The duration of flowering is 16 to 20 days longer for Long-stalked Starwort, Stellaria longipes Goldie, in this site. Some exceptions to this general trend are evident. Flowering occurs latest in site B (14 to 20 days) for Alpine Goldenrod, Solidago multiradi- ata Ait, Showy Jacob's Ladder, Polemonium pulcherrimum Hook, and Trisetum spicatum, and latest in site A (10 to 12 days) for Little-flowered Pentstemon, Pentstemon procerus Dougl. Seed dispersal of Payson's Whitlow Grass, Draba paysonii Macbr., occurs 10 days earlier in north- facing sites (A and C2) than in south-facing sites (B and F2), while Moss Campion, Silene acaulis L., begins seed dispersal 10 days earlier in F2 than in C2. Carex scirpoidea sites (D3 and ): In general, species begin phenological phases earlier in D3 (S02°E) than in E2 (NI6°W), or at.
