Brief Summary

provided by Ecomare
Marsh arrowgrass can grow in saline conditions, but doesn't tolerate salt as much as its family member sea arrowgrass. It grows vertically out of the ground, its flowers are spread further apart along the stem and it doesn't form the clusters that sea arrowgrass makes. It can be found along the banks of ditches, along (brackish) ditches and in damp hay-fields and sometimes even in tremulous peat grounds. It is found in the dunes in wet valleys. On beach plains surrounded by dunes, marsh arrow-grass is especially found in the border regions between salt and fresh water.

Description

provided by eFloras
Erect perennial with (10-) 20-50 cm. long scapes, usually in fresh water marshes or water channels, glabrous, somewhat fleshy; plant base looking somewhat bulb-like with dense fibrous roots, but rhizome long, slender. Leaves linear, semi-terete, usually deeply furrowed on upper surface towards the base, usually about half as long as the scapes, 2-3 mm. wide, sheathing at the base; sheath 5-8 cm. long, slightly broader than the blade. Scapes elongating in fruit; racemes 30-80-flowered, terminal, much elongated after flowering, usually 20-30 cm. long in fruit. Flowers c. 3 mm. across. Perianth segments 1.5-2 (—2.5) mm. long, 1-1.5 (—2) mm broad, elliptic-ovate, greenish or whitish with usually purplish margins, glabrous. Stamens about half the length of perianth segments, almost sessile; anthers purplish, 0.5 mm. long. Pedicel stiff, filiform, 3-5 mm long, ascend¬ing, somewhat appressed to the axis in fruit but shorter than it. Fruit linear¬clavate or oblong-linear, tapering towards the base, (6—) 8-10 mm. long, 1 mm broad, ± appressed to the axis, glabrous, separating into three mericarps (each with 1 fertile and 1 sterile carpel together) from below upwards when ripe leaving a triangular axis but mericarps remaining connate with stigma after dehiscence; each mericarp somewhat terete, subulate, tapering-aristate at the base, 1-seeded and 1-loculed; seed nearly as long as the carpel, brown, linear-ellipsoid.

Triglochin palustris

provided by wikipedia EN

Triglochin palustris or marsh arrowgrass[1][2] is a species of flowering plant in the arrowgrass family Juncaginaceae. It is found in damp grassland usually on calcareous soils, fens and meadows. The species epithet palustris is Latin for "of the marsh" and indicates its common habitat.[3] It has a circumboreal distribution, occurring throughout northern parts of the Northern Hemisphere. It can be found locally in the British Isles especially the north.[4]

Description

It is a slender perennial herb 15 to 40 cm tall. It has no stolons, and emits a pleasant aromatic smell when bruised.

The leaves are linear, 10 to 20 cm long, rounded on the lower side, deeply grooved on the other.

It has many 3 petaled flowers arranged in a long spike, with purple edged perianth segments, 2 mm long. It flowers from June until August.[5]

The fruits are club shaped, 10 mm long and 2 mm wide. These plants can adapt to animals attacking it by closing its self in.

Similar species

Triglochin maritimum (sea arrowgrass) is similar but has the following differences: it has stolons, is stouter. The leaves are fleshy and not furrowed above. It is not very aromatic. The raceme are more dense and like Sea Plantain. The flowers are fleshier. The fruits are oval, 4 mm long, 2 mm wide.
