Hepaticae Collected in Nevada by Elva Lawton in 1955

Contributions Toward a Bryoflora of Nevada: Bryophytes New for the Silver State

“…Bryophyte collections obtained by Baker and Nutting near Carson City in 1902 were subsequently published by Cardot and Theriot (1904). Nearly 50 years later the first catalogue of liverworts and mosses was published for the state of Nevada (Clark 1957;Lawton 1958). Lawton's collections obtained during a 1955 expedition to Nevada remained the largest collection of Nevada mosses for over the next 40 years comprised of 520 specimens obtained from 42 collecting sites within 12 of the 17 counties (Lawton 1958).…”

“…Additional historic herbarium specimens obtained by previous workers are the basis for the Lawton catalogue. A total of 25 liverworts (Clark 1957) and 144 mosses (Lawton 1958) were reported for Nevada. Since that time several other botanists have reported additional taxa as new to the Nevada bryoflora (Lavin 1981(Lavin , 1982Rust and Lavin 1986;Heise 2000;Stark and Whittemore 2000;Stark et al 2002).…”

“…has P. cordeana and another with P. roellii, all of the Lawton Nevada liverwort collections were originally examined by Clark, and she determined Lawton 3053 as P. roellii prior to distribution of duplicates. This record of Porella roellii in Nevada was cited as Lawton 3055 inClark (1957); however, the correct collection number is in fact Lawton 3053.Lawton 3055 is a collection of Dicranoweisia. Carson City Co.: Voltaire Canyon north of Highway 50, Carson Range, northern Sierra Nevada, Toiyabe National Forest, Shevock 21948 (CAS, MO, UC, UNLV) and below Secret Harbor Vista Point off of Highway 28, Lake Tahoe Basin Management Unit, Shevock 22038 (CAS, UC, UNLV) [confirmed by Dan Norris].…”

Bryophytes of riparian areas in the Toiyabe Range of Central Nevada

“…The state of Nevada remains one of the least surveyed regions for bryophytes in the Intermountain West. In spite of this a number of investigators have worked in the region (Watson 1871;Cardot & Theriot 1904;Clark 1957;Lawton 1958;Flowers 1973;Mozingo 1976;Lavin 1981Lavin , 1982Whittemore 1994;Eckel 1996;Stark & Whittemore in press). In addition, Spence (1988) summarized the moss flora of the Intermountain region, which included the entire state of Nevada.…”
