Version 1 December 2017

  1. Commons, Alexander (1829 in Chester County, Pennsylvania - 1919): - Collections from 1885 - 1896, see Dix (1961: 371). "Alecander Commons was born in Pennsylvania, but did most of his collecting in Delaware. According to Harshberger's Botanists of Philadelphia he was largely self-educated on account of ill health and became interested in botany from reading his brother's copy of Darlington's "Florula Cestrica". He had a collection of "nearly 3000 species listed, of mosses over 60 species, hepatics 40 species, lichens 160 species, and of fungi 1300 species." His collection of plants was given to the Academy of Natural Sciences of Philadelphia." (Dix 1961: 371)
