Note that botanists differenciates what are called "thorns", "spines", "prickles" and "spinose teeth". They are all hard structures with sharp, or at least pointed, ends, all of them with the same function of mechanically deterring herbivory. In common language the terms are used more or less interchangeably, but in botanical terms, thorns are derived from shoots (so they can be branched or not), spines are derived from leaves (the entire leaf or some part of the leaf that leaves vascular bundles inside, like the petiole or a stipule), and prickles are derived from the epidermis and don't have vascular bundles inside. Leaf margins also may have teeth and if those teeth are sharp and pointed they are called spinose teeth.
