A few succulents

[rrozzi]

Hi there,

I was allowed to pluck a few shoots from a nice succulents greenhouse at my university, and have begun to propagate them, but unfortunately the old man who maintains it has no idea what most of them are haha.

Any help would be greatly appreciated, I haven't even been able to identify the proper genera for most of them! Thanks so much.

1 - Austrocylindropuntia subulata (monstrose or normal)
2 - yes, Euphorbia seems likely
3 - might be some Tehprocactus
4,5 - stapeliads

I agree with Teo, but wanted to confirm the second one is definitely a Euphorbia and I'm pretty certain the third one really is a Tephrocactus, probably T. articulatus. The last two are both Stapelia. I think they are probably two different species but you won't know for sure what one until it flowers but I wouldn't be surprised if the second one is S. gigantea.

Just to add, Tephrocactus articulatus v. inermis.

Yep.

I'd agree with Stapelia gigantea for the Stapeliads, but you really need flowers to be sure.

You might be able to find an ID for the euphorbia by googling "euphorbia candelabra." Many species of euphorbia with that ribbed, pillaring growth habit are commonly known by that name. You might get lucky and find a match.
