Abstract
The systematic position ofPachyphragma macrophyllum (Brassicaceae) is unsettled. This species was either treated as a monotypic section ofThlaspi s.l. or was treated as a distinct genus.Gagria lobata apparently closely related toPachyphragma, was also given generic rank. To unravel the phylogenetic relationships ofPachyphragma andGagria, ITS sequence studies were conducted using as a reference representatives of the main lineages ofThlaspi s.l. The molecular data indicate thatGagria lobata andPachyphragma macrophyllum are closely related to members ofThlaspi s.str., an assemblage of species well separated from the otherThlaspi s.l. lineages.
