Triglochin maritima is a species of flowering plant in the arrowgrass family Juncaginaceae. It is found in brackish marshes, freshwater marshes, wet sandy beaches, fens, damp grassland and bogs. It has a circumboreal distribution, occurring throughout the northern Northern Hemisphere. In the British Isles it is common on the coast, but very rare inland.

Description

It is similar to marsh arrowgrass (Triglochin palustris) but has the following differences: it has stolons, is stouter. [3] The leaves are fleshy and not furrowed above. It is not very aromatic. [3] The raceme is more dense and like sea plantain. The flowers are fleshier. [4] The fruits are oval, 4 mm long, 2 mm wide. [3]

It varies in height from 200–750 mm (8–30 in). It flowers in May to August; flowers are greenish, 3 petalled, edged with purple, 3 mm (18 in) across, in a long spike. [5] [6] Common names include seaside arrowgrass, [7] common arrowgrass, sea arrowgrass and shore arrowgrass.[ citation needed ]

It can be an annual or perennial. [8]

Triglochin concinna is a synonym of this species. [9]

This plant is believed to be toxic, as it can produce cyanide. However, this is usually when the plant is distressed in drought conditions or due to over harvesting, usually by grazing animals. There is a common belief that this species has been known to cause losses in cattle, with green leaves being more toxic than dried material, yet sheep and deer graze on the plant, especially in rural seaside areas. It could be that belief in the plants' toxicity is apocryphal and based on anecdotal evidence. [10] [4]

<i>Triglochin palustris</i> Species of flowering plant in the arrowgrass family


Triglochin palustris or marsh arrowgrass 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. 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.

Puccinellia howellii is a rare species of grass known by the common name Howell's alkaligrass. It is endemic to Shasta County, California, where it is known from a single population in Whiskeytown National Recreation Area near Whiskeytown. Its entire population is contained in a 1-acre (4,000 m2) complex of three saline mineral springs directly next to Highway 299. The grass was first described to science in 1990 and no other populations were discovered despite extensive searches of the area.

<span class="mw-page-title-main">Salt pannes and pools</span> Water retaining depressions located within salt and brackish marshes

Salt pannes and pools are water retaining depressions located within salt and brackish marshes. Pools tend to retain water during the summer months between high tides, whereas pannes generally do not. Salt pannes generally start when a mat of organic debris is deposited upon existing vegetation, killing it. This creates a slight depression in the surrounding vegetation which retains water for varying periods of time. Upon successive cycles of inundation and evaporation the panne develops an increased salinity greater than that of the larger body of water. This increased salinity dictates the type of flora and fauna able to grow within the panne. Salt pools are also secondary formations, though the exact mechanism(s) of formation are not well understood; some have predicted they will increase in size and abundance in the future due to rising sea levels.

<i>Spergularia media</i> Species of flowering plant in the pink family Caryophyllaceae

Spergularia media is a species of flowering plant in the family Caryophyllaceae known by the common names media sandspurry and greater sea-spurrey. It is native to Eurasia and the Mediterranean, where it grows in many types of habitat, including disturbed areas, including places with saline substrates, such as salt marshes and beaches. It is known in many other parts of the world as an introduced species and a common roadside weed. In North America it is a "highway halophyte", often springing up at the margins of roads that are heavily salted in the winter.

Bamburgh Coast and Hills is the name given to a Site of Special Scientific Interest (SSSI) on the coast of north Northumberland, England. The site is one of the longest-standing SSSIs in England, having been listed since 1954, and displays the interaction of a fluid magma rock, now known as the Whin Sill, interacting with older sedimentary rock. Coastal erosion at the site enables sections of the geological strata to be seen. In turn, the soil associated with the Whin Sill gives rise to a distinct pattern of vegetation which on its own merits is at this site found notable.
