Leaves
Leaves in verticils of 3–4, but often opposite or spirally arranged below on the same stem; petiole 5–24 mm. long, slender, with several 0.5–2 mm. long fimbriae crowded towards the top; lamina elliptical to elliptic-oblanceolate or elliptic-oblong, 2.2–9.5 cm. long, 1.1–4.1 cm. broad, slightly attenuate into the petiole at the base, the apex acuminate, acute; lateral veins 3–7 pairs; margin shallowly crenate-serrate, often obscurely so.
Inflorescences
Inflorescence a 1–4-flowered axillary subumbellate raceme; flowers rose-pink with a whitish spur.
Peduncles
Peduncle 11–31 mm. long, slender, suberect.
Bracts
Bracts linear-subulate, 2–3 mm. long, always more than the number of flowers in the inflorescence, only the lowest subtending flowers.
Pedicel
Pedicels 16–25 mm. long, slender.
Calyx
Lateral sepals triangular-lanceolate, 3–6 mm. long, subacute, somewhat asymmetrical. Lower sepal deeply and obliquely navicular, 10–13 mm. long, 4–9 mm. deep, abruptly constricted into a 25–38 mm. long curved filiform spur, which tapers gradually towards the tip.
Corolla
Lateral united petals 13–17 mm. long, with petals subequal in size; upper petal obovate, 11–14 mm. long, 7–9 mm. broad, somewhat asymmetrical, apiculate; lower petal obliquely obovate or suborbicular, 10–13 mm. long, 8–10 mm. broad, with a slight emargination or apiculum towards the top. Dorsal petal 10–12 mm. long, 15–16 mm. broad (when flattened), subcucullate, dorsally with a shallow crest terminating in a short acute point.
