Hi everyone,
I found this plant while doing fieldwork for a wetland project. It appears to be a succulent but was found along the margins and slightly inside the wetland itself (which doesn't seem very succulent-like to me). It has a very interesting growth pattern and colouring. As you can see, the leaves are green but with a purple-ish margin (this purple colour runs along the top of the branch as well). Very thick and fleshy. The branches are opposite with each consecutive pairing at right angles to the previous ones. I'll try upload another photo now.
