Well, that's not a cactus. Its a euphorbia... Euphorbia obesa, specifically.

Since this species is native to Africa, and since the only place you'd find it outside of Africa is in someone's ornamental plant collection... I'm assuming you probably dug this up from someone's yard or a botanical garden. Why not be nice and go put it back wherever you stole it from? It'd be good for your karma.

Where did you find that specimen?

It's very interesting..

My guess is that it belongs to the Genus: Astrophyton

anything more, no clue.

i actually live in colorado and found it growing wild about 50 miles south of denver. it was around alot of other cactus called prickly pear i think. this one just stuck out like a sore thumb so i took it home to nurture. anyways there is not a home for like 5 miles in any direwction so i dont think it could be from someones personal garden. well here is a pic of the other cacti it was growing around.

thanx for the input.

You found a E. obesa growing wild in Colorado?!?! Thats kinda fucked up. How is an African desert plant growing wild near Denver? Strange. Must've escaped from cultivation somewhere. I'm very surprised since Colorado is probably way too cold for this species, and that's a pretty big plant.

What do you think it is? Looks very typical of an E. obesa to me.

When you said E. Obesa i immediately thought to myself "duh" what was i thinking, definitely Euphorbia, but i wasn't completely sure about Obesa, just doesn't look exactly like an Obesa to me, and i'm skeptical as to how it got out there into colorado.

Obesa to me looks darker in the green heading to blue-ish with darker strips that there, plus the cactus growth areas, see in the light green (forms the star like shape) in this picture seem to be sunken into the cactus but has rounded old grown surrounding it.

Classic Obesa to me is more pointed in those spots than rounded, and the pseudo-spine stomates that stick out are more protruded than in the pic.

I'll have to search through a book or two here in my house see if i can come up with an exact species for that.

There are two forms of E. obesa, male and female. Its not a hermaphroditic plant. The two sexes do have some differences in appearance. Perhaps that's what's confusing you.

hmm, you might be right... but i'm also thinking maybe not, the differences are so stark. I'm gonna try and find some specimens around here.

Let me know... because that really looks like a typical E. obesa to me. I can't think of any other euphorbias that have that shape, but I'm not really an expert on euphorbias. All the pictures of E. obesa that I can find online look pretty similar too:

Definately a neat looking plant.

I had this feeling that there was another Species in the Euphorbia genus that was also rounded.. I don't know why, but so far i've found no other domed Euphorbias.. Most likely it is just a sex difference like you said. I'll keep tracking around though.

Hmm, neat. From what I'm reading, the difference between the obesa and symmetrica is that the symmetrica produces multiple buds per node, while obesa just has one. Apparantly there is some debate over whether these are two species or one ("Euphorbia obesa, E. symmetrica, two species or two names only?" by J. Ř?ha and R. ?ub?k, 1985).

Personally, I'm a cactus man, and don't know all that much about euphorbias. I have an E. obesa and an E. lactea, and occasionally grow poinsettas, but I've never really been fascinated by them like I am by cacti.

The genus really needs to be broken up thoug... I mean seriously, how can these little round obesa be in the same species as a leafy poinsetta or a columnar lactea? It's ridiculous!

you could cut it in halfe, the button that is, horizontally or Cut the button clean off leaving just a little of the button left at the base to callous over and regrow new parts.

Back away from the plant a little bit and take another picture. It's not in focus because your standing a little too close. Thanks!

I'll second that, Murple. Euphorbia sap is nasty. There's a weed here in England that is a Euphorbia of some sort, when I was a kid I got some sap in my eye. It didn't actually hurt at the time, but I had an allergic reaction and the next morning I couldn't open my eye because it was all gunged up with nasty horrible stuff. It was a week or so before the gunge was no longer created. Icky.

E. Obesa, also called "baseball cactus" it's sap is a white milkisch venom that will "bleed" out if cut or damaged.
