This study was done in Cerro Bandera, Puerto Williams (55°S) Chile. Vascular plants and mosses of the study area were identified. The distribution patterns of the vascular plants and mosses among a northern and southern slope and among microhabitats were assessed. A total of 52 species were identified, of which 34 were mosses and 18 were vascular plants. Also the microhabitats preferences were very different between mosses and vascular plants.
