Another orchid species found in the Tyrolean Lech Nature Park is the large two-leaf(Listera ovata). It grows to a height of 20 - 50 cm. The orchid has two opposite, egg-shaped leaves at the lower end of the stem. The inconspicuous 20 - 40 flowers are grouped in a raceme. The lower flowers of the raceme bloom first and only gradually the flowers above them. Thus, the seeds in the lowest seed pods are already ripe when the uppermost flowers begin to bloom. Pollination is carried out mainly by wasps.
The large two-leaf orchid is mainly found in forests, on semi-arid grasslands, in wet meadows and in fens. This orchid is also one of the fully protected plant species according to the Tyrolean Nature Conservation Ordinance 2006.
