Excluded Species 1101 



662. Helianthus giganteus var. microcephalus Peattie. Peattie reported 

 this variety from Lake County. I have not seen his specimen but doubtless 

 it is only a depauperate specimen of this variable species. 



663. Helianthus glaucus Small. Watson referred all of my specimens 

 which I had named Helianthus microcephalus T. & G. to this species. He 

 writes that the small-flowered sunflower of the interior should be known 

 as Helianthus glaucus and that the Coastal Plain form is the real Helian- 

 thus microcephalus. I believe that until the genus is better understood it 

 is best not to recognize this species, at least as a species. 



664. Helianthus instabilis Watson. Watson named many of my speci- 

 mens this species. I now refer them all to Helianthus grosseserratus 

 Martens. 



665. Helianthus laetiflorus Pers. Watson referred several of my 

 specimens to this species. I am excluding the species from our flora and re- 

 ferring specimens so named to the yellow flowered form of Helianthus 

 rigidus (Cass.) Desf. 



666. Helianthus leptocaulis (Wats.) Blake. I reported this species 

 from two counties upon the authority of E. E. Watson. I now refer these 

 specimens to other species. 



667. Helianthus tomentosus Michx. This species has been reported 

 by five of our early authors. Its range as now understood is to the southeast 

 of Indiana. 



668. Helianthus tracheliifdlius Mill. This species has been reported by 

 six of our early authors. Since I have not been able to find a confirming 

 specimen, it is excluded. 



669. Helianthus virilis Watson. The specimens so named for me by 

 Watson I am now referring to Helianthus hirsutus Raf . 



670. Coreopsis auriculata L. This species has been reported from 

 Clark and Steuben Counties. The known distribution of this species is 

 south of Indiana, but it may be found in the southern part of the state. 

 Since there is no verifying specimen, it is excluded. 



Va., Ky. to 111., southw. to Fla. and La. 



671. Coreopsis major Walt. Reported from Lake County without any 

 data concerning its distribution. If the determination was correct, the 

 plants were doubtless migrants, since the range is south of our area. 



Va. to Ky., southw. to Fla. and Miss. 



672. Coreopsis tinctOria Nutt. Reported from St. Joseph County by 

 McDonald as an escape along roadsides. Since it is not stated that it has 

 become established, I believe it best to consider it as a temporary escape. 

 Nieuwland says that it probably will not maintain itself. There is a speci- 

 men in the herbarium of Purdue University collected by Dorner in 

 Tippecanoe County, which is labeled, "Escape." 



Minn, to Alberta, southw. to Nebr., Ariz., La., and Tex.
