ACCESSIONS TO ANTENNARIA. 147 



i 



the stems rather low, that of the fertile 7 or 8 inches, of the 

 sterile 3 to 5 inches, the inflorescences of both corymbose and 

 of only about 5 heads : leaves in age subcoriaceous, 3-nerved, 

 the indument almost wholly deciduous from the upper face, 

 the blade longer than the petiole, oval-elliptic, acute, 2 inches 

 long, l}i broad: involucres in the fertile campanulate rather 

 densely arachnoid at base, the white tips of the scales not at 

 all conspicuous, short and ovate in the outer series, narrow 

 and very acute in the others : pappus-bristles in male with 

 short broad and obtuse tips lightly crenate. 



On hill tops, forming small mats, at Mountain Glen in ex- 

 treme southern Illinois, collected by Professor Carl F. Baker, 

 21 April, 1900; distributed by him, if at all, under the name 

 of ^. occidentalis ; but even the female plant has not the invo- 

 lucre of that species, and male pappus is very characteristic. 



Antennaria bifrons. Mature leaves of firm texture, 

 1/^ to 2/^ inches long, obovate-cuneiform, therefore without 

 proper petiole, deep-green and glabrate or nearly so above, 

 beneath closely tomentose, but young foliage even when full 

 grown quite hoary above ; stolons very short, with few leaves : 

 stems of fertile plants slender, erect, 7 to 11 inches high, its 

 bracts oblong-linear, acute, about four only and remote : 

 heads large, short-pedicelled and subcorymbosely glomerate ; 

 involucres well imbricated, the scales at base very distinctly 

 arachnoid-hoary rather than woolly, the white tips of none 

 equal to the herbaceous part, all acute : male plant not 

 known. 



This is a very singular species, the type specimens of w^hich 

 were collected by myself in an old pasture in sandy soil, near 

 Port Huron, Michigan, 9 June, 1909. By the form of its 

 foliage it should be an ally of A. neghcia, yet by the size and 

 especially the width of the same leaves, and by the short 

 stolons and long stems it looks like the other group. 



Antennaria pinetorum. Of the large-leaved group, the 

 foliage rather copious but not large, apparently not well endur-
