Identification

Basal and lower stem leaves are palmately divided into 3 leaflets. The lateral leaflets are sometimes deeply cut making the leaf appear to have 5 leaflets — “3 looks like 3 (or 5)”.

The flowers are white. There are 4 to 11 flowers, usually 7 or fewer, in each flower cluster. All umbellets include both male flowers and usually 3 perfect flowers. Perfect flowers are stalkless. Male flowers are on long stalks, rising above the perfect flowers. The sepals are longer than the petals. There are 1 to 8 stamens. They do not protrude beyond the calyx lobes. The styles are inconspicuous, shorter than the calyx.

The seed capsules are ¼ to 5 16 long. The sepals in fruit converge, forming a beak as long or longer than the bristles. The styles in fruit are inconspicuous, shorter than the bristles.
