This species is said to be found in dry woods and thick- 

 ets from Anticosti, Nova Scotia, New Brunswick to British 

 Columbia, south to North Carolina, Kentucky, Minnesota^ 

 Iowa, and Arkansas. Britton and Brown, however, do not 

 include Iowa and Arkansas in the range of the species. 

 This species has been confused with Melampynnn latlfoUum 

 Muhl.; a more southern species, thus causing the southern 

 limit of the range of our northern species to be uncertain. 

 The species blooms from May until August. 



We have seen no Iowa specimens of this species. Prof. 

 Arthur in his catalogue reports the species from Lee 

 county.
