Stem tall, 2—5 feet high, leafy. Leaves mostly orbicular in outline, 5—7-parted, the upper into narrow-cleft, laciniate divisions, petioled. Flowers nodding, less than an inch long, dull purple, bluish or occasionally white, numerous in an elongated spike; sepals 5, blue, ⅓ of an inch long, not spreading, the upper one prolonged into a spur, half an inch long; petals white, nearly as long as the sepals. Frequent in the region around Banff in open woods at the lower altitudes, flowering in July. [Sidenote: =Delphinium Menziesii= DC. _Blue Larkspur._] Sparingly leafy, 10—18 inches tall, from a tuberous rootstock. Leaves, the lowest round reniform, cut into irregular, oblong, obtuse lobes, the upper with linear, acute lobes. Flowers few in a simple panicle, sepals lanceolate, obtuse, ¾ of an inch or more long, spreading, brilliant blue, about as long as the short curved spur; petals exserted, white with purple veins. Throughout the region in open ground and on grassy slopes; flowering in early June or later according to the altitude. [Sidenote: =Actæa arguta= Nutt. _Western Red Baneberry._] Stems erect, 2—3 feet high, smooth except the inflorescence. Leaves large, ternately compound, the basal leaf long-petioled, the divisions long petioled and pinnate, leaflets ovate, 1½—5 inches long, cut with sharp teeth. Raceme ovoid, 1—2 inches long; flowers small, white, with petal-like sepals; petals, 4—10 spatulate and minute; stamens numerous; berries in a spreading raceme, small, spherical, and purplish red. Frequent in the rich woods throughout the region, at the lower altitudes; flowering in late May and early June. [Illustration: Delphinium Brownii Rydb. (½ Nat.) Mountain Larkspur.] [Illustration: Anemone globosa Nutt. (⅓ Nat.) Wind-Flower.] [Sidenote: =Actæa eburnea= Rydb. _Western White Baneberry._] Similar to the preceding species and often growing with it and difficult to distinguish from it when in flower: in fruit, however, they are quite distinct. In A. eburnea the berries are fully twice as large, nearly half an inch long and a quarter of an inch in diameter and pure waxy white. In rich moist woods throughout the Rockies; flowering with the other species in May and early June; fruiting in late July. BERBERIDACEÆ _Barberry Family_ Shrubs or herbs with alternate or basal leaves, with or without stipules, and solitary or racemed, mostly terminal flowers; sepals and petals generally overlapping in several series; stamens as many as the petals and opposite them; flowers perfect. [Sidenote: =Berberis aquifolium= Pursh. _Trailing Mahonia._] A smooth, trailing shrub. Leaves petioled, pinnate, leaflets 3—7, ovate or oval, oblique, obtuse, truncate or slightly cordate at the base, sessile thick, persistent, finely veiny, 1—2 inches long, with spine-bearing teeth. Flowers yellow, in several erect, dense, terminal racemes; berry globose, blue or purple.
