The margins have 3-5 convex teeth, although they can also rarely have straight edges. [2] The flowers are yellow with 10-40 florets that grow from a ringed base. The discoid flower heads are mostly borne in terminal corymbs with a ringed base of dense stalked glands. [2] They are present between October and January. [3]
