The three subspecies of Crepis neglecta are so different that, in my opinion, they should actually be considered separate species:
- Crepis neglecta subsp. neglecta: delicate plants with a bare calyx.
- Crepis neglecta subsp. corymbosa: delicate plants with bristly hairy calyx.
- Crepis neglecta subsp. graeca: stronger plants with a hairy calyx.
On Crete there is a fourth species, which is listed as a subspecies of Crepis neglecta by many floristic works, it is most similar to Crepis neglecta subsp. neglecta. In all subspecies the flower heads are nodding in the early bud stage. The diameter of the flower heads is relative small, about 1.5 centimeter.
