Flowering branches 1—2 feet high, with long rough hairs, glandular above. Leaves reniform or cordate, sparingly rough-hairy, round lobed, and toothed with broadly ovate teeth; 1½—4 inches broad on hairy petioles 4—8 inches long; stem leaves short-petioled with well developed stipules. Flowers numerous in an elongated raceme; sepals ovate ¼ of an inch long; petals white, purplish or pink with a pinnately cut blade; claws broadly wedge-shaped, ⅛ of an inch long, erect, blade spreading or reflexed with a rounded ovate body and tapering thread-like lobes. Moist woods and crevices in the rocks, abundant in the Selkirks; flowering in June. [Sidenote: =Mitella nuda= L. _Naked Bishop’s-Cap._] Perennial, from a slender branched rootstock, producing long runners in late summer; flowering branches scape-like, naked, or rarely with a small leaf, 2—8 inches high, sparingly hairy. Leaves reniform ¾—2 inches in diameter, rounded, crenate or lobed, on petioles 1—3 inches long. Flowers few, in a loose raceme, saucer-shaped; calyx about ¼ of an inch broad, greenish-yellow; petals spreading about twice as long as the sepals, greenish-yellow, pinnately divided into thread-like divisions, resembling snow crystals in form. Common in the cool woods and shaded mossy bogs throughout the Rockies; flowering in June. [Illustration: Mitella nuda L. (⅔ Nat.) Naked Bishop’s-Cap.] [Illustration: Pectiantia pentandra (Hook.) Rydb. (¼ Nat.) Mitrewort.] [Sidenote: =Pectiantia pentandra= (Hook.) Rydb. _Mitrewort._] Flowering branches scape-like, 4—12 inches high, naked. Leaves broadly crenate with 9—11 more or less distinct round lobes, thin, 1—2½ inches broad on petioles, 2—4 inches long. Flowers ⅛ of an inch broad in a slender loose raceme, green or often purplish inside; sepals broadly triangular-ovate, obtuse, and recurved; petals yellowish, deeply cut into slender thread-like divisions, twice as long as the calyx; stamens 5, opposite the petals. Throughout the region in cool woods and shaded springy spots; flowering in early June at the higher altitudes. [Sidenote: =Pectiantia Breweri= (A. Gray.) Rydb. _Mitrewort._] Flowering branches 4—8 inches high, leafless. Leaves thin, broadly reniform with many shallow rounded lobes; petioles 2—4 inches long. Flowers in a loose raceme, green, occasionally in pairs; calyx ⅛ of an inch wide; sepals obtuse and reflexed; petals deeply cut into thread-like divisions about twice as long as the sepals; stamens 5, opposite the sepals. In damp woods throughout the region, growing with the previous species; flowering in early June. [Sidenote: =Heuchera glabra= Willd. _Smooth Alum-root._]
