Small Opuntia ID’s please.

Post by Mark07 »

I’m wondering if anyone would kindly ID these small opuntia for me please? I picked them up from The Cactus Shop in Devon on my way back from Cornwall (great shop by the way!) but most didn’t have any labels.

First one I’m pretty sure is incorrectly labelled:

This one i’ve ID’d myself but just wanted to double check :)

And the remaining without labels:

Thanks :)

The first one is probably O. bergeriana, which is said to grow to 3.5m, so not small!
The second, yes, that's an OK name and it's what Royston originally treated it as. However, if you read Paul Hoxey's three-part review of C. sphaerica (available via this page you might decide that Cumulopuntia leucophaea is a more appropriate name.
Really not sure about the others - O. fragilis and O. debreczyi??

Did the second one come with the collection data if not it would be wrong to put it on the label (imo)

It didn’t but looking at the Cactus Shop website it’s the only one that looks like it. You’re right though, I’ll take the collection number off the label.

Hi Mark
No.1, Phil could be right with O. bergeriana but the spines are not golden, so I would go with Opuntia soederstramiana a very common species in Southern Spain after it was brought back from Ecuador to act as fencing and animal fodder in the hot summers ( your plant looks just like mine ) the name O. occidentalis is given to a species that lives in Southern California and on 1 or 2 islands off the coast but that species has yellow flowers, and is thought to be a form of O. engelmannii

No.2, I agree with Phil that is RKH 59, the beautiful deep cream/caramel wool on the areoles is the giveaway. the other forms of sphaerica / berteri have paler or white wool.

No.3, I agree a type of Tunilla / Airampoa and I would go with one of the forms of Airampoa corrugata. Tony Roberts will be able to tell you, he sold me a plant just like this two weeks ago at the TSG meeting.


No.4 I have this plant under the name Opuntia fragilis var. denudata
