First to bloom in the vicinity of New York (from March to May) is the HISPID BUTTERCUP (R. hispidus), densely hairy when young. The leaves, which are pinnately divided into from three to five leaflets, cleft or lobed, chiefly arise on long petioles from a cluster of thickened fibrous roots. The flower may be only half an inch or an inch and a half across. It is found in dry woods and thickets throughout the eastern half of the United States; whereas the much smaller flowered BRISTLY BUTTERCUP (R. Pennsylvanicus) shows a preference for low-lying meadows and wet, open ground through a wider, more westerly range. Its stout, hollow, leafy stem, beset with stiff hairs, discourages the tongues of grazing animals. June-August. Commonest of the early buttercups is the TUFTED BUTTERCUP (R. fascicularis), a little plant seldom a foot high, found in the woods and on rocky hillsides from Texas and Manitoba, east to the Atlantic, flowering in April or May. The long-stalked leaves are divided into from three to five parts; the bright yellow flowers, with rather narrow, distant petals, measure about an inch across. They open sparingly, usually only one or two at a time on each plant, to favor pollination from another one. Scattered patches of the SWAMP or MARSH BUTTERCUP (P. septentrionalis) brighten low, rich meadows also with their-large satiny yellow flowers, whose place in the botany even the untrained eye knows at sight. The smooth, spreading plant sometimes takes root at the joints of its branches and sends forth runners, but the stems mostly ascend. The large lower mottled leaves are raised well out of the wet, or above the grass, on long petioles. They have three divisions, each lobed and cleft. From Georgia and Kentucky far northward this buttercup blooms from April to July, opening only a few flowers at a time-a method which may make it less showy, but more certain to secure cross-pollination between distinct plants.
