Obs. Mr. Nuttall once considered this plant as the L. 

 glaucifolius, though I suspect he has changed his opinion on 

 re-examining it. According to Jacquin, that species has blue 

 flowers ; and it also appears to differ in several respects. It 

 is not described by Kunth. Mr. Nuttall found it in the Ar- 

 kansa Territory.
