1100 Excluded Species 



650. Xanthium echinatum Murr. This species has been reported from 

 4 counties and is referred to one of our native species. 



651. Xanthium pungens Wallr. This species I refer to Xanthium penn- 

 sylvanicum Wallr. 



652. Xanthium strumarium L. This species has been reported from 15 

 counties and I refer it, also, to one of our native species. 



653. Heliopsis scabra Dunal. Reported from all parts of the state. I 

 believe these specimens have been so named on account of the roughness 

 of the leaves. This character alone, however, is not sufficient to separate 

 them from Heliopsis helianthoides to which I think all of our Indiana re- 

 ports should be referred. This species is western and our native species 

 insensibly grades into it. The range of Heliopsis scabra is given as follows. 



Maine, Man. to B. C, southw. to N. J., Tenn., and Ark. 



654. Rudbeckia speciosa Wenderoth. Showy Coneflower. This 

 species is interpreted differently by authors, and in consequence, the range 

 of the species differs. Boynton & Beadle (Small's "Flora of the South- 

 eastern States," 1903) give the range as "Pa. to Va. and N. C." In Gray's 

 Manual, ed. 7, it is given as "N. J. and Pa. to Ga. and Mo." In 

 Britton and Brown's Illus. Flora, ed. 2, it is given as "N. J. to Mich., south 

 to Ala. and Ark." All of the reports for this species, no doubt, should 

 be referred to some other species. 



655. Helianthus altissimus L. E. E. Watson so named specimens I 

 collected in Lagrange County which I am now referring to Helianthus gi- 

 ganteus L. 



656. Helianthus ambiguus (T. & G.) Britt. I reported this species upon 

 the basis of specimens so named for me by E. E. Watson. I now refer 

 three of them to Helianthus hirsutus Raf. and two of them to Helianthus 

 strumosus L. 



657. Helianthus ambulans Watson. I am referring my specimens so 

 named by Watson to Helianthus strumosus L. 



658. Helianthus arenicola Watson. Several of my specimens, so named 

 by Watson, I am now referring to other species. 



659. Helianthus atrorubens L. This species was reported from Lake 

 County by Peattie. Buhl writes that a confirming specimen is lacking. 

 Since the range of this species is far to the southeast of our area, I believe 

 this report can safely be ignored. 



660. Helianthus borealis Watson. I reported this species from La- 

 grange and Steuben Counties upon the authority of Watson. I now refer 

 these specimens to other species. 



661. Helianthus exasperatus Watson. I reported this species from 

 La Porte and Warren Counties. I now refer these specimens to other 

 species.
