Mean length of middle stomata in upper cauline leaves 44–45 µm. Polyploid, fide J.Kirschner,
Pl. Syst. Evol. 200: 5 (1996).
Endemic to Spain. 12: SPA. Mountain grasslands and open woodlands. Map 88.

An imperfectly known taxon, presumed to be a polyploid derivative of subsp. campestris. In
addition to the holotype gathering, only a single additional specimen is known. However, its
location, rather far from Sierra Nevada and in a different ecological situation, raises some
doubts about its identity.
