 acal Flora. 



Stem glabrous, rather stout, 1—3 feet hi^h, strict or 

 with erect or ascending branches; leaves linear, scabrous, 

 acute, ascending, 1—2 inches long, 1 — 2 lines wide; pedi- 

 cels longer than the flowers, ascending; calyx campanu- 

 late; the calyx-teeth triangular-subulate, about one-third 

 the length of the calyx-tube; corolla purple, 5—6 lines 

 long; capsule globose, exceeding the calyx, 2—3 lines in 

 diameter. 



This species grows in dry soil on the rolling prairies of 

 Iowa, Nebraska, Colorado, south to Louisiana and Kansas. 

 Its eastward range is not definitely known. Western Iowa 

 was for a long time considered the eastern limit of the 

 range. We have a specimen collected by Agnes Chase 

 along the Desplaines river. Thatcher's Park, Illinois. This 

 species blooms from July until September. 



The State University herbarium has a specimen from 

 Fremont county. Professor Arthur reported the species 

 from Pottawattamie county.
