889. Tall Cone-flower. Rudbeckia laciniata. A smooth, 

 coarse, much branched herb, 3-8 ft. high. Leaves much 

 divided, the segments both toothed and lobed, the upper 

 leaves less divided or even toothless. Flowers yellow, the 

 heads about 2 in. wide, the center of the head cone-shaped. 

 Flower heads in large open branched clusters. In moist 

 places, Quebec to Florida, and westward. Not common as a 

 wild plant, but its cultivated form, the Golden Glow, with 

 more numerous rays is a common garden plant and some- 

 times escapes. Fig. 889. 



890. Black-eyed Susan. Rudbeckia hirta. A mostly un- 

 branched, rough-hairy biennial or annual weed, 1-3 ft. high. 

 Leaves basal and alternate, slightly toothed, mostly blunt, 

 and with 3-5 prominent veins. Flowers yellow, the heads 

 few or solitary, with a conspicuously dark, cone-like center. 

 In fields, Quebec to Florida, and westward. Not native in 

 the east, but common as a weed. July. Fig. 890. 



891. Sneezeweed. Hclcnium autumnale. A stout, mostly 

 smooth perennial, 2-6 ft. high, conspicuous because its 

 branches are winged from prolongation of the leaf bases. 

 Flowers yellow, the heads very numerous, in branched clus- 

 ters, the center of the head cone-like. In wet places, Quebec 

 to Florida, and westward. Also often cultivated and some- 

 times escaping. August. Fig. 891.
