Dactylorhiza maculata , известная как змеиная Орхида Хит [ 2 ] Или пятничная орхидея в верестой , является травянистым многолетним растением семейства Orchidaceae . Он широко распространен в горных регионах по всей Европе от Португалии и Исландии на восток до России. Это также встречается в Алжире, Марокко и Западной Сибирии. [ 1 ] [ 3 ]
Этимология
[ редактировать ]Название рода Dactylorhiza образуется из греческих слов Δάκτυλος 'daktylos' означает «пальцем» и ρίζα 'Ridza', что означает «корень» и относится к клубням этого растения, которые разделены на несколько туберкульсов. Конкретный эпитет «maculata», означающий «пятнистый», относится к окрашенным листьям. Научное биномиальное название этого растения было изначально Orchis Maculata , предложенным шведским натуралистом и ботанистом Карлом Линнеусом в 1753 году. Название было изменено в настоящее время ( Dactylorhiza maculata ) венчарским ботанистом Кароли Резас так Растение называется Geflecktes knabenkraut , во французских орхисах , а в итальянском орхиде Macchiata или Erba d'Adamo .
Description
[edit]
Dactylorhiza maculata are usually 15–45 centimetres (5.9–17.7 in) in height, with a maximum of 70 centimetres (28 in). These plants are bulbous geophytes, forming their buds in underground tubers or bulbs, organs that annually produce new stems, leaves and flowers. Furthermore these orchids are terrestrial: unlike epiphytes they do not live on other large plants.
This orchid has an erect, glabrous and cylindrical stem, with a streaked surface. The leaves are oblong or oval-lanceolate, with dark ellipsoid-shaped spots on the surface (hence the species name). The leaves are amplexicaul and can be either radical (basal) or cauline.
The underground part of the stem has two webbed tubers, each deeply divided into several lobes or tubercles (characteristic of the genus Dactylorhiza). The first one has the important function of supplying the stem whilst the second collects nutrients for the development of the plant that will form in the coming year.[citation needed]
The inflorescence is 5–15 centimetres (2.0–5.9 in) long and it is composed of flowers gathered in dense spikes. The flowers grow in the axils of bracts membranous and lanceolate-shaped. Their colours vary from light pink to purple or white with darker streaks mainly on the labellum (sometimes at the margins of tepals). The flowers reach on average 10–15 centimetres (3.9–5.9 in). The flowers are hermaphrodite and insect pollinated.
Habitat
[edit]The heath spotted orchid prefers sunny places on lowlands or hills. It can be found in slightly damp meadows but also in the undergrowth of dry forests, in areas with bushes and at the edges of streams. It grows on siliceous and calcareous substrate, at elevations up to 2,200 metres (7,200 ft) above sea level.
Ecology
[edit]Orchids in the genus Dactylorhiza are mycorrhizal generalists. D. maculata has been found to form associations with a range of common species of mycorrhizal fungi in the Tulasnellaceae, as well as with species in the Ceratobasidiaceae and Sebacinales.[4][5]
Dactylorhiza maculata is pollinated by insects, especially bumblebees. The flowers are 'food deceptive', i.e. do not provide nectar for their pollinators.[6]
Subspecies
[edit]Many names have been proposed for species and varieties in the species. As of September 2024, the following subspecies are accepted:[7]
- Dactylorhiza maculata subsp. fuchsii (Druce) Hyl. – Europe to Siberia and Mongolia
- Dactylorhiza maculata subsp. maculata (L.) Soó – Europe to Siberia
- Dactylorhiza maculata subsp. maurusia (Emb. & Maire) Soó – Morocco and northern Algeria
- Dactylorhiza maculata subsp. saccifera (Brongn.) Diklic – southern Europe and Turkey
- Dactylorhiza maculata subsp. sooana Borsos ex Batoušek – Slovakia
- Dactylorhiza maculata nothosubsp. transiens (Druce) M.H.J.van der Meer (D. maculata subsp. fuchsii × D. maculata subsp. maculata) – Germany, France, Spain, Great Britain, and Ireland
Inter-species hybrids
[edit]Inter-species hybrids include:
- Dactylorhiza × kerneriorum nothosubsp. kerneriorum (syn. Dactylorhiza × ruthei (M.Schulze ex Ruthe) Soó) (D. incarnata subsp. incarnata × D. maculata subsp. fuchsii) – Spain, France, Great Britain and Ireland, middle Europe, Romania, and East European Russia)[8]
