Coreopsis 



Leaves and involucres glabrous 4. C. tripteris. 



Leaves and involucres not glabrous. 



Lower surface of blades and involucres more or less pubescent 



4a. C. tripteris var. Deamii. 



Lower surface of blades pubescent and involucres glabrous 



4b. C. tripteris var. intercedens. 



1. Coreopsis lanceolate L. Lance Coreopsis. Map 2143. Infrequent in 

 very sandy, dry soil on open dunes and knolls in the northwestern counties. 

 The species and variety are sometimes closely associated. The species is 

 much cultivated in gardens and doubtless our Marion County report should 

 be considered a garden escape. It has been reported also from St. Joseph, 

 Steuben, and Vigo Counties, where no doubt, it is native. The Vigo County 

 specimen was collected by Blatchley at Five-mile Pond. I have, however, 

 very thoroughly botanized Steuben County without finding it ; it may be a 

 garden escape in this county. 



Mich, and Lake Superior, southw. to Fla., Ala., La., se. Tex., and n. 

 N. Mex. 



la. Coreopsis lanceolata var. villosa Michx. {Coreopsis crassifolia Ait.) 

 Map 2144. My specimens and our reports of this variety are all from the 

 few northwestern counties shown on the map. The habitat is the same as 

 that of the species, but the variety is less frequent. 



Va., S. C, 111., Mo., and w. Ark., southw. to Fla., Ala., and La. 



2. Coreopsis palmata Nutt. Finger Coreopsis. Map 2145. All of my 

 specimens and all of the reports are from the northwestern part of the 

 state. It is infrequent and is found in dry, sandy soil in open woodland 

 and in sandy, prairie habitats. 



Ind., Minn, to Man., southw. to Okla. 



3. Coreopsis grandiflora Hogg. Big Coreopsis. According to Nieuw- 

 land, this species is well established along the Lincoln Highway near South 

 Bend and in a few other places in St. Joseph County. Doubtless it has 

 been introduced from the west. The seed may have been scattered
