POTENTILLA MILLEFOLIA 11. sp.
Low, prostrate or spreading ; stems numerous from the caudex, about I dm. long, few-leaved, only a little exceeding the basal leaves, appressed-strigose, often sparingly so. Lower stipules lanceolate and scarious and brown, the upper ovate-lanceolate, acute or acuminate, green, often 2-3 cleft. Basal leaves pinnate, of many pairs, sparingly strigose-ciliatc, nearly as long as the stems; stem-leaves much reduced. Leaflets divided nearly to the base into linear subulate divisions, which therefore look as if verticillate. Pedicels slender, I-2 cm. long, in fruit abruptly reflexed below the strigose-hirsute calyx. Bractlets and sepals lanceolate, acute, the
former slightly smaller. Corolla 12-18 mm. in diameter. Petals obcordate, deeply notched, longer than the sepals. Stamens about 20. Achene smooth, with a slender filiform nearly terminal style. (Plate 277, figs. I-5.) P. millefolia most resembles P. Plattensi s, but differs in the long and very narrow segments of the leaves, the reflexed fruiting calyx and the longer sepals. The following specimens have been ex amined : G. Lemmon, 1873, 1874, and no. 86, 1875 (Type); E. L. Greene, no. 75o, 1876; J. W. Congdon, no. 277, 1880.
