Petiole to 20 mm long; blade ovate-elliptic to elliptic to obovate-elliptic, 1.5-8 x 0.8-3 cm, acute to obtuse at apex, acute to attenuate at base, both surfaces nearly glabrous with trichomes restricted to primary and secondary veins and margin. Inflorescence of terminal, sessile to pedunculate, cylindric, densely bracteate spikes of 2-8 cm long, 10-15 mm in diam. near mid spike; peduncle to 4 mm long; rachis not or hardly visible; cymes usually 3-flowered, sessile; bracts obovate, 5-8 x 1.5-3 mm, aristate at apex, prominently 3-veined, abaxial surface pubescent with flexuose to flexuose-antrorse eglandular and inconspicuous glandular trichomes; bracteoles lanceolate to narrowly elliptic to oblanceolate, 3-7 x 0.5-1.5 mm, aristate at apex, usually venose, abaxial surface pubescent like bracts, secondary bracteoles similar to bracteoles except somewhat smaller. Flowers subsessile; calyx 3.5-7 mm long, abaxially pubescent like bracts, posterior lobe obovate, 3-6.5 x 1-3 mm, aristate at apex, usually venose with 3 prominent longitudinal veins, lateral lobes lance-subulate, 2-3.5 x 0.3-0.6 mm, with 1 longitudinal vein, anterior lobes oblanceolate to narrowly elliptic, connate for a greater distance than other lobes, 2.5-5.5 x 0.5-1.3 mm, aristate at apex, each with 1 longitudinal vein, usually ± venose; corolla white with irregular pink markings on lower lip, 4.5-6 mm long, tube cylindric, 2.5-4 mm long, limb externally pubescent with eglandular trichomes, upper lip 1.5-2 mm long, 2-lobed, lobes rounded, 0.1-0.2 mm long, lower lip 1.8-2 mm long, lobes subcircular, 1.2-1.3 x 1-1.2 mm; stamens 4, longer pair 1.8 mm long, shorter pair 1.3 mm long, thecae 0.3-0.4 mm long, parallel, ± equally inserted on longer stamens, unequally inserted on shorter stamens, unappendaged at base; style 3-3.5 mm long, curved toward lower lip of corolla at apex, proximally pubescent with eglandular trichomes, stigma subcapitate, 0.2 mm long, lobes inconspicuous. Capsule 3.5-4.5 mm long, pubescent near apex with erect to flexuose, eglandular trichomes; seeds 4, 1-1.2 x 0.9-1 mm.
