i. Linaria Linaria (L.) Karst. 



Linaria pensylvanica Scheele in Flora 26: 586. 1843. "Aus 

 Pensylvanien." Described as differing from L. vulgaris 

 ( = L. Linaria) by having the raceme axis and pedicels

 varies freely between these two states. 

 Loam or sandy soil, fields and waste ground, common above the 



Fall-line, less common through the Coastal Plain. Naturalized 



from Eurasia.
