Flowering stems slender, 4—20 inches high, smooth, 1—3-leaved. Basal leaves on petioles, 2—8 inches long, cordate, deeply 5—7-lobed, thin, shining, 1—4 inches broad and as long or slightly longer, lobes triangular-ovate, acute, doubly and sharply serrate. Flowers in a loose panicle 2—6 inches long; calyx with the turbinate base about ⅛ of an inch long, sparingly fringed with hairs; petals white, broadly spatulate, acute, about twice as long as the sepals; stamens much exserted, with scarlet and orange anthers. On damp shaded rocks, especially abundant in the Selkirks in the vicinity of Glacier. [Sidenote: =Heuchera ovalifolia= Nutt. _Round-leaved Alum-root._] Flowering branches naked, densely glandular-hairy, 1—2 feet high. Leaves round-oval, ½—1½ inches broad, ¾—2 inches long, rounded, slightly heart-shaped at the base, round-lobed and crenate with bristle-tipped teeth. Flowers in a short dense raceme less than 4 inches long, the deeply campanulate, yellowish, densely hairy base of the calyx, with the broadly oblong sepals ¼ of an inch long, petals usually wanting. On dry rocky banks and hillsides throughout the region, flowering in midsummer. [Sidenote: =Tiarella unifoliata= Hook. _Foam-Flower._] Flowering branches 6—15 inches high, 1—4-leaved. Leaves broadly cordate, coarsely 3—5-lobed with broadly ovate-acute lobes, doubly crenate with mucronate teeth; stem leaves short-petioled, basal, on petioles 2—6 inches long. Flowers in a narrow panicle; sepals whitish ovate-oblong, ¹/₁₆ of an inch long, the linear-subulate, white petals and stamens fully three times as long; carpels oblong acute, nearly half an inch long in fruit. Abundant in damp rich woods throughout the region oftentimes carpeting the ground; flowering in June. [Sidenote: =Hemieva ranunculifolia= (Hook.) Raf. _Hemieva._] Light yellowish-green; stems 8—10 inches high from a rosy-bulbous rootstock. Leaves ternately divided to the base, the middle division broadly wedge-shaped, ½—1 inch long, rounded, 3-lobed, the lateral ones oblique and 4-lobed; basal, on petioles 2—4 inches long, stem leaves on short petioles dilated at the base, the uppermost sessile, merely 3-lobed at the apex. Flowers showy in a short dense corymb; the base of the calyx and sepals yellowish-green about ⅛ of an inch long; petals white or yellowish, broadly spatulate, ¼ of an inch long; stamens 5, opposite the sepals, filaments and carpels more or less rosy in colour. On wet rocky slopes in the Selkirks at Glacier, not common; flowering in June. [Illustration: Saxifraga cernua L. (⅔ Nat.) Nodding Saxifrage.] [Illustration: Saxifraga rivularis L. (⅔ Nat.)
