PORTULACACEAE (PURSLANE FAMILY) 153 the corn root louse; also it is sometimes attacked by a white mold, which may make it a menace to better plants. Stems four inches to more than a foot in length, prostrate, thick, round, smooth, succulent, branching on all sides from the central root and again often forking. Leaves, alternate, obovate or wedge- shaped, with rounded tips, very small, thick, and fleshy, mostly clustered at the ends of the branches. Both stems and leaves often have a reddish tinge. Flowers solitary, sessile,, about a quarter-inch broad, opening only in the brightest sunshine; sepals two, broad, pointed, keeled; four to six — mostly five — broadly rounded yellow petals, soon falling away; stamens seven to twelve; style five- or six-parted. Capsule urn-shaped, one-celled, membranous, many-seeded, open- ing transversely and the top fall- ing off like a lid; when near maturity, the plants can hardly be touched without sowing these seeds by hundreds. The weed is most tenacious of life, often readjusting itself after having been torn up bodily, the fleshy stems, and leaves sustaining it while doing so, if not placed where the feat is impossible.

If old enough for seed- cones to begin, to form, plants should be removed from the soil, for the stems and roots retain life enough to ripen and distribute seed.
