Type.

Without locality (lectotype P [Herb. Lam.], designated by Sa’ad 1967: 118).

Description.

Woody based perennial, branched at base with erect stems to 40 cm; vegetative parts appressed pilose to villous with spreading hairs. Basal leaves 1.5-6 × 1-4 cm. oblanceolate with a long attenuate base; stem leaves sessile, 2.5-5 × 0.1-0.3 cm. linear or oblong, acute or obtuse, entire, somewhat narrowed at the base. Flowers in many-flowered terminal heads; bracts 7-22 × 2-6 mm, oblong-elliptic or ovate, acute; bracteoles 7-8 × 0.5 mm, linear; sepals 8-9 × 2.5-3 mm, narrowly ovate and abruptly narrowed into a long fine point, margin somewhat scarious; corolla 1.5-2. 8 cm long, white or pink with darker midpetaline bands, weakly lobed with broadly triangular lobes; midpetaline bands dark, pilose; ovary glabrous; style glabrous, divided c. 4 mm above base; stigmas c. 4 mm. Capsule glabrous, seeds smooth, pubescent. [ Sa’ad 1967: 117; Silvestre 2012: 267; Polunin and Smythies 1973 (plate 38)]

Distribution.

France (Billot 3157, Roux 1877); Spain ( Jerónimo 4946, Miles at al. 311, 506, Bourgeau 332, 1297); Morocco (?).

Notes.

A somewhat variable plant, the type adpressed pubescent, but villous plants with spreading indumentum, e.g. Font-Quer & Rothmaler 12/1935 and Simpson 51450 are frequent. Some specimens are much reduced and cushion-like, mostly from mountains in Spain (Bourgeau 334, Lofthouse s.n. [21/6/1926]).
