Linaria - Linaria creticola - Taxonomy

Linaria creticola Kuprian., Acta Inst. Bot. Acad. Sci. URSS ser. 1 9: 63, tab. 2(5) (1950).

Glabrous, very glaucous perennial; fertile stems 1-5,10-15 (-20) cm, procumbent to ascending, slender, much-branched; sterile stems apparently absent. Leaves 3-10 x 1-4 mm, the length (2-) 2.5-6 x breadth, linear-lanceolate to lanceolate-ovate, acute, flat, attenuate or cuneate, thick-textured, opposite or 3-verticillate below, alternate above. Inflorescence with 1-10 (-15) flowers, lax in flower and fruit. Bracts 1-2 mm, linear, acuminate. Pedicels 1-5 mm in flower and fruit, erect. Calyx-lobes 1.4-2 x 0.4-0.6 mm, linear, acute. Corolla 8-13 mm, yellow; tube 1.5-2 mm broad; adaxial lip sinus 0.6-1.2 mm; abaxial lip sinus 0.7-1.8 mm; spur 3-5 mm, 0.5-1 mm broad at base, more or less straight, shorter than rest of corolla. Capsule 2-3 x 2-3 mm, globose, glabrous. Seeds 0.9-1.1 mm, crescenti-trigonous, somewhat compressed, black; longitudinal marginal ridges (2-) 3, 0.05-0.1 mm high, the intervening faces densely tuberculate or with sinuate, anastomosed, obtuse ridges; periclinal wall of testa cells, tabular, rugulate, not papillate. Modified from Sutton (1988).

L. creticola was described from chalky soils in the valleys of the upper Don and Donetz in European Russia. The taxon closely resembles L. cretacea from further east and the two species were treated as conspecific by Chater, Valdés and Webb (1972), though L. creticola is generally less robust with more branched stems, narrower leaves and smaller calyces. Kotov (1955) has recognized the taxon as a variety of L. cretacea and may be more appropriate to maintain L. creticola at some infraspecific rank.
