HOME SPECIES INDEX GENUS INDEX GLOSSARY
Nardia 1b more than 1 oil body per cell > Nardia 2a oil bodies glistening > Nardia 3a leaves bilobed > Nardia japonica
Synonyms: None.
Special Status: ORBIC List 2.
Recognition: Notched leaves, glistening oilbodies, and clearly developed underleaves characterize this species. It is rather small compared to the other species of the genus.
Distribution: Grows on soil at high elevations in the mountains. In Oregon known from the Three Sisters Wilderness and Mt. Hood. First reported as new to North America from British Columbia and Alaska by J. Godfrey (1980. The Bryologist 83: 224-228).
Comments: Although presently known from very few sites, I predict that this species will prove to be fairly common in Oregon and Washington as alpine zones are explored for liverworts.
