A genuine and well marked species, hitherto confounded 

 with the preceding. I have long noticed the specific differ- 

 ence between these two plants, and once called the attention 

 of the late Dr. Muhlenberg to it. With his usual caution 

 however he said " he wished to see further." I have observ- 

 ed them both in several parts of the United States, and found 

 them always retaining the same character. No. 2. is very 

 abundant on the high and woody hills near what is called 

 Hand's pass, on the Lancaster road It is also very common 

 on the great hills between York and Baltimore, and there the 

 other species is more rare. Both species are common in the 

 vicinity of the city of Washington. In the neighbourhood of 

 this city No. 1 is more frequent than No. 2, which however 

 is far from being rare. In grassy woods, near and above the 

 falls of Schuylkill. In the copses of the Neck ,- and in the woods 

 back of the Blue-bell Inn, on the Darby road. Annual. July, 

 August.
