Argentina lineata (Trevir.) Soják

Various names has been used for this species, including Potentilla fulgens, P. lineata, P. siemersiana, and P. splendens. The earliest legitimate name is P. lineata.

Potentilla festiva and P. lineata are similar in external appearance, and were treated as conspecific for a long time. The auricles of the stipules of the radical leaves of P. festiva are connate from the base to the middle, whereas those of P. lineata are free. Moreover, P. lineata has gland-tipped, multicellular hairs as well as unicellular ones on the pedicels and abaxially on the hypanthium, whereas P. festiva has only unicellular hairs.
