Most important morphological characters:

Medium-sized (slim) or even robust plant with oblanceolate, subsessile or petiolate, irregularly toothed (3–8 long teeth) cauline leaves. Most developed basal cycle leaves medium-sized with angle 60–100° of leaf base, with 3-divided leaf blades with unlobed and non-overlapped lateral segments without leaves with whole leaf blade. Flowers with fully reduced petals.
