Antennaria campestris n. sp. 



Stem low, about i dm. high ; basal leaves obovate-cuneate, 2-3 

 cm. long and about i cm. wide, without a distinct petiole, i-ribbed 

 or indistinctly 3-ribbed, the upper surface glabrate in age; stolons 

 very short ; pistillate heads about i cm. high, bracts lanceolate, 

 the lower portion greenish, the upper brownish and ending in a 

 scarious white acute or acuminate tip ; staminate heads somewhat 

 smaller ; the white scarious tips of the bracts elliptical and obtuse. 



It is nearest related to A. neglecta Greene, from which it dif- 

 fers mainly in the low habit, broader basal leaves, and short 

 stolons. It is confined to the prairies and plains west of the Mis- 

 sissippi.
