north of the Smoking River, in lat. 56°. North America. Mr. 

 Di'unimond. — The variety ji. is a remarkable one. The whole 

 plant is more compact, the leaves less dentato-ciliate, and less 

 closely imbricated : the spikes solitary in all the specimens, 

 and supported on a peduncle scarcely more than an inch in 

 length.

 cent. — This species, were it better known, would probably be 

 found not to be distinct from L. aristatum or L. divaricatum ; 

 but being without specimens, we are unable to decide the point 

 satisfactorily. As far as we can judge from the descriptions, 

 the synonyms we have brought together evidently refer to 

 the same plant.
