Plant to c. 20 cm tall. Stem slender, smooth, often reddish, internodes usually rather shorter than leaves. Petiolate leaves commonly but not invariably absent from flowering stem, forming separate rosettes; lamina c. 5-12 × 5-12 mm, ovate-orbicular, surface not strongly marked by veins; petiole well defined, sometimes longer than lamina. Cauline leaves several, for the most part sessile, the lowest one or two occasionally more or less like the rosette leaves; lamina c. 1.5-4 cm × 2-7 mm, linear-lanceolate to narrow-elliptic, the uppermost usually overtopping the ovary but rarely reaching the height of the galea. Flower usually solitary, erect. Dorsal sepal c. 1.5—2—(3) cm tall, the tip acuminate and usually more or less down-curved; lateral sepals diverging at a wide angle forming an open U or broad W shape from front view, this region abruptly prominent in side view, tips longcaudate- filiform and much overtopping galea. Petals almost as long as dorsal sepal, a broad, more or less horizontal marginal strip exposed making the width of the whole galea at the top 7-10 mm. Labellum narrow-triangular, arcuate, apex subacute. Column shorter than labellum; stigma elliptic, slightly prominent.

Caulis gracilis laevis saepe rubellus. Folia rosulata longe petiolata late ovatocordata. Folia caulina plerumque lineari-elliptica sessilia, inferiora interdum rosulatis similia plus minusve petiolata, supremum ovarium superans. Flos solitarius. Perianthium basi erectum dein plus minusve horizontale, galeae altitudino interdum 2 cm excedens. Sepala lateralia apice longe filiformia connata in labium inferius erectum late emarginatum abrupte prominens. Petala sepalum dorsale plus minusve aequantes apicem versus late explanata. Labellum lineari-triangulatum subacutum, columnam excedens. Stigma ellipticum prominulum.

Plant to c. 20 cm. tall, often less. Stem slender, smooth, often reddish, internodes us. rather < lvs. Petiolate lvs. in separate rosettes or at base of fl.-stem; lamina c. 5–12 × 5–12 mm., ovate-orbicular, surface not rugose; petiole well defined, sts > lamina. Cauline lvs several, mostly sessile, the lowest 1–2 sts ± like rosette lvs; lamina c. 1.5–4 cm. × 2–7 mm., linear-lanceolate to narrow-elliptic, uppermost us. overtopping ovary but rarely reaching height of galea. Fl. us. solitary, erect. Dorsal sepal c. 1.5–2–(3) cm. tall, tip acuminate, us. ± down-curved; lateral sepals diverging at wide angle forming U or wide W from front view, this region abruptly prominent in side view, tips long-caudate and much overtopping galea. Petals almost as long as dorsal sepal, a broad, ± horizontal marginal strip exposed. Labellum narrow-triangular, arched and protruding, apex subacute. Column shorter than labellum; stigma elliptic, slightly prominent.
