The '''Frog Orchid''', or '''''Coeloglossum viride''''', also known as the '''Long-Bracted Green Orchid '''and '''''Dactylorhiza viridis''''' is a monotypic [[genus]] of the family ''[[Orchidaceae]]'' generally found within the [[palearctic]] [[ecozone]] <ref>(L.) R.M. Bateman, Pridgeon & M.W. Chase 1997)</ref> throughout the mid to northern United States through Canada, and in the British Isles and parts of Western Europe.<!-- could not find specific range in Europe? --> It is typically found growing in moist, rich soil in wet meadows, moist or wet [[deciduous]] woods and thickets<ref>http://www.npwrc.usgs.gov/resource/plants/vascplnt/species/coel.htm</ref>, and is frequently found on steep slopes.
The generic name is derived from the Greek ''koilos glossum'' meaning "hollow tongue," referring to the hollow spur on the tongue-like [[labellum]]<ref>http://www.botany.wisc.edu/orchids/Coeloglossum.html</ref>.
Plant arises from fleshy, forked roots and ranges in height from 10-55 cm.
Leaves of the Frog Orchid are 5-14 cm long and 2-7 cm wide; leaves at the base of the orchid are [[obovate]] to [[elliptical]], while leaves higher on the stem become [[lanceolate]]. Two to six leaves are found one one plant, and leafing is alternate.
[[Inflorescence]] of the orchid is a dense [[raceme|spike-like cluster]] containing 7 to 70 small flowers. Flowers are greenish in color, and often tinged with purple, reddish, or red-brown color. Flowers are subtended by conspicuous long, tapering [[bracts]] which are 1-6 cm long, with the lower [[bracts]] longer and typically greatly exceeding the length of the flower. [[Sepals]] are oval with little or no point, 3-7 mm long and 2-4 mm wide and dark green. Sepals join with petals to form a hood opposite the [[labellum|lower petal]] of the flower. Petals are long and narrow, 3.5-5 mm long and about 0.5 mm wide, and curve inwards. The [[labellum|lower petal]] is strap-shaped and usually split at the very tip to form two or three tooth-like divisions, with the middle tooth smaller than the others. It is 5-11 mm long and 1-4 mm wide. A 2-3 mm long nectar spur projects behind the labellum.

The Frog Orchid flowers in late May and early June. It is either pollinated by bees and small wasps, or reproduces autogamously by [[incoherent pollenia]]. <ref>http://www.botany.wisc.edu/orchids/Coeloglossum.html</ref>
The Frog Orchid can be mistaken for the Pale Green Orchid, but can be best distinguished by the labellum, which is notched at the apex and does not have the [[tubercle]] of the Pale Green Orchid.
