Young branches glabrous, green. Leaves (3-12 × 1.5-5 cm) oblong, acute, attenuated at the base into a short petiole, strongly undulate, with large acute lobes, dentate, glabrous, deep green on both sides, covered with small glands which cause a very strong, fetid odour. Inflorescence corymbiform, with few capitula; capitula sometimes solitary, terminal or lateral. Peduncles short, usually with leaves. Capitula very large (3-6 cm in diameter) with numerous imbricate bracts, broad, with ciliated margins, coriaceous, acute. Flowers yellow, all tubular, without ligules.

Habitat:

Forests, thickets and rocky outcrops, on limestone or siliceous soils, in areas of semiarid, arid and even Saharan bioclimate.

Distribution:

Endemic to the NW of Africa. Morocco and Algeria. High Atlas (southern watershed and western area up to near Essauira to the N), Anti-Atlas, Bani mountains, westernmost Saharan Atlas and in general almost all other pre-Saharan and Saharan mountain systems of the region between the High Atlas, the Saguia el Hamra and the Saharan Atlas.
