Crassocephalum is a genus the common names of whose members include ragleaf, thickhead, and bologi. Several species are raised as leaf vegetables and used for medicine, especially in West Africa. Similar to Senecio , but differing in never having ray florets. A calyculus of short bracts (c.1/4 to 1/5 of the length of the inner phyllaries) is present. The genus is typically thistle-like in appearance, but all parts are soft and not spiny. ^[2]
