Traun Steiner orchid ( Dactylorhiza traunsteineri ) is occurring in Central Europe orchid. It is named after the Tyrolean pharmacist Joseph Traunstein ( 1798-1850 ). The style is very diverse, and can often be difficult to distinguish from Dactylorhiza majalis and particularly Dactylorhiza lapponica.

Features

Traun Steiner orchid is a perennial plant. It forms as a wintering organs two deeply divided, finger-like tubers. The stem is 10 to 40 cm high, thin and usually pithy. The upper stem region is red-violet to purple crowded. From habit ago affects the way slimmer and more delicate than the other members of the genus.

The plants produce two to four, rarely five leaves that extend upward to an angle. Their shape is linear- lanceolate, they are slightly keeled to rinnig folded. They are 3 to 15 cm long and 0.5 to 1.5 cm rather narrow. The leaf blade is usually mottled brown - purple, rarely it is not spotted. The top sheet is normally not sufficient to inflorescence.

The inflorescence is cylindrical, loose and fitted with usually less than 15 flowers. The bracts are shorter to slightly longer than the flowers and brown - purple color. The flowers themselves are purple. The outer tepals are narrowly ovate with 8 to 11 mm in length and 2.5 to 4 mm in width. The lateral outer tepals are erected at an angle. The middle is slightly raised or bent over the inner tepals. The inner Tepals 6 to 8.5 mm long and is inclined through the column. The lip is three-lobed and has an early middle lobe. Is 6 to 10 mm long and 7-13 mm wide. The bright central part has a purple pattern of loops, lines or points. The side lobes are chess or strongly bent downward. The spur is tapered, 9-13 mm long and 2 to 3.5 mm thick. He stands from horizontal or slightly bent.

The species is tetraploid.

Dissemination and locations

Traun Steiner orchid arrives in Europe and western Siberia from the temperat - montane to the boreal zone Flore. My site covers the Ozeanitätsstufen 1 to 5 (of 10). It grows in wet bogs down and swelling as well as in Lagg of raised bogs. It rises to 1700 m and avoids limestone bedrock.

In the Alps there is scattered before. In the southern Black Forest and the High-Vosges it is rare. The German populations north of the Alps and the Black Forest may be bastards.
