) in the 26–35 mm long spur, that is often only slightly coiled, the entirely white flowers with yellow and very small spot-like purple marks on upper lateral petals, the leaves, stems and flowers almost glabrous, and the occurrence in mid-altitude forest at 1100 m.
Plants prostrate to ascending, stem 15– 30 cm long. Leaves, stems and flowers almost glabrous. Leaves shining vivid green on upper surface, lighter green on lower surface, petiole 11–20 mm long, with 2–3 pairs of extrafloral nectaries, lamina ovate, 45–66 × 27–39 mm, margin with 10–11 pairs of extrafloral nectaries. Inflorescence with 4–7 flowers, peduncle 2 mm long, pedicel 15–26 mm long. Flowers entirely white with yellow and very small spot-like purple marks on upper lateral petals. Lateral sepals 6–8 × 2– 3 mm. Lower sepal navicular, 10–12 mm long and 4–5 mm deep, abruptly constricted into a spiraled, usually filiform spur, spur 26–35 mm long, often only slightly coiled. Dorsal petal 10–13 × 12–15 mm. Lateral united petals up to 25 mm long, upper lateral petal 14–16 × 7–8 mm, base of upper lateral petal with dark pink or red and yellow maculae, lower lateral petal 19–21 × 8–10 mm. Ovary 4–6 mm long, glabrous. Fruit 14–15 × 5–6 mm, glabrous.
