Common Name
Texas Toadflax
Linaria canadensis (L.) Chaz. var. texanus (Scheele) Pennell; Linaria texana Scheele
Flora of Virginia Name/Status
Linaria texana Scheele
This species may be more widespread in Virginia than current records indicate because of likely confusion with the very similar Nuttallanthus canadensis. With a primary range is in the Midwest and western U.S., its nativity in Virginia and other Mid-Atlantic states seems doubtful. It is considered an introduction in our area by Weakley (2020). It is also sometimes treated as a variety (Linaria canadensis (L.) Chaz. var. texanus (Scheele) Pennell), the combination not yet having been made in Nuttallanthus).
Virginia specimens of Nuttallanthus need critical evaluation due to the similarities between the two species.
First collected by Fernald and Long in 1939 from "sandy fields and clearings southwest of Petersburg, no. 10,023." More recently, it has been collected in three counties (Isle of Wight, Nottoway, Sussex) by Chris Ludwig and in James City County by Lynn Loetterle. Apparently infrequent or rare in the Coastal Plain and outer Piedmont of se. Virginia. However, its distribution and status are poorly known.
