Moss

Mosses are the second most speciose group of plants, after the enormously richer angiosperms. A Checklist of Mosses lists 12,800 recognized species in 901 genera, including 42 synonymous genera with species that have not been transferred to the accepted genus. Each listed species is qualified using a four-level ranking system that indicates our level of knowledge about the species. Each in the highest three levels is supported by at least one citation from a bibliography of 1,756 references published since 1962, the closing date for the last comprehensive list of mosses, Index Muscorum. While about 44% of the species fall into the highest rank, about 42% fall into the lowest, indicating there is ample opportunity for basic taxonomic work to be done on the mosses. This prospectus includes the Introduction to the Checklist, sample pages from it, and a list of the Checklist's genera, with the number of species and family placement indicated for each.

The Checklist, which is updated regularly (last update version February 2000), will be available on the web (the address is in the Introduction), and xerographic, strip-bound copies, about 300 pages, may be obtained, at cost plus shipping ($20.00), from the authors.
