The plant is 4 ft. high. It flowers in August. Sea Rush is perennial and propagated by seed.
The stigma matures before the anthers, and self-pollination is thus rendered impossible. As in the other species of the genus the flowers are pollinated by the agency of the wind. There are 6 stamens, a short style, 3 stigmas, with wart-like knobs all over. The flowers last for a day and a half, the female condition only a day. The flowering is intermittent.
The capsule splits when ripe, and the seeds are numerous and dispersed close to the parent plant, this species growing in clumps covering wide areas.
The plant is a salt-lover, and grows in saline soil, being at the same time a sand plant, and addicted to sand soil.
Sea Rush is liable to attack by a fungus, Sclerotinia curreyana. Rushes, maritime and inland, are the resort of numerous Coleoptera, e.g. Agonium micans, A. puellus, Demetrius unipunctulatus, Quedius semiceneus, Crepidodera transversa. Cercus rufilabris, Telephorus ovalis; Heteroptera, Teratocoris Saundersi, Mecomma ambulans, Cyrtorrhinus caricis, C. pygmaeus; Homoptera, Liburnia venosa, L. limbata, L. douglasi, Livia juncorum.
Juncus, Pliny, is the Latin for rush. The second Latin name here refers to the maritime habitat.
The roots strike deep into the sand, and a clump forms a regular network or matted mass, and is excellent for reclaiming shifting sands. Hence it has been planted for coast protection with J. acutus, etc. The stems are cut clown when ripe, and dried like corn, and used for bedding, fodder, etc.
Essential Specific Characters: 305. Juncus maritimus, Lam. - Stem tall, erect, leaves terete, acute, long, flowers in long lax raceme, perianth-segments as long as capsule.
