 Description

Plant at fl. c. 1–2–(2.5) cm. tall. Stem erect, mostly within lf-mould. Green lf 1–2 cm. long, sessile, orbicular-cordate. Floral bract much < ovary. Fl. standing directly over lf, the ovary erect. Per. barely 1 cm. tall. Dorsal sepal galeate, arching completely over labellum, acute; lateral sepals subulate, minute, seen only in front view between spurs. Petals smaller than sepals, sts barely discernible. Labellum forming a curved tube, its anterior margin abruptly deflexed under the tip of the galea in a semicircular papillose lobe that hides a median pouch; at the base on either side a narrow conical spur projects downwards between petal and sepal.
