藓类四种，均属藓属；肝炎1种；16种地衣组成了不列颠哥伦比亚省西部某些地区的叶面苔藓植物和地衣区系。这是北美洲，美国东南部热带和亚热带地区北部的第一次报道叶面苔藓和肝。本文讨论了赤藓属四种植物的分类学，并给出了分种的关键。所有已经发现的物种，除了可能在北美西北部的零星地区，都是叶上的并生小叶物种，只有在北美西北部地区才有。地衣的两个分类群，花青衣（catilaria bouteillei）Zahlbr。和天竺鼠(Del；（原杜比）W.卡尔布。& C.库伯。（perlatolic acid strain）是加拿大的新菌株。
Four species of mosses, all in the genus Orthotrichum; 1 species of hepatics; and 16 species of lichens compose the foliicolous bryophyte and lichen flora of Thuja plicata L. leaves in certain areas of western British Columbia. This is the first report of foliicolous mosses and hepatics for North America, north of the tropical and subtropical regions of the southeastern United States. The taxonomy of the four species of Orthotrichum is discussed and a key given differentiating the species.All of the species that have been found on Thuja leaves except perhaps Catillaria bouteillei are facultative foliicolous species and occur on leaves, only in scattered areas of northwestern North America. Two taxa of lichens, Catillaria bouteillei (Desm.) Zahlbr. and Cetrelia cetrarioides (Del. ex Duby) W. Culb. & C. Culb. (perlatolic acid strain) are reported as new to Canada.
