What is this plant please
I'd like for someone to identify a plant from these pictures please. The leaf is 4cm long. The plant is a bush about 1.5m high. The leaves are rigid and have vicious spines at the ends. The leaf is attached to the stem by a plate which can be seen in the pic. It looks very much like the front part of a Spitfire. The bush is quite rigid and you wouldn't want to fall into it.
