*Antennaria corymbosa E. Nelson, Bot. Gaz. 27: 212. 



Resembles A. parvifolia somewhat in the form of the leaves^ 

 but they are still narrower and have an altogether different pubes- 

 cence, being finely silky. It differs also in the more slender stem, 

 the smaller heads, and the coloration of the bracts, which are very 

 tomentose at the base, dark brown in the middle, and the upper por- 

 tion papery white, in the staminate head broadly elliptic and obtuse, 

 in the pistillate oblong, obtuse or acutish. The pappus of the stam- 

 inate flowers is white, broadly club-shaped at the end, that of the 

 pistillate dirty white, filiform. The sterile plant was unknown to Mr. 

 Nelson when his description was drawn, but excellent material is 

 found in our collection. It may also be nearly related to A. fedicel- 

 Jata Greene, which I have not seen ; that species, however, is de- 

 scribed as having ample spreading stem-leaves, and no reference is 

 made to the coloration of the bracts, which in this species is very 

 striking. It grows in low rather wet meadows, in large patches 2 or 

 3 m. in diameter, at an altitude of about 2000 m.

 Rydberg & Bcsscy, 514-3. 



*Aiitennaria bracteosa. 



Freely surculose-proliferous ; leaves of the stolons broadly spat- 

 ulate, petioled, about 2 cm. long, acutish or mucronate, white- 

 tomentose on both sides, but especially on the lower; stem-leaves 

 larger, about 3 cm. long, oblong or narrowly oblong-oblanceolate, 

 with a broad base, mostly acute ; flowering stem 3-4 dm. high, strict ; 

 heads rather densely corymbose, 7-8 mm. long, and 5-6 mm. in 

 diameter ; involucre campanulate, its bracts greenish and tomentose 

 below, papery white above, in the fertile head oblong or lanceolate, 

 acute or in the inner even acuminate, considerably exceeding the 

 disk; sterile head unknown. 



Nearest related to A. foliacca, which it resembles in habit and 

 leaves, but differs in having a much denser inflorescence and very 

 long bracts. 



Montana: Jack Creek, July 15, 1897, Rydberg & Bessey, 5144. 

 * Antennaria foliacea Greene, Pittonia, 3 : 279 ; Antcnnaria fenicel- 



lata Rydb. Bull. Torr. Bot. Club, 24: 303 ; not Greene. 



Characterized by the ample cauline leaves, much larger than 

 those of the stolons ; head slender-pedicelled, its bracts in several
