Endemic ? Ir.-Tur. element. T. cadmeum is smaller than either T. chiliophyllum or T. argyrophyllum, and in its stature and spreading habit is more similar to the more easterly T. densum. In size its leaves are similar to the last-named species, but the lobes do not remain contiguous in the adult condition, as they generally do in T. densum, and are clearly separated one from the other and linear in shape, The phyllaries are fairly densely tomentose and the ligules are only slightly longer than the involucre.
