Additions to the Hepaticae of New Mexico

Abstract

Eight species are reported as new to the hepatic flora of New Mexico, bringing the number of liverworts known from the state to 52. Only 44 species of liverworts have previously been reported from New Mexico, most from the mountainous northeastern part. Considering the vast area of the state in which climatic and topographical conditions favor the growth of these plants, the small number presently recorded underscores the need for additional collecting. Initially eight species were reported over 100 years ago from collections made by Fendler near Santa Fe (Sullivant, 1849-50). Five species were added from the mountains of central and northeastern New Mexico early in this century (Standley, 1915). In the following year five more species were added (Standley, 1916), and later 18 additional species were reported from collections in the area of Santa Fe and Las Vegas (Arshne, 1933). Finally, an additional ten species were determined from an Arshne collection in the herbarium of New Mexico Highlands University (Shields, 1954). Shield's paper gives a complete listing of the species reported to the present 1 Department of Biology, Texas Technological College, Lubbock, Texas 79409.

However, duplications found in the various reports result in a total of 44 species from the state to that time (Bird, 1963). From my collections from eastern New Mexico, three species are added to the list by this report. Also, in the spring of this year a number of collections by the late R. A. Studhalter and by John Marr made in 1936 were found stored in the Biology Department at Texas Technological College. Included in these collections were five more previously unreported species for the state; the specimens were determined by me. The addition of these eight species raises the total of New Mexico Hepaticae to 52. The collections are deposited in the Reed Herbarium at Texas Technological College as well as in my personal collection. Jamesoniella autumnalis (DC.) Steph.
