Keys and Annotated Species Catalogue for Liverworts and Hornworts

William T. Doyle and Raymond E. Stotler
Madroño 53(2): 89-197. 2006

Part III is similar to the catalogue and key to the mosses; however, this work has the added feature of diagnostic narratives to separate species beyond the use of the keys. The work provides keys and identification narratives for the 150 liverworts and hornworts documented for California. Although written for California, it will be extremely useful for Nevada and southern Oregon.There are no liverworts or hornworts known from Nevada that are not in this work.
