Ohs. I have no doubt this is the A. plantago, of Muhlenberg, and Bigelow; and probebly of Michaus, and 

 the Flora Philadelphica: yet it is unquestionably, I think, the plant described in Pursh, and Elliott, under' 

 the name of A. parviflora. A few years ago, there was much idle gossiping, in the newspapers, about iis 

 virtues as a cure for hydrophobia; but it soou experienced the fate of all such pretended remedies.
