ANTENNARIA ROSULATA.
Antennaria dioica var. Gray, Syn. Fl. I: pt. 2, 233. At least in part. 1884. Not DC.
The two sheets of the American plant found in the Columbia University herbarium differ considerably from European specimens in the same herbarium. The European is evidently a depauperate form of A. dioica or at least nearly related to it. The American plant, besides having a more trailing habit, possesses an almost turbinate involucre, of which only the innermost row of bracts have a broadly oblong obtuse papery appendage ; the outer ones are even destitute of scarious margins. The whole involucre is
densely white tomentose. Specimens seen : E. A. Mearns, no. 40, 1887, from the Mogollon Mountains, Arizona ; E. Palmer, no. 109, 1869.
