North Pacific Coast Region This region extends along the coast from Vancouver Island north to southeastern Alaska (Figure 2). The seven taxa in this region are likely associated with coastal glacial refugia since most of their range was glaciated. Taxa in this group are Fern-leaved Goldthread (Coptis asplenifolia Salisb.), Lance-fruited Draba (Draba lonchocarpa var. vestita Schulz*), Swamp Gentian (Gentiana dou- glasiana Bong.), Bird's-beak Lousewort (Pedicularis ornithorhyncha Benth.), Alaska Holly Fern {Polystichum setigerum [K. Presl] K. Presl.*), Cooley's Buttercup (Ranunculus cooleyae Vasey & Rose), Menzies' Burnet (Sanguisorba menziesii Rydb.*). 7. Northern Rocky Mountain Region The taxa in this region range north (from about 52°N) in the Rocky Mountains of southern Alberta and British Columbia to southeastern Yukon and southwestern Northwest Territories (Figure 2). The three taxa in this group are Boreal Paintbrush (Castilleja fulva Pennell*), Jordal's Locoweed {Oxytropis jordalii Porsild ssp. davisii [Welsh] Elisens & Packer*) and Raup's Willow (Salix raupii Argus*). Castilleja fulva also has a single disjunct station in the southwestern Yukon. 8. Cascade Mountains-Rocky Mountains Regions This region ranges from the Cascade Mountains of southern British Columbia and northern Washington to the Rocky Mountains of southern British Columbia, southern Alberta and northern Montana (Figure 2). Five taxa are included in this range: Timber Milk-vetch (Astragalus miser Dougl. vars. miser and serotinus [Gray ex Cooper] Barneby), Deer Paintbrush (Castilleja cervina G
