Chironia laxa Gilg

A diffuse, much branched, herbaceous plant becoming slightly woody at the base, from about 20-50 cm tall, with very slender wiry, subterete or quadrate stems and branches. Leaves lanceolate, linear-lanceolate to linear, 6-40 mm long and 1.5-6 mm broad, acute or occasionally subacute, often acuminate to a long very acute apex, slightly cuneate at the base, the blade spreading to reflexed often with the apical half ascending. Inflorescence terminal on the branchlets, simple or in 2-3-flowered monochasial cymes, pedicels slender 1-4.5 cm long. Calyx about 7 mm long, obviously shorter than the corolla-tube; tube 2 mm long; lobes about 5 mm long, lanceolate, long acuminate, acute, midrib prominent in the lower half. Corolla 2-3 cm long; tube cylindrical about 1.1 cm long, narrowed into a distinct neck and slightly widened at the mouth, the narrow neck obvious above the calyx lobes, few nerved; lobes elliptic-oblong, as long as or slightly longer than the tube, subacute to distinctly acute at the apex, slightly cuneate at the base. Stamens inserted about 2 cm below the rim of the tube; filaments about 3 mm long; anthers 5 mm long, straight or very slightly twisted. Ovary about 1 cm long narrowing into the 8.5 mm, 2-lobed style; lobes lanceolate to linear, about 1.5 cm long, cohering at the base.
