*Tall Cinquefoil.* _Potentilla arguta._ Found among tall grasses in fields and meadows in June. The stout leafy stalk grows between 2 and 3 feet high; it branches for the flowers, and is stout, woody-fibred, and hairy to the touch. The color is a pale yellow-green, with red-brown hairs. The root, and lower, leaves are divided into 3 to 11 long, oval leaflets, and are set on long stems; the upper leaves are 3-divided, and set on short stems which clasp the stalk with a pair of wings; the margin is toothed, ribs and veins being prominent, and the surface is downy with hairs. Green in color. The flower has 5 petals, that are round with a pointed base, of a fine texture, and creamy-white color; the stamens are many, thread-like, and bright yellow; the yellow pistils are gathered prominently in the center. The calyx is 5-parted, and green; close beneath it occur 5 narrow, spreading bracts that are shorter than the calyx-parts, and green. The flowers, on short leafy stems, are placed in groups of two or three, forming loose terminal clusters. The long pointed bases, by which the petals are attached, permit the calyx to be seen, from above, as a green star at the bottom of the shallow creamy cup; the calyx is noticeably flat, and sticky.

The stalk is about 6 inches high, branching somewhat, slender, stiff, tough fibred, and covered closely with silky white wool, through which the pinkish color of the bark shows. The leaflets are 5, each being deeply cleft 5 to 9 times; the margin is entire, and the edge is slightly rolled under; the texture is very smooth and fine; the upper side of the leaf is dark green, the underside is covered with a white silky wool. The lower leaves are set on long stems, the upper leaf-stems gradually shorten till they disappear and the leaves themselves clasp the stalk with a pair of wings. The flower is like the Five-finger blossom, but smaller, with many stamens; in color it is a light clear yellow. The calyx-parts are as long as the petals; green above, and white underneath. The flowers, on short leafy stems, form little terminal groups. The silver lining of the pretty leaf outlined by its tiny rolling edge of bright green is a highly attractive feature, and the surface is charming to the touch.

This bushy, branching, and very leafy plant grows from 1 to 3 or 4 feet high; it is tough, and woody-fibred, with a thin bark, roughened by hairs. Dull tawny-brown in color, dark at the foot. The new shoots are covered with white down.
