Systematics
Order : Asparagales (Asparagales)
Family : Orchids (orchidaceae)
Subfamily : Orchidoideae
Tribe : Orchideae
Sub tribus : Orchidinae
Genre : Handelwurzen
Scientific name
Gymnadenia
R.Br.

The gymnadenia ( Gymnadenia ) are a genus of flowering plants in the family of orchids (Orchidaceae). The genus includes, including the species of the earlier genus Nigritella (cabbage florets), about 26 species. The genus Gymnadenia s. l. is Palearctic , from the Iberian Peninsula in the west to China, Korea and Japan in the east.

There is a scientific controversy within botany about the inclusion of the cabbage florets (known as the genus Nigritella ) in the genus Gymnadenia . While some researchers believe that both should be united in the genus Gymnadenia (as illustrated in this article), others argue that both are sister groups and could be maintained as separate genera.

Vegetative characteristics

Gymnadenia species grow terrestrially as perennial herbaceous plants of medium height. The relatively thick, fleshy tubers are divided in the shape of a hand, each with some slender, somewhat fleshy roots . The independently upright stem is slim to strong, stem -round, fleshy and glabrous.

The leaves are arranged alternately on the stem. The simple leaf blades are linear-ribbon-shaped to elliptical and the longitudinally folded blade base envelops the stem. Leaf sheaths are often present at the base of the stem.

Generative characteristics

Many flowers stand together in terminal, head-shaped to elongated, racemose inflorescences . There are few lanceolate, sterile bracts . The fertile bracts are shorter to slightly longer than the ovary.

The seated under constant ovary is usually turned slightly and thus are the flowers resupinat (in the species of the former genus Nigritella not rotated). The bald ovary is narrow-cylindrical or spindle-shaped. The relatively small to medium-sized, hermaphrodite flowers are zygomorphic and threefold. The cylindrical spur is often slightly curved and shorter or longer than the ovary, with a blunt or bilobed end. The bracts are pink to dark purple or rarely white. The central, concave sepal and the straight, lateral petals often curve together like a helmet; whereby the two petals are slightly shorter than the sepal. The two free, lateral sepals are mostly spread out and bent back. The lip ( labellum ) is broad-rhombic to obovate and simple to clearly three-lobed. The column is short. The upright anthers are elongated or egg-shaped and have two counters . There are two club-shaped pollinia . The relatively small to elongated rostellum (adhesive gland) is indistinctly three-lobed. The two relatively small staminodes are almost spherical and are located laterally at the base of the fertile anthers. The two very large scars are on the side of the base on each side of the column.

The capsule fruits are upright.

ecology

In Gymnadenia TYPES is tuber geophytes . There is an endotrophic orchid-type mycorrhiza .

Attractants and pollinators

In two species ( Mosquito-Haendelwurz and Fragrant Haendelwurz ) gas chromatography identified 45 and 44 volatile aromatic substances that attracted butterflies , of which 37 and 25 species could be identified. Benzyl acetate , eugenol and benzoic acid benzyl ester were recognized as attractants in the case of the mosquito-handelwort, benzyl acetate, benzaldehyde , phenylethanal , 1-phenyl-2,3-butanedione, phenylethyl acetate, eugenol and an unidentified component acted as attractants in the case of fragrant Handelwurz. The smell of the mosquito-handelwurz, spread in the distribution area of ​​the fragrant hendelwurz, could not attract pollinators for the mosquito-handelwurz. In a day-night rhythm , the examined flower types gave off different attracting aromas.

Systematics and distribution

The genus Gymnadenia was in 1813 by Robert Brown in Hortus Kewensis; or, a Catalog of the Plants Cultivated in the Royal Botanic Garden at Kew. London. , 2nd edition, Volume 5, pages 191, 197 prepared. Type species is Gymnadenia conopsea (L.) R.Br. The generic name Gymnadenia is derived from the Greek gymnos: naked and aden: gland (ie “naked gland”), it refers to the often exposed adhesive disc (Viscidium) in the flowers.

The genus Gymnadenia belongs to subtribe Orchidinae from the tribe Orchideae in the family of Orchidaceae . For a while it was assumed that the genus Gymnadenia was only closely related to the genus Nigritella (cabbage florets). But now the latter is mostly included in the former.

The genus Gymnadenia s. l. is Palearctic , widespread in the west from the Iberian Peninsula across Europe, West and Central Asia to China (five species, three of which are only there), Korea and Japan in the east. Some species are endemic and few species are widespread.
