Characterized by a compact, more or less globose, head of flowers, held in the vertical plane with the lowest flowers opening first, and with most flowers held erect. Leaves oblong, oblanceolate or obovate-spathulate, attenuate into a winged petiole, often red at the base, erose-denticulate margin, rounded apex, often white farinose underneath when young. Scapes 10-30cm, often with farina near the apex supporting a head of lilac purple flowers, often with a darker colored ring around the eye. Bracts numerous, lanceolate and clustered below the head. Distinguished from P. capitata by having the flowers of the capitulum more or less erect (in P. capitata they are pendent). See also P. denticulata. Seems to take an intermediate position between section Denticulata and section Capitatae. Synonym P. crispa should not be confused with P. crispata.
