Nomenclatural Notes on Cirsium lappaceum (Asteraceae, Cardueae) from Iran

Cirsium rechingeri Negaresh nom. nov. replaces C. lappaceum (M. Bieb.) Fisch. (1812), which is an illegitimate name, being a younger homonym of C. lappaceum Lam. (1778). Two new combinations and five lectotypifications are proposed here. Images of type specimens of C. rechingeri var. rechingeri, C. rechingeri var. ferox and C. rechingeri var. tomentosum are provided.
