--><p><i>Berteroa</i> mutabilis (Ventenat) de Candolle, native to northeastern Italy, the Balkan Peninsula, and northern Turkey, is known in North America only from a handful of collections almost all made more than a century ago as garden escapes in Kansas and Massachusetts. Although it was included by R. C. Rollins (1993), who indicated that it had not been collected for 60 years, the species apparently did not become naturalized in North America and, therefore, is not included here. From <i>B. incana</i>, B. mutabilis is easily distinguished by having winged instead of margined seeds, and flat and glabrous versus inflated and pubescent fruits. As indicated by I. A. Al-Shehbaz (1987), the record of <i>B. obliqua</i> (Smith) de Candolle from the Catskill region, New York, was based on misidentified plants of <i>B. incana</i>.</p>
