This plant agrees, in many respects, niinutely with the description 

 of the P. tenelia, by Retz ; but the flowers are neither nodding, ob- 

 tuse, nor fringed along the margins. Whenever the plants can be 

 compared they will probably be found distinct. It agrees somewhat 

 with the P. pectinacea, of which I believe Dr. Muhlenberg considered 

 it a variety ; but it is smaller and more decumbent ; and the interior 

 talve of the corolla when persistent, is appressed to the rachis. 



Grows in cultivated grounds. Common.
