Bibliography: p. 207-220. ... : The study area is the alpine zone of Wilcox Pass, Jasper National Park. The vascular flora consists of 186 species. A hybrid analysis of Dryas octopetala and integrifolia populations shows that a large percentage of them have intermediate characteristics; most of them more closely resembling E. integrifolia. Twelve community-types were found to be the most common in the study are. The Salix glauca and the Arctostaphylos uva-ursi community-types are typical of the lower alpine subzone. The other plant associations occur commonly in the middle alpine subzone: the Kobresia myosuroides and the Dryas octopetala associations on dry, exposed, snow-free ridges and hilltops; the Cassiope tetragona., the Salix nivalis and the Fhyllcdoce glanduliflora. associations in intermediate habitats; the Anten..'1aria lanata, the Carex nigricans and the Salix arctica community-types on moist, snowbed sites; and the Salix barra.ttiana and the Carex aqua.tills community-types in areas which are very wet and covered with deep snow. ...
