Flowering.

(April) May to July.

Ecology.

Rocky places, pastures in protosols and stony places, on limestone and dolomite, less frequently on schist or gypsum; [phone] m a.s.l.

Distribution.

Iberian Peninsula and NW Africa. E half of Spain, rarer towards the W. Spa.: (A) (Ab) Al Bu Ca Cc Cs CR Cu Gr Gu J Le Lo M Ma Mu Na (Or) P S Sg Se So Te To V Z. For a representative list of studied materials, see Suppl. material 1.

Notes.

This species is unmistakable because of its large ligules, which are very exerted, decurrent on the leaf sheath-especially those of the base and shoots-and pearly white, which makes its white-green tufts very striking. Its presence is indicated for the first time in the region of Extremadura (Spain).
