Obs. Mr. Schweinitz pronounced this to be his V. eriocarpa, described in Silliman's Journal; and re- 

 Jnarked that he wished to abandon that name, and restore the one he first gave it; viz. V. scabriuscula. Mr. 

 Le Coiite, to whom I showed a specimen in 1817, called it V. non descripta. 



I have never been so fortunate as to meet with V. concoZor, iij this vicinity; though I have always sup- 

 posed it must occur along the Brandywine.
