. An illustrated flora of the northern United States, Canada and the British possessions : from Newfoundland to the parallel of the southern boundary of Virginia and from the Atlantic Ocean westward to the 102nd meridian. Botany. RANUNCULACEAE. Vol. II. 7. Anemone Richardsonii Hook. Richardson's Ane- mone. Fig. 1886. Anemone Richardsonii Hook. Fl. Bor. Am. i : 6. 1829. Low, slender, pubescent, 2-12' high from slender root- stocks. Basal leaves reniform, slender-petioled, 3-5-parted, the lobes acute, broadly oblong, dentate or crenate; those of the involucre similar, sessile; flower solitary, 9" broad, yellow; sepals about 6, oblong; head of fruit depressed- spherical; achenes nearly glabrous, compressed, ovate-oblong, reflexed, tipped with a hooked persistent style of about their own length. Labrador to Hudson Bay and in arctic America generally. Also widely distributed in Siberia. Summer. 8. Anemone quinquefolia L. Wind-flower. Snow- drops. Fig. 1887. Anemone quinquefolia L. Sp. PI. 541. i/53. Anemone nemorosa var. quinquefolia A. Gray, Man. Ed. 5, 38. 1S67. Low, simple, nearly glabrous, 4'-g' high, from horizontal rootstocks. Basal leaves long-petioled, appearing later than the flowering stem, 5-parted, the divisions oblong, cuneate, dentate; those of the involucre on slender petioles about 9" long, 3-5- parted, the divisions iV long, acute, variously cut and lobed; flower solitary, i' broad; sepals 4-9, obovate or oval, white, or purplish without; head of fruit globose, inclined; achenes pubescent, ob- long, tipped with the hooked styles. In low woods, Nova Scotia to Georgia, western On- tario, Minnesota and Tennessee. Ascends to 3500 ft. in Virginia. Readily distinguishable from the European A. nemorosa L., which is sometimes cultivated in our area and reported as escaped in Massachusetts, by its slender habit, slender petioles, less lobed divisions of the involucral leaves, paler green foliage^, more slender root stocks, and smaller flowers.
