Data Set from “Genera of the Pottiaceae: Mosses of Harsh Environments”

by R. H. Zander

Home

 

This data set contains morphological information on the 76 genera of the Pottiaceae, and on ten (fully capitalized) non-pottiaceous genera used as outgroups in analysis. A dash (“-”) indicates a character that is variable in state or otherwise “unknown, undefined, or missing” (Farris 1988). There are 86 taxa and 75 characters; the first character is numbered as character “0”.

The character states scored for the data set are listed below; (R) = reduction-related character, of which there are 22 and weighted lower than other characters in most cladograms, (0´) = character not used at all in Cladogram 15 (i.e., not phylogenetically informative), (1´) = character occurred once in Cladogram 15 (i.e. phylogenetically very informative), and * = the hypothesized plesiotypic character state for the Pottiaceae. Character numbers correspond to those in the data matrix used with Hennig86, and begin with zero.
