Flowers 3–7, uniformly yellowish green or nearly so (labellum ornaments occasionally more or less orange; anther occasionally cream). Sepals obtuse to acute, glabrous; dorsal sepal lanceolate-ovate to elliptic, 6.6–8 by 3.6–4 mm; lateral sepals obliquely triangular, 6.7–7.7 by 5.5–5.7 mm. Petals somewhat spreading, narrowly elliptic, slightly oblique, rounded to acute, 5.5–6 by 2.5–3.3 mm.
