Gentiana puberula Michx 



sweet gum, beech, and red maple, and in the northwestern part of the state 

 it is found in moist black sand in interdunal flats about Lake Michigan, in 

 sandy flats in black and white oak woods, and in moist prairie habitats. 

 Infrequent, but where found several specimens may be found here and 

 there, growing singly.

6. Gentiana puberula Michx. {Dasystephana puberula (Michx.) 

 Small.) Downy Gentian. Map 1627. This is supposed to be a prairie 

 plant. Infrequent to very rare in moist, black, sandy soil in the open, 

 usually along roadsides and railroads and in fallow fields, low open woods, 

 and marshes. In two different years I made a collection of this species on 

 an open, rocky, black and post oak slope of the high hill at Stewart's 

 Landing about 3 miles east of Elizabeth in Harrison County. This seems 

 to be an unusual habitat but it was associated with other prairie plants 

 such as Liatris, Viola pedata, and Andropogon furcatus. Very rare here.

7. Gentiana flavida Gray. (Dasy Stephana flavida (Gray) Britt.) Yel- 

 lowish Gentian. Map 1628. This species has been reported from Cass, 

 Lake, Marshall, Monroe, Noble, Porter, St. Joseph, Steuben, Tippecanoe, 

 and Vigo Counties. I have it from the border of a very sandy black and 

 white oak woods in Lagrange County, from the roadside of a little used 

 road along a woods on a ridge in Perry County, and from moist soil near 

 Mineral Springs in Porter County.

8. Gentiana villosa L. (Dasystephana villosa (L.) Small.) Map 1629. 

 I have two collections of this species from Harrison County. It was first 

 discovered by Mrs. Chas. C. Deam. Both collections were made in the 

 southeastern part of the county in black and white oak woods. Only a few 

 specimens were found.
