(d) Subsp. alpina (L.) R. Fernandes , loc. cit. (1975)

( Santolina alpina L. ):

Like subsp. (a) but stems usually at least 20 cm, and generally more than five times as long as the non-flowering shoots; leaves densely greyish-tomentose; segments 2(-3) on each side, shorter, wider, less divided; capitula up to 17 mm in diameter, subglobose in fruit. Calcicole. • C. Appennini.

Considered by some authors as merely a variant of (a), but differing considerably in the constant characters given above, and in being calcicole. Subsp. (c) is somewhat intermediate between subsp. (a) and 11.

Some plants from Romania, referred by authors to A. eretica , with lax indumentum of very thin hairs, leaves with 1—2(—3) distant, patent, narrowly linear or linear-spathulate, usually entire segments up to 2-3 cm on each side, capitula 20-30 mm in diameter, involucral bracts with hyaline or narrowly scarious margin, and achenes 2-5-3 mm, belong perhaps to another subspecies of A. eretica or represent a distinct species ( A. kitaibelii Sprengel , Syst. Veg. 3: 592 (1826)).
