Description: Plant erect, 14-34 cm tall. Stem green, in the upper part purple. Leaves 4-7, narrow lanceolate, grooved folded, slanting ascending, in the upper part recurved. Basal leaves
rosetted, in the lower part embracing the stem. First and second cauline leave often only 1 cm long. Third cauline leave until 13 cm long, 0.6-1 cm broad. Forth cauline leave 8-12 cm long,
0.6-1.4 cm broad. Fith cauline leave 7-12 cm long, 0.7-1.5 cm broad. Sixth caulin leave 6-9 cm long, 0.8-1.5 cm broad. The uppermost cauline leave 4-7 cm long, 1.2-1.8 cm broad, like a
floral leave, reddish purple, embracing the stem. Floral leaves 3-5 cm long, 1.5-2.2 cm broad, greyish purple with dark purple veins. Inflorescence loose or little assembled, with (1-) 3-6 (-7)
flowers. Sepals and petals 2-2.5 cm long, outside greyish purple with dark purple veins, at the base little greenish, inside purple, forming a hood. Sepals rounded at the base, to 1.1 cm
broad, becoming linear at the summit.Petals rounded at the base, 0.5-0.8 cm broad, becoming oblong to linear at the summit. Lip 3.3-4.7 cm longum, divided into a hypochil (rearpart of
the lip) and an epichil (frontpart of the lip), mostly hairy at the central part between hypochil and epichil with light purple or whitish hairs. Liphairs 2 mm long. Hypochil at the base with 2
callosities, 4 mm long, keels 15-20° diverging. Hypochil 1.9-2.1 cm broad, 1.1-1.4 cm long, in the central part whitish to light purple, the outer parts dark purple. Epichil 2.2-3.5 cm long,
1.0-1.4 cm broad dark red-brown to dark brown or dark purple with dark purple veins. Lateral lobes of the hypochil almost not or only 2-3 mm longer than the hood of the sepals. Hypochil
not overlapping the epichil or not more than 1 mm. Ovary 1-1.5 cm long, 3 mm in diameter. Gymnostem (ovary pillar) narrow, 15 mm long. Pollen-mass dark olive-green. Plant allogamous
(cross-pollination). Flowering from the middle of May to the middle of June.
