Index to the genera and species of Hepaticae described by William Mitten

William Mitten (1819–1906) described 373 species of Hepaticae in 25 publications between 1851 and 1889. Most of Mitten's types are at NY, but original material of some species may be found at BM, FH, and G. This paper provides an index to the species and genera described by Mitten and a bibliography of papers in which his new hepatics were described. The index to species includes information on lectotypification, location of original or type material, and synonymy.
