7. Rudbeckia Sullivantii Boynton & Beadle. (Rudbeckia speciosa var. 

 Sidlivantii (Boynton & Beadle) Rob.) Sullivant Coneflower. Map 

 2118. Local in moist, wet, or springy places about lakes and marshes and 

 along streams and roadsides. 



Ohio to Mich., southw. to Ala. and Tenn. 



8. Rudbeckia palustris Eggert. Map 2119. Common in sandy soil in 

 the wet, sandy, sedge border of the southwest side of North Twin Lake 

 about 2 miles northwest of Howe, Lagrange County, and on the spill bank 

 of the inlet of this lake where it was a much smaller plant. 



Ind. to Tenn. and Mo. 



9. Rudbeckia Deamii Blake. (Rhodora 19: 113-115. 1917.) Deam 

 Coneflower. Map 2120. A single colony of this species was found in 

 1914 and in the same place in 1916 on the moist slopes of the north bank 

 of Wildcat Creek in section 1 in Carroll County, about 150 feet east of where 

 the creek is crossed by the Delphi and Frankfort pike, about 9 miles south- 

 east of Delphi. The type locality was visited in later years and the species 

 had disappeared. I have searched up and down the creek from this place 

 and I have never been able to find additional specimens. In September, 

 1932, I found a large colony of it in a roadside ditch about a mile and a 

 half southwest of Williamsport in Warren County.

9178A. BRAUNERIA Necker 



Leaves of an ovate type, the lower ovate, the upper ovate-lanceolate, abruptly nar- 

 rowed at the base, 5-nerved, the margins, at least some of them, more or less ser- 

 rate; stems in our specimens smooth or nearly so; awn of chaff about as long as its 



body 1. B. purpurea. 



Leaves of a lanceolate type, attenuate at the base, entire or somewhat denticulate; 

 stems scabrous or rough-pubescent; awn or chaff shorter than its body. 

 Rays drooping, mostly 3-6 cm long; tips of awns of chaff indurated and some of them 



more or less hooked IB. pallida. 



Rays spreading or slightly reflexed, mostly 1.5-4 cm long; tips of awns of chaff in- 

 durated, straight or nearly so 3. B. angustifolia. 



1. Brauneria purpurea (L.) Britt. (Echinacea purpurea (L.) Moench 

 of Britton and Brown, Illus. Flora, ed. 2.) Purple Coneflower. Map 

 2121. In prairie habitats and woodland. Very local. The prairie seems to 

 be its preferred habitat. The published records are from the area of Dela- 

 ware, Jay, Randolph, and Wayne Counties, the Lower Wabash Valley, the 

 "barrens" of Floyd and Harrison Counties, and from Carroll, Cass, 

 Franklin, Marshall, Tippecanoe, and Vigo Counties. In the woodland I have 

 seen only isolated specimens. 



Pa., Mich, to Iowa, southw. to Ga., Ala., and Ark. 



2. Brauneria pallida (Nutt.) Britt. (Echinacea pallida (Nutt.) Britt.) 

 Pale-purple Coneflower. Map 2122. All of our reports say that this 

 species was found along railroads, and it is probably a railroad migrant in 

 this state. I found it along the railroad east of Dune Park in Porter
