unequal, ciliate or minutely bearded. Capsule flattened ; 

 seeds with a loose coat, pointed at one end. 



1. A. filifolia (Nutt.). Stems erect, branched, 3-6 dm. high; 

 leaves all filiform, 3-parted to near the base; herbage pubescent 

 with short reflexed hairs intermingled with scattered spreading 

 hispid hairs; heads several-flowered, terminating the branches; 

 bracts 3-lobed to near the base, the entire portion about 1 mm. 

 broad, strongly 3-nerved ; the lobes all filiform and usually nearly 

 equal, the outer surface very hispid with stout spreading hairs 

 rising from postulate bases, the inner surface concave, pubescent, 

 slightly elongated at the apex and tipped with a blackish, more 

 or less retuse gland; corolla purplish, 12-15 mm. long. (Cordy-
