My few new ones, plus a question

[Phil Hocking]

Somehow I managed to buy just cacti this time. Nothing against succulents but the ones I fancied were ones that I knew would quickly die on me. Anyway, I was rather taken with the Thelocactus bicolor v. texensis, which has superb long central spines, but apparently that is an 'invalid name'. However, the websites I looked at didn't say what the valid name is. Also Stenocactus anfractuosus is apparently another name for S. crispatus. That's OK because I don't already have that one. The others are Echinocereus breviseta (presumably aka brevispina), Echinocereus hancockii, Echinocereus palmeri, Stenocactus multicostatus and Ortegocactus macdougalli.

T. bicolor var texensis is a name for a form of T. bicolor ssp bicolor.

Here's a close-up of that Thelocactus. It's quite different from the Thelocactus bicolor v. tricolor that I have. For a start it has a bud whereas my fair sized clump has never flowered. Then there are those central spines, which are actually thin and flat, not cylindrical.

That Thelo's a little beauty Phil!
Nice selection!

Hi Phil - The E. breviseta looks an attractive plant. Is it particularly rare / difficult, such that it merits a grafting and a ?£4 tag?

I think that the Echinocereus breviseta is a form (cultivar perhaps) of E. davisii or E. viridiflorus ssp davisii. It seems to lack the longer spine sof the normal form, but the dark small body suggest that to me.

There is an article in the CSSA Journal Vol 2 on Page 91 about a form of davisii called brevispina. It may be that one, in which case it isn;t very common, so worth its price no doubt.

[Phil Hocking]

Yes, well worth 4 quid as it is quite rare. Even better at 2 quid though, because I dithered so long I got it when they announced that all their plants were half price! Ditto the Echinocereus hancockii, which looked like it might develop some nice spines.I'm not keen on grafted plants but I can always take a piece off and try to root it, leaving the scion to make some offsets. Incidentally I left out part of the name - it is E. davisii v. breviseta

Maria, I spotted that Thelo after wandering around half a dozen times making my mind up. I had already got to my self-imposed quota but that one seemed special so I exceeded the quota (as usual!). I didn't really leave myself enough time to have a good look at all the exhibits, hence not many photos.

Phil, I bought an Echinocereus davisii ssp. brevispina 8 years ago at the National, a grafted one, seems to be very slow growing (as is the type!) and this year succumbed to RSM, I sliced the top off and regrafted, hoping the remaining stump will offset. I also bought seed of it from Koehres, and have one seedling, only time will tell if the spination develops the same.

I also have a large Thelocactus bicolor var texensis that now has four good sized heads - a very handsome plant!

Is your "Echinocereus breviseta" this Phil?

http://www.cactus-art.biz/schede/ECHINO ... spinus.htm

Breviseta would mean short bristles and brevispina short spines. In any case the gender would be wrong seeing Echinocereus ends in "us" it would be brevispinus or brevisetus

[Phil Hocking]

E. davisii v. brevispinus is the correct name. I don't think brevisetus exists, and as you say it should end in 'us' because Echinocereus ends that way. I do hope the spines develop like those at Cactus-Art.
