The general habit of this species, is much taller and 

 stricter than the former species. The flowers have a re- 

 markably deep blue or indigo color with scarcely a tint of 

 red ID them. It is almost exclusively found in swampy 

 meadows, or on the grassy margin of small branches. Not 

 rarely it flowers there indiscriminately with the former, al- 

 though it begins to appear rather later. The following con- 

 trast of the characteristics will serve to distinguish the two 

 species-

The Sororia of Pursch and Willdenow belongs decidedly 

 to the next, which I think specifically different-
