59. ANTENNARIA, Gaertii., II. Br. (Bristles of male pappus likened 

 to the anieniia of certain insects.) — rercnnial, mostly low, canescently and 

 often floccosely woolly herbs (occasionally glabrate), of north temperate and 

 arctic zones, with whitish or purplish flowers ; the bracts of the involucre pearly 

 white or rose-color, or brownish, never yellow. — Gicrtn. Fruct. ii. 410, t. 167

§ 1. Bristles of the male pappus hardly at all thickened but minutely barbellu- 

 late near the apex : akenes (in the first species) oblong-linear, obscurely 2-3- 

 nerved, puberulent ; the short hairs with 2-lobed and at length biuncinate tip, 

 after the manner of Townsendia: bracts of the campanulate or somewhat turbi- 

 nate involucre brownish, not radiant. 



' A. dimorpha, Toue. & Gray. I)r| nested, cespitose from a stout multicipital caudex, bear-
