Hypanthium campanulate, oblong, or obconic, scaberulose; calyx lobes linear or linear-triangular, 7-22 mm, with (1-)4-7 teeth on each side. Corolla bilabiate, purple, purple-red, rose-purple, or blue-purple, 20-31 mm, outside scaberulose below, inside villous; upper 2 lobes linear, slightly longer than lower 3. Filaments connate above base, filament tube glabrous or sparsely shortly pubescent; anther tube glabrous or white hirsute only at base; lower 2 anthers barbate at top. Capsule oblong or ellipsoid, 8-16 × 4-9 mm. Seeds ellipsoid, finely striate. Fl. and fr. Sep-Nov.
