If it has thorns I would say it is also cytrosperma Johnstonii or maybe lasia spinosa. Johnstonii has recently been Tissue cultured and is now much easier to find. Though it hates cold anything below 55f can be fatal. In most cases cold temps will cause the foliage to turn colors. Here are some pictures of it the stems are molted like a reptiles skin. I have many of them growing now but most have some discoloration due to lower night temps.
