Sepals spreading, lanceolate to oblong-lanceolate, 12-18 × 2-3 mm, apex obtuse or acute. Petals similar to sepals, spreading, often slightly wider than sepals, apex acute; lip cordate-ovate when flattened, concave, 6-10 × 6-12 mm, 3-lobed near base; lateral lobes erect, ovate-triangular, 3-3.5 × ca. 3 mm; mid-lobe reflexed, ovate-elliptic, concave, 8-10 × 6-7 mm, lateral mar-gins nearly slightly erose and involute, apex acute; disk with 4-6 longitudinal, purplish red, papillose ridges; spur large and thick, 5-8 × 4-5 mm, apex obtuse.
