littleleaf buttercup
Ranunculus abortivus L.
Littleleaf buttercup changes its appearance as the eye follows a stem upward. Near the ground, kidney-shaped leaves make a low rosette; above them, much narrower leaves accompany an airy, branching flower stalk. The small blossoms have green centers, so their yellow petals can be less conspicuous than the foliage. NC State Common Wetland Plants Guide: Ranunculus abortivus

Recognizing the plant
Flowering stems stand about 10–60 cm tall and are generally smooth. The basal blades have heart-shaped bases and scalloped edges, and remain present while the plant blooms. Each flower has five yellow petals only about 1.5–3.5 mm long, often shorter than the sepals behind them. After flowering, numerous smooth, flattened achenes form an oval head. Each tiny fruit ends in a very short, curved beak, a useful feature when distinguishing this species from other small-flowered buttercups.
