features
This perennial herbaceous plant has an egg-shaped tuber as a persistence organ, which is replaced by a new one every year and survives the summer dormant. There are three to five leaves at the base of the stem and one or two sheathed leaves further up. The sepals are green and slightly curved forward. The lateral petals are wavy and yellow-green, often brown, at the edge. The blunt, three-lobed, dark brown, furry hairy lip becomes up to 25 mm long. It is curved downwards and has a brown mark, often with a bluish touch, which is bordered by a whitish to bluish, omega-like line.
