that the species is mostl}^ near the coast. In Iowa the 

 species occurs in damp soil, blooming in August and Sep- 

 tember, and is infrequent. Type locality: "Babitat in 

 Virginia, Canada." 



On August ly, 1900, we found in Johnson coui>ty a consid- 

 erable colony of this species by the roadside associated with 

 Geranlia tenuifolla. The purple flowers were an inch 

 long, the leaves linear, and slightly scabrous. The forms 

 a^rea very well with specimens collected near Lake Mich- 

 igan, Indiana, by Agnes Chase. The vState University has 

 a specimen from Emmet county collected by Mr. Cratty. 

 Prof. Bessey reported the species from Story and Powe- 

 shiek counties; Prof. Fink from Fayette county; Prof. 

 Pamniel from Hamilton county; Messrs. Barnes, Reppert, 

 and Miller from Scott and Muscatine counties; and Mr. 

 Miller by note from Henry county.

Stem about 10 inches high, glabrous, paniculately 

 branched; leaves narrowly linear; pedicels exceeding the 

 vertically compressed corolla, often longer than the leaves,

This species is common in fields and thickets, usually 

 preferring low dry or rather moist soil, and blooming in 

 August and September. The species ranges from Ontario 

 and New England to Manitoba and Minnesota, south to 

 New Jersey, Florida, Alabama, Louisiana, and Arkansas.
