Stems branched, 30–100 cm; branches ascending-spreading, subterete to obtusely angular, finely ridged, glabrous or sparsely scabridulous. Leaves spreading, proximal sometimes reflexed, distal appressed; blade linear, 8–35 x 0.5–2 mm, margins entire, siliceous, adaxial surface finely scabrous; axillary fascicles absent. Inflorescences racemes, flowers 1 or 2 per node; bracts shorter than pedicels. Pedicels spreading, often upcurved distally, (6–)10–30 mm, glabrous. Flowers: calyx turbinate-campanulate, tube 3–5.5 mm, glabrous, lobes triangular-lanceolate, 0.8–2.5 mm; corolla pink, with 2 yellow lines and red spots in abaxial throat, 15–35 mm, throat strongly upcurved, glabrous externally and within across bases and sinus of adaxial lobes, lobes: abaxial spreading, adaxial erect to spreading, 4.5–8(–10) mm, equal, glabrous externally; proximal anthers parallel to filaments, distal perpendicular to filaments, pollen sacs 3–4 mm; style exserted, 12–17 mm. Capsules globular-ovate to oblong, 5–8 mm. Seeds dark brown to black, 0.5–1 mm. 2n = 26.
Phenology: Flowering mid Jul–Oct.
Habitat: Grasslands, old fields, pastures, open mesquite plains, dunes along Gulf Coast.
Elevation: 0–200 m.
Discussion
Within the flora area, Agalinis strictifolia and A. edwardsiana are restricted to Texas. They are distinguished by characters given in the key and those mentioned in the discussion for 9. A. edwardsiana.
