There cao. we think, be no doubt of the propriety of referring this to the same genus with C. pratense.
Less, and DC., so weii figured by Humboldt and Kunth under the name of Unccia pratensis (Nov. Gen.
Am. t. 401). In our plant, however, the central florets have the limb quadrifid, and they are abortive. The
curious broad iucurved wing of the marginal achenia is quite smooth, not tuberculated.

Leaves in the lower part of the plant 4-5 inches long, ,9 broad. Lower bracteas leaf-like, small ; upper
ones acuminate subspinnlose, and gradually passing into the spinescent scales of the involucre. Receptacle
