Carduus acanthoides, known as the spiny plumeless thistle, welted thistle, and plumeless thistle, is a biennial plantspecies of thistle in the Asteraceae-sunflower family. Carduus acanthoides may exceed 6.6 ft in height and can form weedy monotypic stands. The stem and foliage are spiny and sometimes woolly. The plant starts from a flat basal rosette and then bolts an erect stem with occasional toothed, wrinkled, spiny leaves.
At the top of each branch of the stem is an inflorescence of one to several flower heads, each rounded, covered in spiny phyllaries, and bearing many threadlike purple disc florets. The achenes are 2–3 mm long, with faint lengthwise stripes.
