Delosperma Echinatum

Delosperma echinatum, also known as Pickle plant, is a succulent with strange-looking leaves, which have bristly hairs on small thin stems.
The leaves themselves are also prickly (but do not sting).
The most notable features are the water vesicles that cover the leaves. See our comparison of the size of pots we usually use and tips for caring for succulents and cacti here !
