Abstract: In view of the different opinions on the origin of the spines of Berberis, we studied the morphology and occurrence of the spines of Berberis by means of entity anatomy and paraffin section. The spines of Berberis descended from leaves, origins from leaf primordial, are leaf spines, not stem spines. It was clear that the spines of Berberis belong to one of the leaf metamorphosis types.

Key words: Berberis thunbergii var. atropurpurea, spine, origin
