Inflorescences 1-flowered, or 2 or 3 flowers fascicled in leaf axils, without peduncles. Pedicels 2-2.5 cm, densely pubescent, bracteate at base; bracts linear. Flowers white, pink, or purple, simple or double petalous. Lateral sepals 2, ovate or ovate-lanceolate, 2-3 mm. Lower sepal deeply navicular, 13-19 × 4-8 mm, pubescent, abruptly narrowed into an incurved spur; spur 1-2.5 cm, slender. Upper petal orbicular, apex retuse, mucronulate, abaxial midvein narrowly carinate; lateral united petals shortly clawed, 2.3-2.5 cm, 2-lobed; basal lobes obovate-oblong, small; distal lobes suborbicular, apically retuse; auricule narrow. Stamens 5; filaments linear; anthers ovoid, apex obtuse. Ovary fusiform, densely pubescent. Capsule broadly fusiform, 1-2 cm, densely tomentose, narrowed at both ends.
