Excerpt from The Musci and Hepaticae of the United States East of the Mississippi River: Contributed to the Second Edition of Gray's Manual of Botany The following pages are designed to contain brief descriptions of all the Musci and Hepaticae hitherto detected in that portion of the United States lying east of the Mississippi River. A few species found elsewhere, either new, or having a geographical range heretofore unnoticed, or for some other special reason, have also been described; namely, those from Texas and New Mexico, and also several from near our northern boundary, and likely to occur within it. The territory within the limits adopted - extending, as it does, from 25 to 47 North Latitude, and traversed for nearly its entire length by mountain ranges, reaching, at several points in their northern and southern terminations, an alpine elevation - presents conditions favorable to a copious and varied muscological vegetation. And if the number of species here recorded is not so large as that found in an equal area similarly situated on the Eastern Continent, it must be borne in mind that our Bryology and Hepaticology (particularly the latter) have thus far been very imperfectly investigated. Scarcely any portion of our country, excepting Central Ohio, has been carefully examined. The mountain ranges have only been cursorily visited by a few interested in these branches of Botany.
