146 LEAFLETS. 



pyramidal (not flat-topped). The specimens are on sheet 

 358998, U. S. Herb. The sheet may or may not be the same 

 cited once by Mr. E. Nelson (Bot. Gaz. xxxiv. 124) under 

 the name of A. argentea, var. aberrans. That author, how- 

 ever, saw nothing but what he called a ' ' racemosely panicu- 

 late inflorescence ' ' to distinguish between what he had and 

 the typical A. argentea. Also he reports that the sheet he 

 saw had " only pistillate plants." The sheet from which I 

 describe A. pyramidata holds six specimens, of which two 

 are plainly staminate, their involucres and flowers differing 

 from those of the pistillate as I have indicated. 



Some new types of broad-leaved species of the Atlantic slope 

 of the Continent are next subjoined. 



Antennaria Arkansana. Broad-leaved and with the 

 herbage of A. fallax nearly, but the plant smaller: basal 

 leaves well enduring the winter, 3 inches long, including the 

 petiole, the blade oval-elliptic, mucronate, 1/^ inches wide, 

 3-veined, green and glabrous above, though when young very 

 thinly and inconspicuously silky-hairy: stems of fertile plant 

 6 to 10 inches high, ending in a rather close cluster of 4 to 7 

 heads ; involucres campanulate, scarcely woolly at base, the 

 scales in no part obscured, oblong-linear, numerous but only 

 slightly unequal, the scarious tips of the very outermost short 

 and acute or hardly obtuse, of all the others narrow and acute 

 or acuminate : stems of sterile plant low, heads few; bristles of 

 pappus in this narrowly linear, with few and scattered serrate 

 teeth. 



In woods near Fulton, in extreme southwestern Arkansas, 

 B. F. Bush, 4 and 5 April, 1900 ; the plant said to be a denizen 

 of woodlands ; distributed by Mr. Bush as ^. occidentalis. The 

 leaves are greener than in that species, which by both the 

 involucres of the fertile plant, and the pappus of the sterile, 

 this is very distinct from that. 



Antennaria elliptica. Plant of the large-leaved group,
