Hooked Buttercup

Description:

1-2' tall, consisting of some basal leaves, branched stems with alternate leaves, and flowers. The basal leaves are up to 5' long and 5' across; they have long hairy petioles. Each basal leaf is palmately cleft into 3-5 lobes; these lobes are often divided again into smaller lobes. The alternate leaves are similar to the basal leaves, except they become smaller as they ascend the stems and their petioles are shorter. The upper leaves are more slender and divided into fewer lobes. The margins of the leaves are crenate or dentate. The upper surface of each leaf is medium to dark green and glabrous. The stems are light green, terete, and covered with long hairs; they are erect to ascending, rather than sprawling across the ground. The upper stems terminate in loose clusters of flowers. Each flower is about 1/3' across, consisting of 5-6 yellow petals, 5 light green sepals, a dense green cluster of pistils, and a ring of surrounding stamens with yellow anthers. The petals are oblong-elliptic and a little shorter than the sepals; the latter tend to hang downward while the flowers are blooming. The pedicels of the flowers are pubescent. The blooming period occurs from mid-spring to early summer and lasts about 1 month. Both sepals and petals are deciduous and they soon fall to the ground. The pistils become transformed into a dense cluster of flat-sided achenes with slender hooked beaks; this fruit is globoid in shape. Eventually, the fruit changes in color from green to nearly black. Each achene is about 2-3 mm. long. The root system consists of a cluster of fibrous roots and occasional rhizomes. Sometimes, small vegetative colonies of plants are produced.

Habitat:

Native to eastern North America from central Quebec south to Florida. Habitats include damp depressions in upland woodlands, floodplain woodlands, shaded areas along streams, bottoms of rocky ravines, areas along woodland paths, swamps, forested bogs, and shady seeps. This species prefers damp woodlands and shaded wetlands.
