Inflorescence erect, 2–16 cm. high; flowers 1–5(8), distant; scape filiform, smooth above, usually papillose at the base; scales few, similar to the bracts; bracts basifixed, ovate-lanceolate, acute, more or less 1 mm. long; bracteoles similar but narrower; pedicels 0.5–1 mm. long. Calyx lobes subequal, the upper slightly larger, broadly ovate, acute, lower ovate-oblong, rounded or truncate. Corolla white or lilac with a yellow spot on the palate, 3–7 mm. long; superior lip narrowly oblong, more or less 1.5 times as long as the upper calyx lobe, with apex rounded, truncate or emarginate; inferior lip circular; palate raised, double-crested, the crest smooth or transversely tuberculate; spur conical-subulate, more or less twice as long as the inferior lip. Filaments filiform; anther-thecae subdistinct. Ovary ovoid; style very short; inferior lip of stigma semi-circular, the superior deltoid, much smaller.
