Appearance
Halogeton glomeratus is a 2-17.7 in. (5-45 cm) tall, annual herb. The stems are often curved at the base and tinged reddish or purple.

Foliage
Leaves are alternate, sessile, semi-succulent, and 0.2-0.9 in. (4-22 mm) long.

Flowers
Flowers appear from June to September. Two flower types are present; larger flowers that are 0.08-0.12 in. (2-3 mm) wide with 5 light yellow or greenish-yellow sepals, and smaller flowers with tooth-like sepals. Neither of these flower types has petals, but they both have 2-5 stamens and 2 stigmas.

Fruit
Halogeton glomeratus produces two types of seeds. Seed produced in the early summer are light tan and wingless; seeds produced in the late summer are dark brown and winged.

Ecological Threat
Tissues of this plant accumulate salts from the soil. After a plant dies, these salts leach from the plant material and are deposited onto the topsoil, this favors Halogeton glomeratus seed germination and establishment. This plant is native to Eurasia and was introduced into the United States in the early 1930s. Preferred habitat includes roadsides, dry lakebeds, shrublands, and other arid and semi-arid regions.
