dens cernua L. 



here along the highway by some sentimental, trans-continental tourists 

 who acted upon the ill advice published in a magazine a few years ago. It 

 was recommended that tourists should scatter seeds of conspicuous flowers 

 along the roadsides from coast to coast and from the Gulf of Mexico north- 

 ward. This produced a storm of indignation from botanists who knew that 

 such a procedure would destroy the natural range of species. 



The species has also been found about 3 miles south of Fort Wayne in an 

 open woods which has been used for years as a dump.

4. Coreopsis tripteris L. Tall Coreopsis. Map 2146. Frequent in the 

 lake area, where it is usually found in very sandy soil in open woodland 

 and fallow fields, in prairie habitats, and along roadsides. It is rare to local 

 in the southern part of the state, where it is found in small prairie areas 

 or in open woodland in the knobstone area.

4a. Coreopsis tripteris var. Deamii Standi. (Rhodora 32: 33. 1930.) 

 Map 2147. This variety has nearly the same distribution as the species, 

 but it is much less frequent. I have had both it and the species under cul- 

 tivation for more than ten years. In addition to the characters given in the 

 key, the variety may be separated at a distance by its darker green color 

 and earlier flowering period.

4b. Coreopsis tripteris var. intercedens Standi. (Rhodora 32: 33. 

 1930.) This form has been reported from the dune area, and I have a speci- 

 men from Whitley County. Doubtless it is rare. I believe this is only a 

 glabrate form of the preceding variety.
