Abstract

The bryogeographical knowledge of insular Newfoundland has been significantly augmented through the intensive investigation of the bryoflora of Cataracts Provincial Park, Avalon Peninsula, and its vicinity. -- The area investigated included forested areas, bog, heath, and a deep, angular, and narrow river gorge and waterfalls which provide numerous microhabitats particularly suitable for growth of bryophytes. Each bryophyte habitat is fully described, and an annotated list of species gives data on occurrence, frequency, and fertility. Within an area of approximately 13 hectares, 121 species of mosses and 63 species of liverworts were collected, representing one third of the total known bryophyte flora of the island of Newfoundland. The mosses Bryum creberrimum and Ditrichum lineare and the liverwort Cephaloziella hampeana ane reported for the first time from insular Newfoundland. The ranges of a number of Newfoundland bryophytes, including several species previously thought to be more or less restricted to the predominantly calcareous regions of the west coast such as Hygrohypnum luridum or Lophozia gillmani, have been extended to include the Avalon Peninsula. -- A small southern element, represented by Sematophyllum marylandicum, and a northern element, represented by Lophozia bantriensis, are present within the Park but most of the moss and liverwort species there are typical circumboreal species.
