Sparingly pubescent, with long whitish hairs, especially at the involucre, 4—6 inches high. Root leaves, slender-petioled, 3-parted, the divisions cut into linear, oblong obtuse lobes; leaves of the involucre similar on short petioles, their lobes slightly broader. Flowers usually solitary, half an inch or more broad on long peduncles; sepals 5, ovate or oval, obtuse, white, finely appressed-hairy and blue outside. Throughout the region in alpine meadows and slopes near the snow, flowering in June and July as the snows disappear. [Sidenote: =Anemone globosa= Nutt. _Wind-flower._] Stems 3—15 inches high, close, silky-hairy. Root leaves long-petioled, nearly semicircular in outline, 3-parted, the sessile divisions deeply lobed, with cleft, linear segments, involucral leaves similar, short petioled. Sepals 5—8, red, bluish or nearly pure white, half an inch or less long, soft, hairy outside, receptacle oblong, in fruit densely woolly. The most abundant anemone through the Rockies in the low open valleys, and, occasionally on the slopes, presenting the greatest variety of colouring from deep rosy pink to pure white and occasionally blue; flowering in early June. [Sidenote: =Pulsatilla hirsutissima= (Pursh.) Britton. _Pasque-Flower._] Villous, 6—18 inches high. Leaves much divided into narrow, linear, acute lobes, the basal on slender petioles, those of the involucre sessile and erect or ascending. Flowers bluish-purple, sometimes nearly white inside; sepals 5—7 ovate-oblong 1—1½ inches long, forming a cup; fruit a head of long silky achenes 2 inches or more in diameter. This is one of the earliest and most beautiful of all the spring flowers, in the open meadows and mountain sides, blossoming through May and June according to the situation. Probably its most common local name, in the Rockies where it is very abundant, is that of crocus, to which flower it does bear a superficial resemblance, in size, shape, and colour, and in the habit of the flower appearing as soon as the snow has left the ground, and before the leaves.

Freyn. _Western Anemone._] Stem rather stout, silky-hairy, 6—18 inches high, simple. Leaves biternate, the lower on long petioles, the divisions deeply pinnatifid into deeply cut linear, acute lobes; those of the involucre similar but short-petioled. Flowers 1½—2 inches broad, peduncled, the peduncles much elongated in fruit; sepals spreading, 6—7, oval-obtuse, white, the outside usually blue at the base; fruit of long plumose tailed achenes in a globular fluffy head. Frequent throughout the Rockies at an elevation of 6000 to 10,000 feet, blossoming on the edges of the snow banks as they recede, a conspicuous feature of many an alpine meadow during early June.
