Characteristics

A terrestrial herb 0.7–3 dm. high, glabrous except for the roots.. Tubers globose to ellipsoid or conical-fusiform, 6–32 mm. long, 5–14 mm. in diameter, ± densely tomentose.. Roots slender, flexuous, pubescent.. Stem erect, sometimes flexuous, rather slender, leafy.. Leaves 4–6; 1 or 2 lowest reduced to sheaths, acute, 2–3 intermediate ± spreading or suberect, lanceolate or oblong-lanceolate to broadly elliptical or elliptical-ovate, acute, up to 2.5-4 cm. long and 1.3–3.2 cm. broad, upper 1 or 2 smaller, adpressed to the stem, lanceolate, acute, often resembling the lower bracts.. Inflorescence cylindrical, 2.5–13 cm. long, 2.5–3 cm. in diameter, rather loosely 3–25-flowered; bracts erect, lanceolate or ovate-lanceolate, acute, 6–20 mm. long, the lower ones sometimes longer than the flowers.. Flowers spreading or half-spreading, pale pink to lilac or pale mauve; pedicel with ovary curved, slender, 8–11 mm. long.. Sepals and petals spreading forwards or slightly decurved, united with one another and to the lip in their basal third or quarter.. Intermediate sepal oblong-oblanceolate, obtuse or rounded, 8–9.5 mm. long, nearly 2 mm. broad; laterals obliquely oblanceolate-elliptical, rounded at apex, slightly shorter than the intermediate, ± 3 mm. broad.. Petals obliquely subspathulate-oblong, truncate at apex, 7.5-9.5 mm. long, 1.5–2 mm. broad; all tepals 2–3-veined.. Lip very convex, hooded, ± 7 mm. long, 5–6 mm. broad when spread out.. Spurs basal, much curved, diverging from ovary at base but decurved towards apex, slender, 5–8 mm. long, 1–2 mm. in diameter at base.. Column erect, enclosed in lip, the stalk slender, longer than the fertile part, altogether 5 mm. long; anther-loculi dependent, ellipsoid; stigma erect, broadly semi-orbicular, 1 mm. high, 1.5 mm. broad, rostellum broad, equally 3-toothed, the middle tooth bifid.
