I wanted a copy of theirs on Eriosyce so one of their members obtained it for me from somebody he knew who did not want it. Depends if you can find a Kaktusy member who can obtain it? Occasionally they do appear in booksellers second-hand ...

Re: Frailea root loss

Is it in the growing season where you are since cacti can lose their hair like feeding roots in dry periods and regenerate later, because it looks pretty healthy? I tend to loose them as I keep them too dry and hot in summer. A good article on growing Frailea's ex-situ by Angie Money was in the BCSS...

Re: Am I A Parodia Scopa?

A variable species with variable spine colours. Problem is not all illustrations are always correctly identified when you Google.

Re: Challenge for Tephrocactus / Opuntia enthusiasts

Agreed. Looks like what I obtained at the Tephrocactus Study Group last AGM in UK as rossianus.

Re: Am I A Parodia Scopa?

Yes one of the "scopa group", a white spined form of it often given a separate specific or varietal name.

Re: jp29 - James Pickering

I suspected the worst since we had not heard from him for a long time and he was not well. James started off as a British cactophile a little earlier than I did since I only joined the British Society in the 1960's. However we never met as I would only have been 8 when he moved to the USA. But we re...

Re: identification needed, Oregon pipe?

Trichocereus (now lumped into Echinopsis). Either of what George says or hybrid of some kind since it is very floriferous for that size.

Re: Submitting photos

Yes, the problem with many Forums is missing images because they were hosted elsewhere. I just upload straight from my computer, having resized the pictures in Photoshop Elements. As to pictures on hosting sites, will not this site automatically resize what you see on screen if in a post? A computer...

Re: decomposed granite as a top-dressing?

For all top dressings, if not already dust free, always remove the dust with a fine sieve. I sometimes use crushed granite in the UK sold by builders merchants as "quarter inch to dust". However as you found if you don't sieve the dust out it sets just like cement. The dust is not so bad u...

Re: Is this “corking?”

That around the base is normal corking, or producing in effect a bark as trees do as a branch ages. As with humans some of us age faster than others so some plants may cork earlier than others, even of the same species or batch originally grown from seed. Also some harsher conditions may promote it,...

Re: Weird Gymnocalycium variegation?

Looks like sunburn to me. Sunburn will not necessarily kill the plant, it can grow out if the growing point is not damaged. However it may take a few years until all the scar tissue finishes down the base of the plant.

Re: Mammalaria

This video has been put on in the past showing you can even graft tubercles on Opuntia pads. Note that as with grafting on round stock the tubercles must overlap the vascular bundles (or rings) and not just be put in the centre of the stock because with tubercles the vascular ring is small (necessit...
