Flowers are in flat clusters (umbels) about 2 inches across arising from leaf axils and at the end of branching stems. Each cluster has about 15 groups (umbellets) of 1/8 inch flowers. Individual flowers have 5 notched white petals, a greenish center, and 5 stamens.
Leaves and stem:
Leaves are compound with 3 or more linear blade-like leaflets. Leaflets are up to 3 inches long, less than 1/8 inch wide, and have irregular, widely spaced teeth, or may be toothless. Stems are branched, hollow and hairless.
This plant is deadly poisonous. The flat clusters of small white flowers is typical of members in the carrot family, but the leaves with fine, very narrow segments, and the spindly look of this plant distinguish it from related species such as Water Hemlock. The bulblets in the leaf axils are a distinguishing characteristic.
