Tephrocactus Help With ID Please
This cactus came with an identification label of Tephrocactus hickbergensis 2018 DianeD offsets. Hoping someone in the TSG can assist with identification or references as to whether this is a valid species, as I can't find any mention online, or perhaps someone knows DianeD, who I cannot find in our membership directory. I enclose a picture of my plant, hoping this helps.

Re: Tephrocactus Help With ID Please
The easy bit: that's not a valid species name. Nor is the plant a Tephrocactus in today's concept of the genus (as in last week's Zoom meeting). It looks like it's a Tunilla... however, I'm loathe to suggest a species identification in what is probably the most poorly understood cactus genus. Tunilla sp.

Re: Tephrocactus Help With ID Please
Thank you, Phil. I shall relabel this plant as Tunilla spp. I miswrote the name on the label appearing after the date of 2018. It should have read as Geraldine D. I think I picked this cactus up in an assorted cacti tray I purchased from Chris L.Phil_SK wrote: ↑Tue Sep 29, 2020 4:39 pm The easy bit: that's not a valid species name.

Re: Tephrocactus Help With ID Please
Tunilla /Airapoa sp it may be , but from that photo it could also be a Corynopuntia, just a thought ?

Re: Tephrocactus Help With ID Please
I think I may be on the right track in finding an identification for my mystery Opuntiad. After more sleuthing, I have found a reference to Maihueniopsis darwinii var hickenii MK584. There is a business in Bulgaria that has it available for sale. I may order one to make a comparison with mine.

Re: Tephrocactus Help With ID Please
Cretainly, not that.
I too Ray thought it had a passing resemblance to corynopuntia.
Easy to tell in the flesh, but photos can be deceptive.

Re: Tephrocactus Help With ID Please
Well to be totally honest before reading anything else I thought a undernourished bulbispina (didn't know how best to put it)

Re: Tephrocactus Help With ID Please
I don't know about undernourished Chris but certainly grown in poor light, I think Corynopuntia would be a good place to start and Corynopuntia bulbispina is a good call Chris.
Babytoes if you could post a better picture, we might be able to nail it for you.

Re: Tephrocactus Help With ID Please
I have continued my detective work on the cactus yet to be identified, and I may be closer to the holy grail. I humbly offer Pterocactus hickenii, named after Cristóbal María Hicken, an Argentian botanist who had experience with the grass plains of Argentina. I defer to the TSG, in advance.
