Glaux maritima L. Morphological characteristics
Perennial herb with single or branched taproot. Stem erect or ascending, usually single or lower branched, 3-25cm high, hairless. The leaves are dense, small, fleshy, alternately opposite, nearly alternate, nearly sessile, lanceolate, oblong-lanceolate to ovate-lanceolate, 3-15mm long, 1.8-3.5mm wide, with a slightly pointed apex. , base cuneate, entire, glabrous. Flowers are small, axillary, with short pedicel, calyx broadly bell-shaped, 5-lobed, corolla, pinkish white to light red; stamens 5, ovary ovoid. Capsule nearly spherical (Fig. 120).

Geographic distribution
Widely distributed in Northeast China, Inner Mongolia, Hebei, Shandong, Shaanxi, Gansu, Tibet and areas south of the Yangtze River; abroad, it is also found in Mongolia, Central Asia, Siberia, the Far East, Europe and North America.
Biology and Ecological Characteristics
Sea milkweed is distributed in a wide area with widely varying ecological conditions, and its growth period also varies greatly. Generally, they turn green from the end of March to mid-May, buds form from May to early June, bloom from June to July, bear fruit from July to August, and turn yellow after frost. The reproductive period is about 90-150 days.
Sea milkweed is a medium-humid halophyte that likes to grow in salted meadows and swamp meadows on the seaside, lakeshores, riverside flats and terraces. Resistant to moisture and salt. The salt content in the 0-3cm soil layer can reach 32, and the lower layer can also grow in soil with a salt content of 2.5.
Feeding value
The stems are thin, soft and juicy. Sheep, rabbits, pigs and poultry like to eat it; horses, cattle and camels also eat it. In alpine meadows, swamp meadow short grass is one of the main pastures for livestock. From the perspective of chemical composition, the nitrogen-free leachate is rich, the ash content is high, the energy content is medium, and sea milkweed is a medium forage plant.
