Rudbeckia Sullivantu Boynton & Beadle 



I have had all our species of Rudbeckia under cultivation for several 

 years and this autumnal form of this species baffles me. I hope to continue 

 and to increase my observation of it. 



N. E. to Man., southw. to Fla., Colo., and Tex. 



2. Rudbeckia subtomentosa Pursh. Sweet Coneflower. Map 2113. 

 Infrequent in rather wet prairie habitats in the northwestern part of the 

 state, mostly along roadsides ; and in the southwestern part of the state in 

 low, open woods, where it is usually associated with prairie plants. 



Ind., Wis. to Kans., southw. to La. and Tex. 



3. Rudbeckia laciniata L. Cutleaf Coneflower. Map 2114. Golden- 

 glow is a cultivated form of this species. In our area, this species varies in 

 the pubescence of the lower surface of the leaves from glabrous to densely 

 short-pubescent. The rays of our plants are spreading. Infrequent, but 

 usually in large colonies, on the moist, alluvial bottoms of streams in the 

 open or in woods, and rarer in low woodland and about lakes. 



W. Maine to Man. and Idaho, southw. to Fla., Colo., and Ariz. 



4. Rudbeckia triloba L. Brown-eyed Susan. Map 2115. Infrequent, 

 but usually in large colonies in the open or wooded, moist banks of streams 

 and in moist wooded ravines. Throughout the state although there are no 

 reports or specimens from the northern counties. 



N. J. to Minn., southw. to Ga., La., and Kans. 



5. Rudbeckia fulgida Ait. Orange Coneflower. Map 2116. This is a 

 rare species found in dry, open woodland. It is slender, usually 4-8 dm 

 high, and grows in colonies. 



N. Y., Pa. to Mo., southw. to Fla. and Tex. 



6. Rudbeckia umbrosa Boynton & Beadle. Map 2117. My specimens are 

 from the low, moist border of a small creek about a mile southeast of 

 Corydon Junction (New Salisbury) in Harrison County. This species, no 

 doubt, has a wider distribution in Indiana. 



W. Va. to Ky., southw. to N. C. and Tenn.
