Herbs, perennial. Roots numerous, fibrous.

Spikes narrowly cylindric, 3-40 cm, loosely to densely flowered, sometimes interrupted basally; peduncle 5-30 cm, white pubescent; bracts narrowly ovate-triangular to triangular-lanceolate, 2-3 mm, glabrous or pubescent at apex, keel thick. Sepals 2-4 mm, keel extending or not extending to apex, apex obtuse, rounded, or acute; lower sepals elliptic, keel broad; upper sepals broadly obovate-elliptic to broadly obovate. Corolla white, glabrous; lobes narrowly triangular, (0.7-)1-1.5 mm, patent to reflexed, apex acuminate to acute. Stamens adnate only to near base of corolla tube, exserted; anthers white, ovoid-ellipsoid, 1-1.2 mm. Pyxis fusiform-ovoid, ovoid, conic-ovoid, or narrowly conic-ovoid, 3-6(-8) mm, circumscissile near base, with 5-15 seeds. Seeds blackish brown, ovoid-ellipsoid to ellipsoid, 1.2-2 mm, angled, ventral face prominent to slightly flat; cotyledons parallel to ventral side. Fl. Apr-Aug, fr. Jun-Sep.

Although Plantago asiatica and P. erosa (P. asiatica subsp. erosa) have sometimes been treated as synonyms of P. major (J. Parnell, Fl. Thailand 9(2): 153. 2008), molecular evidence does not support this (N. Rønsted et al., Bot. J. Linn. Soc. 139: 323-338. 2002; N. Ishikawa et al., Amer. J. Bot. 96: 1627-1635. 2009).
