Fam.  ORCHIDACEAE

Genus Dactylorhiza Necker ex Nevski, (1937)

Fam:   Orchidaceae Lindl.
Genus:  Dactylorhiza Necker ex Nevski, (1937)
English Name: Marsh orchid or Spotted


Description:

These are perennial herbaceous plants. Species of the genus Dactylorhiza - Marsh orchid or Spotted orchid are morphologically similar to species of the genus Orchis. For example in "Flora of NR Bulgaria", Volume II, BAS (1964), species of the genus Dactylorhiza are listed in the genus Orchis. The distinguishing feature is the form of tubers. Tubers of species of the genus Dactylorhiza are like palm composed of visible shares, while the tubers of species of the genus Orchis intact
Bracts of species of the genus Dactylorhiza are larger, ribbon and green with lying veins. Bracts of species of the genus Orchis transparent or colored, but not green, and the fibers are arranged parallel to them
Genus Dactylorhiza is presenterd by 8 species in Bulgaria, 2 of which are protected by Законодателство на Република България: Закон за биологичното разнообразие

Dactylorhiza (as named by Necker ex Nevski, 1937), commonly called marsh orchid or spotted orchid,[2] is a genus of flowering plants in the orchid family (Orchidaceae). 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.
Many species in this genus hybridise so readily that species boundaries themselves are vague, 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.
