Flowers suberect or half-spreading, salmon, cherry-or coral-red; pedicel with ovary straight, slender, ± 17–25 mm. long.. Dorsal sepal erect or bent slightly forwards, very convex and almost hooded, broadly elliptical, rounded at apex, spurred near the base, ± 9 mm. long, 7–8 mm. broad when spread out, the spur horizontal or curving slightly upwards, narrowly cylindrical, 2–2.5 cm. long; laterals spreading, obliquely oblong-elliptical, obtuse, ± 1 cm. long, 4.5–6 mm. broad.. Petals erect, ± inside the hood of the dorsal sepal, oblong or obcuneate, obtuse, ± 7 mm. long, 2.5–4 mm. broad above.. Lip projecting forwards, oblanceolate from a narrow base, rounded at apex, ± 1 cm. long and 4 mm. broad.. Anther horizontal on a short (±1.5 mm. long) erect stalk, 3 mm. long.. Stigma in front of anther, broadly elliptical or nearly orbicular, 2 mm. in diameter.
