Stems simple or branched, 20–40(–50) cm; branches ascending, quadrangular-ridged, scabridulous on faces and angles. Leaves spreading-ascending; blade linear, widened distally, 10–15(–20) x 0.4–1.5 mm, not fleshy, margins entire, midvein sometimes abaxially scabrous, adaxial surface scabrous; axillary fascicles shorter than or equal to subtending leaves. Inflorescences racemes, elongate, flowers 1 or 2 per node; bracts longer than pedicels. Pedicels ascending, 0.5–3.4 mm, glabrous. Flowers: calyx hemispheric, tube 2.5–3 mm, sometimes scabrous proximally, lobes triangular, 1–1.4 mm; corolla pale pink, without 2 yellow lines and red spots, 12–14 mm, throat pilose externally and villous within across bases and sinus of adaxial lobes, lobes: abaxial spreading, adaxial reflexed-spreading, 3–5 mm, abaxial pilose externally, adaxial glabrous externally; proximal anthers parallel to filaments, distal perpendicular to filaments, pollen sacs 1.2–1.7 mm; style included or slightly exserted, 4–7.7 mm. Capsules globular, 3.5–5 mm. Seeds dark brown, 0.4–0.6 mm.

Although Agalinis georgiana is listed as a synonym of A. fasciculata in some databases and floras, differences in anatomy and characters used in the key suggest that A. georgiana is distinct.
Agalinis georgiana is rare and known from southeastern Alabama, the northwestern panhandle of Florida, and south-central Georgia.
