What is "coeloglossum"

Coeloglossum is a genus of orchid. It has long been considered to have only one species, Coeloglossum viride, the frog orchid. Some recent classifications regard Coeloglossum as part of the larger genus, Dactylorhiza, so that C. viride becomes Dactylorhiza viridis. Other sources continue to keep Coeloglossum viride separate.

Under either name, the species has a wide distribution across the cooler parts of the Northern Hemisphere, covering much of Europe, non-tropical Asia ( Russia, Japan, China, the Himalayas, etc.), much of Canada and parts of the United States ( Alaska, Northeast, the Appalachians, Great Lakes Region, Northern Great Plains, and Rocky Mountains). It is typically found growing in moist, rich soil in wet meadows, moist or wet deciduous woods and thickets, and is frequently found on steep slopes.
