Introduction

All collections forming the basis of this checklist have been examined through herbarium studies by the first author unless the locality cited is followed by a literature citation in parenthesis. The checklist is incomplete but will serve as a basis for the distribution of liverworts and hornworts in the Interior Highlands, and as a basis for future studies and reference.

Literature citations for specimens not seen by us are included in the Literature Cited. Additional literature pertaining to the liverwort and hornwort flora of the Interior Highlands follow the literature cited. Voucher specimens, or references to herbaria where voucher specimens are deposited, are filed under the appropriate taxon in the bryophyte collections at the Ozark Regional Herbarium, Missouri State University (Missouri State) or The Missouri Botanical Garden (MO). Specimens deposited in other herbaria are parenthetical following the county. They include DUKE (Duke University), KSP (Pittsburg State University), SIU (Southern Illinois University), UARK (University of Arkansas, Fayetteville), and UMO (University of Missouri, Columbia). Except where noted, nomenclature and the arrangement of families follows Stotler and Crandall-Stotler (1977).

Physiographic Regions of Study Site in the Interior Highlands of North America

In Fig. 1 Counties located in the Interior Highlands are divided into approximate geographic regions, i. e., the Salem Plateau (SALEM PLATEAU:), the Springfield Plateau (SPFD PLATEAU), the St. Francois Mountains (ST FRANCOIS MTS), the Ozark Hills (OZARK HILLS:), the Boston Mountains (BOSTON MTS), the Arkansas Valley (ARKANSAS VALLEY), and the Ouachita Mountains OUACHITA MTS). For the Springfield and Salem Plateaus and the Mississippi lowlands, counties in Arkansas or Oklahoma are designated by "-AR" or "-OK" respectively. For the Boston Mountains, the Arkansas Valley, and the Ouachita Mountains, counties in Oklahoma are designated by "-OK." The distribution of taxa in areas immediately adjacent to the Interior Highlands, the Unglaciated Prairie (PRAIRIE), Border Counties (BORDER COUNTIES) north of the Missouri River, the Mississippi Lowlands (MISSISSIPPI LOWLANDS), and the Coastal Plain COASTAL PLAIN, are also noted.
