stems short, tufted, simple, sparsely leafy, prolonged into naked peduncles; all parts glandularly-scaberulous; radical leaves spathulato-lanceolate, much attenuate at base, entire or repand, callous pointed, cauline linear-lanceolate, sessile, thickish, midribbed; inv. scales about 12, lanceolate, pubescent; achenes of ray oblong, bluntly trigonous, in the upper part minutely echinato-puberulent, below quite smooth, glossy, not wrinkled; disc-fl. with glabrous, acuminate teeth. Stems (including the peduncle) 12–15 inches high, leafy for about 2/3 their length. Radical leaves several, 2–4 inches long, cauline about 2 inches, all varying from 2 to 4–5 lines broad, the radical broader. Heads erect, on peduncles 3–5 inches long. Rays white above, purple beneath, with glandularly scabrous tubes. Allied to D. Ecklonis in foliage; differing in habit and in the achenes. Dr. Sutherland's specimens, so far as they go, agree with those of E. & Z. on which the species is founded.
