Beggar’s Lice (Hackelia virginiana)

The name seems to suppose that a beggar cannot afford real lice, which is a strange little piece of folk wisdom. This is one of those hitchhiker plants that spread themselves by sticking to your clothes, or to animals’ fur. This particular patch was growing among taller flowers on a sunny bank in Mount Lebanon, where it was blooming in late July.

Flowers.—The flowers grow on indefinitely long stems, one flower blooming at a time, with a cluster of buds dangling beneath the open flower, and developing seedpods in a line down the stem. As they develop, the “nutlets” grow grasping hairs. Each flower has five small white petals, regular, almost round.

Stems.—Covered with soft hair; up to about 4 and a half feet tall (about 1.5 m); many branches, held almost horizontally, with the seedpods dangling like bells along the underside.

Leaves.—Covered with soft hair, alternate, sessile or nearly so, shaped like an ellipse with tapered points at both ends.
