Perennial herb to 3.5 m. tall, though generally 0.5–1.5 m.; stems erect becoming somewhat woody and leafless below, simple or moderately branched, finely pubescent, especially when young, or glabrous.. Leaves spirally arranged; petiole 0.5–5.2 cm. long, slender, glabrous or finely pubescent; lamina ovate to lanceolate, lanceolate-oblong or broadly elliptic, 3.5–20 cm. long, 2.2–8.5 cm. broad, the base subrounded to attenuate, the apex acute to acuminate, finely pubescent or glabrous above and beneath; lateral veins 5–11 pairs; margin crenate or rarely serrulate, with several ± 1–2 mm. long fimbriae towards the base of the lamina.. Flowers axillary, solitary or in fascicles of 2–3, epedunculate, mauve, pink or deep rose with a whitish spur.. Bracts linear-subulate, 2–4 mm. long, inconspicuous.. Pedicels 3.5–7.5 cm. long, slender, glabrous or sparsely pubescent.. Lateral sepals 2, lanceolate-oblong, 4–8 mm. long, 1–3.5 mm. broad, glabrous.. Lower sepal shallowly and rather obliquely navicular, 10–16 mm. long, abruptly constricted into a 30–48 mm. long, curved filiform spur, generally with a few scattered hairs.. Dorsal petal obovate or suborbicular, emarginate, 10–19 mm. long, 10–24 mm. broad, dorsally with a shallow crest terminating in a short acute point.. Lateral united petals 14–25 mm. long; upper petal of each pair elliptic-reniform to reniform-oblanceolate, 10–26 mm. long, 6–13 mm. broad, entire, often with a short apiculum at the end; lower petal transversely semi-elliptic or obovate, 11–21 mm. long, 5–16 mm. broad, entire and with a short apiculum near or at the end, or with a small emargination along the inner margin about three quarters the distance from the base of the petal..
