Oas. Our plant appears to be the var. latifolium, Hart. Phil. $ Eaton,~or tl>r 

 M. lat\folium< Muhl. <$• Ntttt. The nan ow-leaved variety, (which I take to be Un- 

 original of the M linearey Lam) is abundant in the Pines of New Jersey ; but I 

 lave not found it here. One other species is said to have been found in the U. 

 States.
