this species and the next was gathered by Mr. Baker in 1866 at North Middleton near Wooler, in a field where they grew intermixed. The stem was about three feet high, the leaves similar to those of C. nutans but the spines rather feebler, the heads three to five in a cluster, mostly on distinct stalks but casually two together, two-thirds the size of ordinary C. nutans, and the outer phyllaries not more than half as broad and hardly at all reflexed. This form is about midway between C. nutans and the Continental C. acanthoides, differing from the former about as much as the latter does from C. crispus.
