The leaf is rolled into a vertical tube and part of the folded inner surface is shown here. Like other xerophytes, marram grass is well adapted to its surroundings in order to thrive in an otherwise harsh environment.

Marram grass grows on coastal sand dunes all over the world. Posted by. Fig. All products are produced on-demand and shipped worldwide within 2 - 3 business days. The grass is invasive in the local ecosystems, forming dense monotypic stands that crowd out native vegetation, reduce species diversity of native arthropods, and cover vital open stretches of sand used for nesting by the threatened western snowy plover (Charadrius nivosus).

Not only is it invasive in California, it is also a highly invasive weed in coastal areas of New Zealand and Western Australia, where it was introduced for the same purpose in California, to stabilise dunes; outcompeting native spinifex species. 4. The inner surface of the leaf has hinge cells which when deflated (during dry conditions) cause the leaf to … In the Northern Hemisphere, it grows between 30 and 63 degrees north latitude. Its seed-heads are relatively large (7-30 cm long) and its flower spikelets only have a single tiny flower (i.e. One clump can produce 100 new shoots annually. The air part consists of tufts of leaves in the rosette form (figure 1). The external face of the leaves is smooth, whereas the internal part contains parallel veins characteristic of the monocot plant [24] (figure 1). This sand-adapted grass was introduced to the beaches of western North America during the mid-19th century to provide stabilization to shifting sand dunes. J. Ecology. The fungi, always found in soil, may decrease the vigour on the stabilized sand. Beach with sand dunes and grass marram in the soft evening sunset light. 2) Its leaves are coated with a waxy cuticle which mimizes water loss. Coarse perennial grass with glaucous-grey tufts to 170cm, fibrous roots. Marram grass and cacti both have this adaptation as marram grass has micro hairs in the stomata pits and cacti normally have spines which are … Marram grass survives in the arid environment of a sand dune by rolling up its leaves during long periods of drought, so that all the leaves’ breathing pores or stomata are inside the rolled leaf, minimising water loss. Marram grass. Fig. [2] The leaves are up to 1 metre (3.3 ft) long and sharply pointed. [2], Ammophila arenaria is a perennial plant, which means it can live for many years. [3] In winter, because of the cold temperatures, growth is very slow but does not stop. It mainly grows in spring when leaf production exceeds leaf senescence. Ammophila australis is a synonym of Ammophila arenaria subspecies australis (Mabille) M.Laínz, Ammophila arenaria is a species of flowering plant in the grass family Poaceae. This fly also belongs to the Muscidae or houseflies. Flower-heads are dense, cylindrical spike-like contracted panicles, 8-25 cm long and 1-3 cm wide. Marram grows on sand dunes (see previous photo 'Marram growing on sand dunes'), where water quickly drains through the sand and is not retained as in a ‘normal’ soil. 5 characteristics are that marram grass holds the sand for the dune to stay together. Russo, M., Pickart, A., Morse, L., & Young, R. (1988). This salt-loving halophyte has a vital role in sand dune ecology. 8 years ago. Changes in structure and function of Ammophila during primary succession. [4] But this is changed to May in Europe because of the different climates. Coarse perennial grass forming stiff, hardy, dull grey clumps of erect stems (<1.2 m) growing from a network of thick rhizomes which can grow laterally up to 2 m in six months. and Colletotrichum graminicola) are present on the island. This reduces the leaf area exposed to the air and so reduces the transpiration rate. https://www.alamy.com/stock-photo-sand-dune-with-marram-grass-against-a-beautiful-blue-sky-73836726.html, Marram grass on a finely corrugated Beach, https://www.alamy.com/marram-grass-on-a-finely-corrugated-beach-image217197828.html, https://www.alamy.com/stock-photo-sand-dunes-and-marram-grass-brackley-prince-edward-island-national-43925667.html, https://www.alamy.com/marram-grass-leaf-cross-section-100x-image274309819.html, Helina reversio on pausing on a Marram Leaf. 6 3 3 336.

In the Myrtle-Type the leaves are thick, leathery, and evergreen, sometimes large, as in the Rhododendron, sometimes small, as in the box.. Marram grass grows on sand dunes. Another characteristic is that the grasses roots are very long and strong. Though the adult plant is strong, the seeds have low viability, and the seedlings also have low survival rates as well because of desiccation, burial, and erosion. 12), characteristic of many heath-plants-e.gr., Erica, Empetrum, Calluna. The cylindrical inflorescence is up to 30 centimetres (12 in) long.
