The Small-strip ( Malaxis monophyllos ) is a plant from the genus Malaxis within the family of orchid (Orchidaceae). The range includes the temperate areas of the northern hemisphere from North America and Eurasia to the Philippines.
Surname
Other German names are strip (in this case a likelihood of confusion), single-sheet soft Wurz or Einblattorchis , which as well as the kind of epithet monophyllos refer to the characteristic single leaf of the plant. Heinrich Marzell regards all German names of the inconspicuous orchid as book names . The generic name Malaxis 'softening' comes from the Greek with a not exactly explained naming motivation; presumably the name initially referred to Hammarbya paludosa , which has only weakly developed roots (Exactly).
description
Vegetative characteristics
The small-flowered single leaf is an inconspicuous perennial herbaceous plant that reaches heights of 10 to 35 centimeters. The tuber ( pseudobulb ) is flat and greenish. Characteristic is a single, sometimes two basal leaves surrounding the stem . The simple, parallel-veined leaf blade is egg-shaped with a length of 4 to 9 centimeters and a width of 2 to 5 centimeters.
Generative characteristics
The flowering period extends from June to July. The relatively long, spiked inflorescence contains many loosely arranged flowers. The relatively small, greenish flowers are zygomorphic and threefold.
The number of chromosomes is 2n = approx. 30.
ecology
The small-leaved single-leaf is a fragile-looking plant that is dependent on high humidity and shade all year round. It therefore grows preferentially in moss cushions from Hylocomium splendens or in fern rhizomes from Asplenium viride , which have a high water storage capacity .
The pollination of Malaxis monophyllos done by fungus gnats . The pollinia are leaf-like; there are two pollinia superimposed in the anther. They are connected with a drop of adhesive fluid and are attached to the pollinator under the chin.
Occurrence
The distribution area of Malaxis monophyllos includes the temperate areas of the northern hemisphere of North America and Eurasia to the Philippines. It is the only European species in the genus Malaxis .
The Small-strip usually thrives in damp locations such as wet deciduous forests , wet meadows , fens and lime flat moors . It thrives in quelligen, shady, mossy slopes on sickerfeuchten, nutrient-rich and base-rich, mild to moderate acidic, humus-rich, loose, rocky or gravelly loam soils . It often occurs on rocks covered in moss or in humus gravel floodplains and grows in plant communities of the Alno-Ulmion association. In the Allgäu Alps in Bavaria, it rises to an altitude of up to 2000 meters on the Schrecksee . According to Baumann and Künkele , the species has the following altitude limits in the Alpine countries: Germany 40–1800 meters, France 1–1600 meters, Switzerland 700–1610 meters, Liechtenstein 1020–1570 meters, Austria 500–1800 meters, Italy 740–1900 meters, Slovenia 250–1600 meters. In Europe the species rises up to 1900 meters, in the Himalayas up to 3060 meters above sea level.
Systematics
Malaxis is a genus of orchids that is cosmopolitan. About 165 species belong to it. A list of the recognized species can be found in R. Govaerts.
The first publication of the Kleinblütigen Einblatts took place in 1753 under the name ( Basionym ) Ophrys monophyllos by Carl von Linné in Species Plantarum , p. 947. The new combination to Malaxis monophyllos (L.) Sw. was published by Olof Peter Swartz . Other synonyms for Malaxis monophyllos (L.) Sw. are: Epipactis monophylla (L.) FWSchmidt , Microstylis monophyllos (L.) Lindl. , Achroanthes monophyllos (L.) Greene .
There are three varieties:
- Malaxis monophyllos var. Brachypoda (A.Gray) P.Morris & Eames : It is distributed in North America from Alaska to other states of the United States.
- Malaxis monophyllos (L.) Sw. var. monophyllos : It is widespread from the temperate areas of Eurasia to the Philippines and occurs in the Aleutian Islands , Haida Gwaii and the Queen Charlotte Islands .
- Malaxis monophyllos var. Obtusa Tsukaya & H.Okada : It occurs only in Nepal .
