2. COMMON NAME: Round-leaved orchis. 



3. FAMILY: Orchidaceae (Orchid Family). 



4. Genus: Orchis rotundifolia is one of 

 approximately 80 species in the genus. Most of 

 the species are native to the temperate to cooler 

 areas of the Old World, with 3 or 4 found in North 

 America (Hitchcock et ai. , 1969) . Orchis 

 rotundifolia is the only species knov/n from the 

 Pacific Northwest region. 



5. SPECIES: Orchis rotundifolia is the only member 

 of the genus in Montana (Dorn, 1984). In 1968, 

 Eric Hulten created the monotypic genus Amerorchis 

 to accommodate O. rotundifolia (Luer, 1975) . This 

 treatment is followed by Luer, and by Williams and 

 Williams (1983) . In agreeing with this taxonomic 

 outline Luer (1975) concludes that, in fact, no 

 true representatives of the genus Orchis occur in 

 North America. Orchis is used here in order to 

 match the nomenclature in the readily available 



-^ ■ ■ state and regional floras, that are likely to be 



\,) used by Bureau of Land Management personnel and 



others (Hitchcock et ai. , 1969; Dorn, 1984).
