Linaria bipunctata (L.) Chaz., Suppl. Dict. Jard. 2: 39 (1790).
Somewhat glaucous annual or biennial, glandular-puberulent in inflorescence, glandularpuberulent to subglabrous below; fertile stems 5-20 (-40), 14-32 cm, more or less erect to ascending, slender, diffusely branched above; sterile stems 0-12. Leaves of fertile stems flat or somewhat revolute, in whorls of 4-5 below, alternate above; leaves of sterile stems similar to those of fertile stems, mostly in whorls of 3-4. Inflorescence with 3-8 flowers, somewhat dense in flower, very lax in fruit. Bracts 1-3 mm, linear, subobtuse. Pedicels erect. Calyx-lobes somewhat unequal, linear-lanceolate to oblong, subobtuse; adaxial lobe 1.8-3 x 0.3-0.4 mm in flower and fruit; abaxial lobes 0.8-2.5 x 0.4-0.7 mm in flower and fruit. Corolla (9-) 11-16 mm, yellow with deeper yellow palate; tube 1.5-2.5 mm broad; adaxial lip sinus 1-1.5 mm; abaxial lip sinus 0.7-1.4 mm; spur 4-6.5 mm, 0.6-1 mm broad, straight or somewhat curved, much shorter than rest of corolla, often reddish. Capsule 1.5-3 (-3.5) mm, oblong-ovoid, glandularpuberulent above. Seeds tuberculate and papillate; hilum narrow; periclinal wall of testa-cells tabular, convex or papillate, densely verrucate, the anticlinal wall of testa-cells angular with ridge over junction. Modified from Sutton (1988).

a. Linaria bipunctata subsp. bipunctata.
Fertile stems subglabrous or sparsely glandular-pubescent below, branches diverging at a narrow angle throughout the length of stems. Leaves of fertile stems 6-20 x 0.3-0.5 (-1) mm, linear or subulate, evenly spaced along stems. Pedicels 1-3 mm. Seeds (0.5-) 0.7-0.8 mm, reniform-orbicular or somewhat trigonous, usually compressed with an encircling marginal ridge, blackish-grey; marginal ridge up to 0.05 mm broad, somewhat thin, wing-like; tubercles discrete, the distance between tubercles 1-2 x width of tubercles.

Basionym: Linaria glutinosa Hoffmanns. & Link, Fl. Port. 1(8): 237, tab. 39 (1811), excl. omn. syn.
Fertile stems densely glandular-pubescent throughout, the lowermost 4-6 cm unbranched, divaricately and often diffusely branched above. Leaves of fertile stems 2-9 x 0.6-2.5 mm, linear-lanceolate, widely spaced above, very crowded and caducous below. Pedicels 0.5-1.2 (-1.6) mm, crowded below, widely spaced above. Seeds 0.4-0.6 mm, reniform to reniformtetrahedral, usually without marginal ridges, black, shiny; tubercles more or less contiguous, often in curved rows.
