Stem (l-)5- 15(—30) cm, erect or ascending, with 0-3 leaves. Basal leaves 1-2 mm wide, linear to lanceolate, rarely widened towards the apex ( var. platyphyllum R. Schulz , from the Pyrenees), usually entire, very rarely remotely and shallowly serrate; cauline leaves narrowly linear to linear-lanceolate. Inflorescence 1-2 cm in diameter, globose. Bracts ovate, acuminate, shorter than to somewhat longer than the inflorescence, entire, rarely more or less dentate at base, glabrous or ciliate. Corolla dark blue, curved in bud. Stigmas 3. 2л = 28. Stony mountain pastures and screes', calcifuge. • S. & S. C. Europe, eastwards to E. Austria. Au Ga Ge He Hs It.

Polymorphic. Plants from the Pyrenees with wide upper cau­ line leaves have been described as P. serratoides Chouard, Bull. Soc. Bot. Fr. 99: 28 (1952) and others with long stems and longer bracts as P. gaussenii Chouard , op. cit. 26 (1952). The taxonomic value of such variants requires further investigation.
