Plants perennial; taproot stout; caudex much-branched, woody. Stems many, decumbent to erect, usually simple, 10-40 cm, woody, pilose and glandular (rarely eglandular proximally). Leaves in 5-8 pairs, sessile but proximal ones narrowed into pseudopetiole, largest in mid-stem region, reduced proximally, scalelike at base, blade narrowly lanceolate to oblanceolate-elliptic or obovate, 2-6 cm × 3-20 mm, apex acute and acuminate, usually thick, leathery, densely puberulent and viscid-glandular or eglandular. Inflorescences cymose, open or congested, 3-15(-30)-flowered, sometimes compound, leafy. Pedicels to 1(-1.5) cm, shortly pilose, viscid-glandular, flowers sometimes sessile. Flowers: calyx prominently 10-veined, tubular, clavate in fruit, constricted proximally around carpophore, (20-)25-30 × 4-7 mm, papery, densely glandular-puberulent, viscid, veins parallel, green, with pale commissures, lobes narrowly lanceolate, acuminate, 5-8 mm, herbaceous; corolla pale greenish yellow to white, clawed, claw equaling calyx, ligulate, as broad as limb, limb 7-8 mm, deeply laciniate into 6 or more linear lobes, appendages oblong, laciniate, 2 mm; stamens equaling calyx; styles 3, exserted. Capsules equaling calyx, opening by 6 ascending teeth; carpophore ca. 3 mm. Seeds brown, reniform, 1.5-2 mm, margins papillate; papillae large, inflated. 2n = 48.
