Dactylorhiza

Dactylorhiza is a genus of flowering plants in the orchid family Orchidaceae. Its species are commonly called marsh orchids or spotted orchids,[2]Dactylorhiza were previously classified under Orchis which has two round tubers.[3]

Description

They are hardy tuberous geophytes. In a thickened underground stem, they can store a large amount of water to survive arid conditions. The tuber is flattened and finger-like. The long leaves are lanceolate and, in most species, also speckled. They grow along a rather long stem which reaches a height of 70–90 cm (28–35 in). Leaves higher on the stem are shorter than leaves lower on the stem. The inflorescence, compared to the length of the plant, is rather short. It consists of a compact raceme with 25-50 flowers. These develop from axillary buds. The dominant colors are white and all shades of pink to red, sprinkled with darker speckles.

Taxonomy

Etymology

The name Dactylorhiza is derived from Greek words δάκτυλος "daktylos" (finger) and ρίζα "rhiza" (root), referring to the palmately two- to five-lobed tubers of this genus.

Species
Dactylorhiza cordigera ssp. pindica
Dactylorhiza incarnata nothosubsp. versicolor
Dactylorhiza russowii
Elder-flowered orchid
(Dactylorhiza sambucina)

Many species in this genus hybridise so readily that species boundaries themselves are vague (but see[4]), with regular name changes and no clear answers. A few species colonise very well onto fresh industrial wastes such as pulverised fuel ash, where vast hybrid swarms can appear for a decade or more, before ecological succession replaces them.

Distribution and habitat

These terrestrial orchids grow in basic soils in wet meadows, bogs, heathland and in areas sparsely populated by trees. They are distributed throughout the subarctic and temperate northern hemisphere. It is found across much of Europe, North Africa and Asia from Portugal and Iceland to Taiwan and Kamchatka, including Russia, Japan, China, Central Asia, the Middle East, Ukraine, Scandinavia, Germany, Poland, Italy, France, the United Kingdom, etc. Inclusion of the widespread frog orchid, often called Coeloglossum viride, into Dactylorhiza as per some recent classifications,[7][8] expands the genus distribution to include Canada and much of the United States.[1]
