along climatic, chemical, and physical gradients in peat lands of western Canada. -Nova Hedwigia 53: 27-7 1. Abstract: The bryophyte component of peat land veget ation is analysed for 395 stands on 335 study sites in western Canada. Sites are located along a broad transect from the Queen Charlotte Islands, British Columbia to southeastern Manitoba. The climate in the study area is divided into five zones : hyper­ oceanic, oceanic , suboceanic, subcont inental. A TWINSPAN anl separated the stands into six groups and selected indicator species for each group. A DCCA ordination showed that surf ace water che­
