Glaucous perennial, glabrous or rarely glandular-pubescent in inflorescence; fertile stems numerous, 5-26 cm, prostrate to ascending or sometimes pendent, simple or branched; sterile stems usually absent. Leaves 4-22 x 1.5-9.5 mm, obovate to broadly elliptic, subacute to obtuse, apiculate, flat, attenuate to petiolate, rnostly 3-verticillate, alternate above. Inflorescence few to many-flowered, leafy, more or less dense in flower, becoming lax in fruit. Bracts 8-20 rnm, oblanceolate to broadly elliptic, obtuse, leaf-like. Pedicels accrescent, (4-) 6-24 mm in flower, erect to erecto-patent, up to 25 (-42) mm in fruit, becoming strongly recurved on ascending sterns, straight on pendent stems. Calyx-lobes more or less equal, scarcely accrescent, (2.5-) 4-5 x (0.6-) 1.2-1.5 mm, linear-lanceolate, acute. Corolla 16-17 mm, white with blue or violet veins and yellow or orange palate; tube 2.5-3 rnrn broad at rnouth; adaxial lip sinus 2.5-3 mm; abaxial lip sinus 1.5-2 mm; spur 5-7.5 mm, 1.2-1.8 mm broad at base, straight, much shorter than rest of corolla. Capsule 3-4 x 3.7-4.5 mm, globose, glabrous. Seeds 1-1.5 mm, ovoid, oblong-reniforrn or reniforrn-trigonous, somewhat laterally compressed, the margin usually with encircling, somewhat inflated, occasionally interrupted, wing-like ridge, the intervening faces densely tuberculate with rounded tubercles, blackish-brown; hilum subbasal, narrow; periclinal wall of testa-cells tabular or tabular-convex, that of cells from interstices or base of tubercles usually papillate.
