Summary Pak, J.‐H. & Bremer, K.: Phylogeny and reclassification of the genus Lapsana (Asteraceae: Lactuceae). – Taxon 44: 13‐21. 1995. – ISSN 0040‐0262. A cladistic analysis of 40 morphological, fruit anatomical, and chromosomal characters in the five species of Lapsana and eleven other species of the Lactuceae (Crepidinae) shows that Lapsana is polyphyletic. The genus is redefined to include only the European to S. W. Asian Lapsana communis and its allied taxa usually treated as subspecies. The four E. Asian species formerly placed in Lapsana are transferred to a new genus, Lapsanastrum, and the new combinations L. apogonoides, L. humile, L. takasei, and L. uncinatum are made.
