Dryas (Greek, wood-nymph). Rosaceae. Dwarf hardy tufted evergreen somewhat shrubby plants, sometimes transferred to gardens. Leaves alternate, petioled, simple, entire or crenate, tomentose: fls. large, white or yellow, borne singly on slender scapes; sepals 8-10, persistent; petals 8-10, obovate or oval; stamens many, with subulate filaments; pistils many, sessile, with a terminal style that persists and elongates on the achene. High northern or mountain plants, of N. Amer., Eu. and Asia, of which 4 species are recognized by Rydberg (N. Amer. Flora, xxii, part 5, 1913); allied to Geum. The best known cult. species, D. octopetala, requires a well-drained porous soil, a sunny but not dry position. It is well to shade the foliage from bright sun during the winter months with evergreen branches to prevent the foliage from having a scorched appearance. A capital plant for the rockery. Propagated by cuttings, division, or by seed. (J. B. Keller.) D. integrifolia, Vahl. Fla. white; sepals linear or linear-lanceolate: lvs. lanceolate or lance-elliptic, the margins mostly revolute. High northern N. Amer.—D. tomentosa, Farr. Fls. yellow, sepals ovate or ovate-lanceolate: lvs. obovate or elliptic, coarsely crenate,tomentose on both surfaces. Canadian Rockies. L. H. B.
