Plants (5-)8-45 cm tall. Tubers oblong or globose, 10-20 × ca. 10 mm. Stem (2.5-)5-23 cm, with 1-3 tubular sheaths at base, (1 or)2-5-leaved. Leaves cauline, alternate, widely spaced, green, lacking purple spots, linear, oblong-lanceolate, or elliptic, 3-15 × 0.2-3 cm, becoming smaller and bractlike above, glabrous, apex acute or acuminate. Inflorescence erect or slightly curved, 2-20 cm, glabrous; rachis 1.5-9 cm, (1 or)2-20-flowered; floral bracts lanceolate to ovate-lanceolate, 7-22 mm, lower ones foliaceous and exceeding flower, apex acuminate. Flowers often secund, pink, purplish red, or purple, medium-sized; ovary fusiform, 7-15 mm including pedicel, glabrous. Dorsal sepal erect, oblong or ovate-oblong, concave, 5-7(-8) × 2.5-4(-5) mm, 3-veined, apex subobtuse or acute; lateral sepals reflexed, ovate-lanceolate, oblique, 6-8(-9) × 3-5 mm, 3-veined, apex subobtuse to acuminate. Petals erect, forming a hood with dorsal sepal, narrowly ovate, broadly ovate, or narrowly ovate-oblong, oblique, 5-6(-7) × 3-4 mm, glabrous, 3-veined, apex obtuse; lip broadly oblong to obovate, 7-12(-15) × 7-13(-17) mm, spurred, 3- or 4-lobed above middle, margin crenulate, disk tinged white at base, marked with deep purple blotches; lobes variable; lateral lobes broadly oblong to subtriangular, falcate, 2-3(-5) × 2.5-5(-7) mm, apex obtuse or acute; mid-lobe oblong, square, or ovate, 1.8-3.5(-5) × 2-3.5(-6) mm, usually longer than broad, apex truncate to obtuse-rounded, subentire to distinctly notched and forming 2 lobules, often apiculate between 2 lobules; spur slightly pendulous or horizontal, sometimes distinctly curved upward toward apex, cylindric to cylindric-conic, often slightly attenuate, 7-15(-19) mm, usually slightly longer than ovary. Fl. Jun-Aug..

Distribution:

Amur, Assam, China North-Central, China South-Central, Chita, East Himalaya, Inner Mongolia, Khabarovsk, Korea, Manchuria, Myanmar, Nepal, Primorye, Qinghai, Tibet, West Himalaya.

Ecological:

In forests, alpine grasslands, limestone outcrops and scree at elevations of 500 to 4700 m as a mini-miniature to medium sized, cool to cold growing terrestria.

Flowering times:

Blooms in the late spring and summer.

Flower size:

1.5 mm.

Cultivation:

Pots:

A small plastic or pots that are not easily dried are recommended. Recommended number of bulbs would be one to two for 6cm diameter pot, three to five for the 7.5cm diameter pot and ten to fifteen for 10cm diameter pot.

Soils:

Well-drained rice-to-bean-sized pumice stones, Akadama (granular clay like mineral that is used as soil) and bog moss.

Watering:

After the sprout to flowering, a constant watering is necessary when you see the surface of the soil dried. After flowering, a good watering is appreciated after the soil dries up. During the high temperature season, it is best to water during early evening or at night.

In October to December, the surface part will become yellow and die. From this period to around March, you don't need to water but place them in non-freezing place and spraying a mist of water once a month will be a good treatment.

Indoor, a cup and a spoon are useful to water them.

Fertilizing:

The ideal fertilizing is 2 to 4 times per month of thinned liquid fertilizer. During the high temperature season, above 30 degrees Celsius, fertilization is not necessary.

Disease and pest:

For gray mold incidence (botrytis rot) where the flower dies from the root: 2 to 3 times per month of fungicide treatment during May and June. Cutworm and caterpillars: find them and remove them
