 County.

la. Grindelia squarrosa var. serrulata (Rydb.) Steyermark. The 

 variety, like the species, is becoming established in fallow fields, alfalfa 

 fields, and waste places in northern Indiana. I have specimens from St. 

 Joseph, Steuben, and Wells Counties. 



My specimens were determined by J. A. Steyermark who studied 

 the genus. 



Both the species and variety are western plants that have been intro- 

 duced and have established themselves. 



8844. CHRYSOPSIS Nutt. 



1. Chrysopsis villosa (Pursh) Nutt. Hairy Golden-aster. Map 2001. 

 Locally common in very sandy soil along roadsides in the counties indi- 

 cated on the map. This species is easily cultivated and is worthy of 

 cultivation, but, no doubt, it would soon spread if a congenial habitat were 

 nearby unless the seed were collected before they became mature.
