In springy ground and wet alpine meadows throughout the region, often growing in such abundance as to make the meadows brilliant with the blue and white flowers, which appear soon after the snow has left the ground in June and July. [Sidenote: =Trollius albiflorus= (A. Gray.) Rydb. _Western Globe-flower._] Stem erect, 6—12 inches high, more or less branching. Leaves palmately divided, the segments many cleft. Flowers solitary, 1—1½ inches broad, subtended by a whorl of leaves; sepals broadly obovate 5—6, pure white tinged on the back with greenish rose; petals 15—20, less than ¼ of an inch long, narrowly truncate, bright yellow, nearly concealed by the numerous stamens. One of the most abundant and conspicuous of the spring flowers of the alpine meadows, and marshy borders of alpine streams and lakes, commencing to flower when but a few inches high on the edges of the melting snow in May and June. [Illustration: _a_ Caltha leptosepala Hook. _b_ Trollius albiflorus (A. Gray) Rydb. Western Globe-Flower. (⅔ Nat.)] [Sidenote: =Aquilegia brevistyla= Hook. _Small Blue Columbine._] One to two feet high, slender, sparingly branched. Leaves, the basal long-petioled, biternate, lobed and crenate, the stem leaves few, nearly sessile and lobed. Flowers ½ an inch or more long, nodding, sepals blue, petals creamy-white with a short blue spur not more than ¼ of an inch long; styles and stamens hardly exceeding the petals. In open rocky situations, rather local, common in the region around Banff, flowering in May and June. [Sidenote: =Aquilegia flavescens= S. Wats. _Yellow Columbine._] Stems smooth, 1—3 feet high, branched. Leaves ternate, leaflets round-cordate, 3-parted, the segments coarsely toothed, 2—3-cleft. Flowers yellow, an inch or more long, nodding; sepals reflexed, oblong-ovate, acute, longer than the spurs; petals spreading with a spur half an inch long; styles and stamens nearly equal, much exserted. The commonest columbine throughout the region, growing in woods and on slopes up to 8000 feet, varying greatly in colour; flowering in June and July according to the elevation. [Sidenote: =Aquilegia formosa= Fisch. _Western Columbine._] Stem 2—4 feet high, branching, sparingly pubescent with spreading hairs. Leaves, the lower triternately parted on long petioles, the upper sessile and ternate or reduced to simple bracts, leaflets broadly wedge-shaped, 3-cleft. Flowers scarlet, drooping, more than an inch long; sepals scarlet varying to orange, spreading or reflexed, an inch long, lanceolate, acute; petals yellow, more or less spreading, with a scarlet spur about the length of the sepals; styles and stamens exserted. Throughout the Selkirks, in moist ground, on slopes and borders of rocky alpine streams, flowering during July and late June. [Illustration: _a_ Aquilegia flavescens S. Wats.
