Dactylorhiza fuchsii, the common spotted orchid, is a common species of orchid. It is widespread across much of Europe, with the range extending eastward into Siberia, Mongolia and Xinjiang. The species is also reportedly naturalised in the Canadian Province of Ontario.[1][2][3][4][5][6]


Dactylorhiza fuchsii is widely variable in colour and height, ranging from 15 to 60 cm in height. The dense and rich-flowered inflorescence (flower spike), produced in June–August, is at first conical then cylindrical. The flower colour can vary from white to pale purple with purple spots, a symmetrical pattern of dark purple loops or dots and dashes. The lip has three lobes. The bracts are usually shorter than the flower. The lip is smaller than that of the very similar Dactylorhiza maculata and has three deeper cuts. The middle lobe is more than half as large as a lateral lobe. Some colonies are highly perfumed, attractive to day-flying moths. The leaves are narrow lanceolate, keeled and often dark-spotted.

Identification[edit]

The orchids that are most similar belong to the Dactylorhiza maculata group. D. maculata ssp. maculata is distinguished by having the lip less deeply trilobed, while D. maculata subsp. saccifera has one spur large and saccular (sac-shaped) and the bracts of the inflorescence as long as or longer than the flowers. Outside of the "maculata group", D. majalis is very similar to D. fuchsii, but is distinguished by the following characters: the spots of the leaves are less elongated, the bracts of the inflorescence are longer and the lower transcend the inflorescence itself; it tends to be less cylindrical (a little more 'globular'), the stem is hollow (not solid) and the leaves are slightly larger. Other similar orchids are D. incarnata and D. lapponica. These stand out as the habitat is quite different (fens and bogs) and in any case the stem is hollow.

Distribution and habitat[edit]

D. fuchsii is a Eurosiberian species occurring over Europe from Ireland in the west eastwards to Mongolia, the Altai Mountains and across northern Asia.[7] It is sympatric with D. maculata.

Typical habitats are, variously across the range, conifer, beech and chestnut forests, moderately wet meadows, bogs and margins of streams. The preferred substrate is supposedly calcareous although it seems not to be particularly linked to this type of substrate. In mountain, subalpine and alpine ecosystems D. fuchsii is found from 900 to 2300 m above sea level. Elsewhere it is found from sea level.

The full list of areas (World Geographical Scheme for Recording Plant Distributions) for D. fuchsii is Finland, Great Britain, Iceland, Ireland, Norway, Sweden, Austria, Belgium, Czechoslovakia, Germany, Hungary, Netherlands, Poland, Switzerland, Corse, Italy. Romania, Yugoslavia, Belarus, Baltic States, Central European Russia, East European Russia, North European Russia, South European Russia, Northwest European Russia, Ukraine, Altay, Buryatiya, Chita, Irkutsk, Krasnoyarsk, Tuva, West Siberia, Yakutiya, Xinjiang, Mongolia.

In Italy it is found mainly in the Alps in the northern Apennines. In Britain it is widespread, the most common orchid, occurring from alkaline marshes to chalk downland. After the bee orchid, Ophrys apifera, it is the most successful orchid coloniser of waste land.

Taxonomy[edit]

This plant belongs to a problematic group of orchids. D. fuchsii is very variable in flower colour and flower morphology, plant height and the scent of flowers. This is due to the ease of introgression (the transfer of genetic material from one sympatric species to another, only partially isolated from the first, through interspecific hybridization and repeated backcrossing to a parental species), the ability of these plants to adapt quickly and easily to habitat and different substrates and possibly other causes. As a result, a multitude of forms have been defined for this plant. The World Checklist of Kew Gardens lists over 25 varieties, of which 7 are recognized as valid.[7]

Hybrids[edit]

Hybrid between D. fuchsii and Gymnadenia conopsea

Hybrids with other species of the same genus are frequent. These include:

This plant hybridizes easily with species of different genera (intergeneric hybridization). The list below shows some of these intergeneric hybrids (these hybrids are not always recognized by all botanists):

Etymology[edit]

The specific name honours the German scholar Leonhart Fuchs.
