Family, Spurge. The flowers of this plant (for description of Family, see p. 9) are collected in umbellike groups of, usually, threes, surrounded by involucres of conspicuous, white-margined leaves. Stem, somewhat hairy, stout, tall, reaching 3 feet in height. Leaves, below the involucre, broad, ovate, smooth, with smooth margins. Umbels often forked.

This species is showy, not because of the flowers, but the white-bordered leaves. Often cultivated, but found wild in dry soil, waste places, westward and southward. (See illustration, p. 91.)
