This, again, appears a very Protean plant in the foliage, which is entire, sinuato-pinnatifid, or deeply pinnatifid with linear spreading segments. The plant varies from two to six inches long, and bears one or many scapes, all the parts being more or less clothed with a soft subtomentose pubescence ; it has also been found at Cape Fan-weather by Capt. King.

Folia exemplaribus Falklandicis uncialia, Patagonicis 3-4-pollicaria. Caidis 4-6 unc. longus. Involucrum unc. longum. I have described this species partly from my own specimens, which are very imperfect, and partly from others gathered in Patagonia (Cape Fairweather) by Capt. King, where a second species occurs of which a diagnosis is subjoined.
