Remarkable
extensions of upper elevation limits for 37 species and one variety of mosses
in North America are reported from Wyoming, U.S.A. The bryophyte inventory
research was conducted in the two national forests in the state, Medicine Bow
and Shoshone National Forests, lying in the high country of the Rocky
Mountains. The study area spans about 13700 km2 and ranges in elevation from approx. 1700 to
over 3650 m. A total of 13 families in the author’s herbarium, collected within
the period of 2003-2014, were analyzed, namely Amblystegiaceae,
Bartramiaceae, Brachytheciaceae,
Calliergonaceae, Dicranaceae,
Hedwigiaceae, Hypnaceae, Mniaceae, Plagiotheciaceae, Polytrichaceae, Pottiaceae, Scouleriaceae and Sphagnaceae. Selected
specimens are cited representing taxa from the
highest known elevations of Wyoming. The new information, supplemented by
earlier works of the U.S. Rocky Mountains moss flora researchers, essentially
updates altitudinal ranges of the taxa, provided in
the recently published Volumes 27 & 28 of the Flora of North America.
