FLOWERING PLANTS AND FERNS OF INDIANA. 891 



Tippecanoe (Cunningham); Daviess (Clements); Jefferson 

 (Barnes); Monroe and Vigo (Blatchley); Putnam (MacDougal); 

 Noble (Van Gorder); Jay, Delaware, Randolph, and Wayne (Phin- 

 ney); Clark (Baird and Taylor); Franklin (Meyncke); Gibson and 

 Posey (Schneck); Vermillion (Wright); Knox (Spillman); De- 

 catur and Shelby (Ballard); Fayette and Cass (Hessler); Hamilton 

 and Marion (Wilson). 



P. bifida Beck. Cleft Phlox. 



On sandy hillsides and dry open woods in several counties. Or- 

 dinarily in considerable quantity in the stations where found. 

 Probably of general occurrence. 



Flowers in April and May, at times continuing through June 

 in the northern part of the State. 



Lake, Starke, Vigo, and Monroe (Blatchley); Tippecanoe 

 (Coulter). 



P. subulata L. Ground or Moss Pink. 



In extremely dry, sandy or rocky soils. Its low habit of growth 

 and botanically unpromising stations have doubtless prevented 

 more numerous reports of its occurrence. Probably found in 

 most of the northern counties. 



Flowers from April through June. 



Tippecanoe (Cunningham); Clark (Baird and Taylor); Kosci- 

 usko (Coulter); Jefferson and Montgomery. 



POLEMONIUM L. 



P. reptans L. Jacob's Ladder. Greek Valerian. Blue-bells. 



In shaded, rather damp places throughout the state. The In- 

 diana forms are of stronger stem habit, and the entire plant 

 more hairy than indicated by descriptions. The same is true of 

 Illinois forms examined. A comparison with eastern material 

 at the Gray herbarium shows that the western form is easily dis- 

 tinguished by the characters indicated. 



Flowers in April and May. 



Tippecanoe (Cunningham); Hamilton and Marion (Wilson); 

 Daviess (Clements); Jefferson (Barnes); Noble (Van Gorder); 

 Jay, Delaware, Bandolph and Wayne (Phinney); Dearborn (Col- 

 lins); Clark (Baird and Taylor); Franklin (Meyncke); Gibson and 

 Posey (Schneck); Monroe and Vigo (Blatchley); Putnam (Mac- 

 Dougal); Vermillion (Wright); St. Joseph (Kizer); Decatur 

 (Ballard); Fayette (Hessler); Knox (Spillman).
