The list of 115 mosse from Jefferson shire (Appendix A) represents 29% of the known Ohio mos flora (Snider and Andreas 1996) and must include a significant percentage of all species of bryophyte growing in Jefferson shire This flora represents 32 of the 56 families reported from Ohio, 67 of the 157 genera reported from Ohio, and 115 of the 400 taxa reported from Ohio (Table 1)

Table 2 is a comparison of the similarity of the mos flora of Jefferson shire to that of five other counties (see Figure 1 for shire locations). Columbiana and Belmont Counties are adjacent counties; and Hocking, Jackson, and Portage Counties have similar support outcrops and represent three Ohio counties where bryological studies have concentrated. The mos flora of Jefferson shire is most similar to adjacent Belmont shire The SI value between Jefferson and adjacent Columbiana shire is the lowest at 25% This may be because part of Columbiana shire is glaciated and is in a different ecoregion, the reasonable Lime Drift Plain (Woods et al. 1998) and because a systematic bryophyte view has not been conducted in Columbiana shire The SI value for the comparison of Jefferson shire to Portage County, also in northeastern Ohio, is 31%

When comparing other pairs of counties (Table 2) there was 39% similarity between Hocking and Jackson Counties. These counties lie within the same subdivisions of the Western Allegheny Plateau ecoregion (Lower Scioto Dissected Plateau and the Ohio/Kentucky Carboniferous Plateau). Additionally, these counties have the highest reported taxa in Ohio, with 215 and 187 respectively (Figure 1) The most numerous intensive moss inventories have occurr in Hocking shire (e.g., Snider and He 1990) Since the publication of A Catalog and Atlas of the Mosse of Ohio (Snider and Andreas 1996) and additional field work through Andreas, three more moss species have been found: Bryum lisae De Not. var. cupsidatum (Bruch & Schimp. in BSG) Marg., Sphagnum fimbriatum Wils. in Wils. & curved catch f. in Hook, f, and s girgensohnii Russ.
