Hello friends!

I would like to research this new arrival before I repot it, but I have no idea what it is or where to begin.

Some ID help would be much appreciated.

By the way, this is my first post in "Succulents"!

Thanks,

Kevin

Euphorbia? Are those flowers and or seed pods?

Ya, they look like Euphorbia flowers.

Very interesting plant.

Thanks for the help with the ID, panosstravos88. Did you know that searching this plant name on google has some of your fotki photos of this plant come up on the first page?

Also, on the very first google hit I found this quote: "With its square, jointed, succulent stems, this fascinating pelargonium could easily mislead the casual observer into mistaking it for a member of the Euphorbia family". So, CC's and Tony's ID were not that far off.

Thanks, again.

There is a euphorbia that looks just like it, Euphorbia pteroneura. It should be easy to distinguish, does it have white sap?

Hello again. I repotted today, and yes, it has white sap. That said, and a little more research, it looks like I have a Euphorbia pteroneura.

It looks much like this plant: http://www.euphorbia.de/e_pteroneura.htm

Thanks, everyone.

I don't think it's E. pteroneura, but I have no better suggestions

No doubt euphorbia though. The flowers are dead give aways.

I think Karla's ID was correct. It turns out this is a variable species (yours looks nothing like mine!), and has often been confused with E. sipolisii....Legolas, if you collected it locally in Mexico, E. pteroneura is almost certainly the correct ID.

Thanks, lancer99. I had arrived at the same conclusion, that it was more likely an Euphorbia pteroneura, which is native to Mexico. The other potential was native to S. Africa. BTW, I did not collect the plant, I purchased it at a reliable nursury. Thanks, again!
