1. LrnartraA 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
