Psilon
A Psilon is a unit of length that is equal to 44 manly strides or, less precisely, 0.025 miles (a quarter of a tenth of a mile) or 40 meters. The Psilon is best known as the official unit of measurement during the censusing of plants in the genus ''Silene'' (see Silene) in a metapopulation surrounding Mountain Lake Biological Station in Giles County, Virginia.〔Thrall, P.H. & Antonovics, J.A. : "THEORETICAL AND EMPIRICAL-STUDIES OF METAPOPULATIONS - POPULATION AND GENETIC DYNAMICS OF THE SILENE-USTILAGO SYSTEM", pg S1249-S1258 . Canadian Journal of Botany, 1995.〕〔D.E. McCauley. (The Relative Contributions of Seed and Pollen Movement to the Local Genetic Structure of ''Silene alba'' ), pg 257-263. Journal of Heredity, 1997〕〔("Echoes", the MLBS Newsletter (Fall/Winter 2010) )〕 ---- Etymology: Derived from the Latin ''Silene.'' == See also ==
