Type : No-horn
Scientific name
Orchis anthropophora
( L. ) All.

The orchis anthropophora ( Orchis anthropophora (L.) All. , Syn .: Aceras anthropophorum (L.) WTAiton ) is a type of the plant genus orchids ( Orchis ) within the family of orchids (Orchidaceae). The species was previously placed in the monotypical genus Aceras .

Surname

The botanical generic name is Orchis "testicles". The specific epithet anthropophora consists of the Greek words άνθρωπος anthropos “man, man” and φερείν pherein “to carry”.

The German name is Ohnhorn. Also very common is the name Ohnsporn , which refers to the missing spur. The names Hanging Man , Puppenorchis and Fratzenorchis allude to the "human-like" flower shape . In Italian usage, the plant has the beautiful name "Ballerina".

Habit and leaf

The Ohnhorn is a relatively delicate perennial herbaceous plant that reaches average heights of 20 to 40 centimeters. This geophyte forms relatively small, rounded, egg-shaped tubers as persistence organs. At the end of the flowering period, a new sprout forms from a daughter tuber, from which the leaves shoot in autumn. The plant survives the winter with green leaves; this feature indicates its Mediterranean origin (high winter precipitation in connection with little frost are favorable growth conditions for the plant).

The foliage leaves are approximated in rosettes in the lower part of the stem , while they surround the upper stem in a sheathed manner. The relatively many (about four to nine) shiny and vivid green leaves are elongated-lanceolate in shape.

Inflorescence and flower

The high, filigree inflorescence contains up to 100 flowers . The hermaphrodite flowers are zygomorphic and threefold. The flower size is 12 to 14 millimeters. The egg-shaped, red-edged sepals (sepals) and the slightly shorter lanceolate petals (petals) form a hemispherical helmet. The labellum (lip) is spurless, 12 to 15 millimeters long, drooping, greenish / ocher yellow to brownish / orange-red. The two tips of the middle lobe are a little longer than the side lobes. There are two typical calluses at the base of the lip . The adhesive discs of the pollinia are fused.

The flowering period of the Ohnhorn extends from the beginning of May to the end of June. After that, the plant, including the leaves, is quickly obsolete.

The number of chromosomes is 2n = 42.

ecology

The Ohnhorn is one of the few Central European orchids that are visited and pollinated by beetles and small click beetles. The spurless flower enables the beetles to access the nectar with their short mouthparts.

distribution

The Mediterranean, sub-Mediterranean, Atlantic area of distribution of the Ohnhorn extends from North Africa , Spain , the Balearic Islands over the entire Mediterranean area, including the islands to Lebanon . In Central Europe there are deposits in France to the south of England and the Alpine countries , but not in high mountain areas. According to Baumann and Künkele , the species occurs in the Alpine countries within the following altitude limits: Germany 80–2280 meters, France 1–2660 meters, Switzerland 260–2710 meters, Liechtenstein 470–2200 meters, Austria 350–2700 meters, Italy 80–2970 meters , Slovenia 90-2180 meters ahead. In Europe it rises to 2970 meters, in the Himalayas up to 3900 meters above sea level.

The Ohnhorn is a floral element of the Mediterranean, Central and West Sub-Mediterranean, South and Central Atlantic, South Sub-Atlantic Florence zones. It is one of the sub- Mediterranean representatives in the flora of Central Europe . It is one of the more inconspicuous native orchid species. In recent years a certain spread of this plant species has been observed in Central Europe.

In Germany there are scattered distribution areas in Baden-Württemberg (especially on the Upper Rhine ), Rhineland-Palatinate (especially on the Moselle and Eifel ), in Saarland and very rarely in North Rhine-Westphalia (extreme southwest), Hesse (northeast; Bergstrasse), South Lower Saxony , Bavaria ( Maintal region , Rhön ), isolated sites in Thuringia and Saxony-Anhalt .

In Austria the species is found in Lower Austria and Carinthia . In Switzerland , the ohnhorn occurs mainly in the cantons of the Swiss Jura and in the Rhone Valley.

Due to the mild winters of recent years, this species has been observed to spread to previously too cold areas.

Location

The Ohnhorn loves sunny hills, short- grass rough lawns and light bushes on dry to moderately fresh soils. This type of plant is limestone and extremely thermophilic by our standards . Therefore, the occurrence is limited to particularly warm places.

It is found in the plant communities, especially the Mesobrometum from the Mesobromion Association, but also occurs in the societies of the Geranion sanguinei association (for a breakdown see: Plant sociological units according to Oberdorfer ).

Conservation and endangerment

Like all orchid species found in Europe, the Ohnhorn is also subject to strict protection by European and national laws.

Not found in the other federal states or anointed (Lower Saxony).
  • Red List Switzerland: VU (Vulnerable)
  • Red list Austria: no information available.

The population development in Germany is increasing slightly. The losses due to site destruction are offset by some new discoveries.

Systematics

The botanically valid species name is Orchis anthropophora (L.) All. in Fl.Pedem. 2: 148, 1785.

In a 1997 revision of the orchid species by Bateman on the basis of genetic traits, the hornless horn was classified as Orchis anthropophora together with some other species in the genus Orchis ( Orchis ) . This name is sometimes already used as a valid new name (Kew-Garden), but has not yet been fully established and is not entirely undisputed even among experts (see notes in Orchis ustulata ).

In addition to the Basionym Aceras anthropophorum W.T. Aiton 1814, there are other synonyms based on the same type :

  • Orchis anthropophora (L.) All. 1785
  • Arachnites anthropophora (L.) FWSchmidt 1793
  • Satyrium anthropophorum (L.) Pers. 1807
  • Loroglossum anthropophorum (L.) Rich. 1817
  • Himantoglossum anthropophorum (L.) Spreng. 1826
  • Serapias anthropophora (L.) Jundz. 1830

Subspecies, varieties, hybrids

× Orchiaceras bivonae
× Orchiaceras bivonae
× Orchiaceras spurium
× Orchiaceras spurium

Neither subspecies nor varieties of the Ohnhorn are known, if the names of nomenclaturally irrelevant flower colors are dispensed with.

Aceras anthropophorum is very closely related to the Orchis militaris circle of shapes and hybridizes with its species: orchid orchid ( Orchis militaris ), Italian orchid ( Orchis italica ), purple orchid ( Orchis purpurea ) and monkey orchid ( Orchis simia ).

For example:

  • × Orchiaceras bergonii (Nanteuil) EGCamus (Syn .: Orchis × bergonii Nanteuil ) = Orchis anthropophora × Orchis simia
  • × Orchiaceras bivonae (death.) Soó (Syn .: Orchis × bivonae death. ) = Orchis anthropophora × Orchis italica
  • × Orchiaceras meilsheimeri (Rouy) P. Fourn . (Syn .: Orchis × macra Lindl. ) = Orchis anthropophora × Orchis purpurea
  • × Orchiaceras spurium (Rchb. F.) EGCamus (Syn .: Orchis × spuria Rchb.f. ) = Orchis anthropophora × Orchis militaris
