Mitchell Grass
''Astrebla'' is a small genus of xerophytic (adapted to survive in an environment with little liquid water) grasses found only in Australia. They are the dominant grass across much of the continent. They are commonly known as Mitchell grass after Scottish explorer, Thomas Mitchell (1792-1855), who first collected a specimen near Bourke in New South Wales. Mitchell grasses grow on clay soils, mainly between an upper limit of and a lower limit of average annual rainfall, and at even lower rainfall in depressions where the water concentrates following rains, for example in Sturt's Stony Desert. Mitchell grasses are deep-rooted and become dormant during drought, allowing them to survive extended periods without rainfall. They are commonly found clumped together and reaching one metre high, providing habitat for organisms such as mammals. ; Species See also * List of Poaceae genera The true grasses ( Poaceae) are one of the largest plant families, with around 12,000 species ...

Astrebla Squarrosa
''Astrebla squarrosa'', commonly known as bull Mitchell grass, is a long lived herb of the family Poaceae. Named in honour of Thomas Mitchell, it is regarded as the most flood tolerant of the Astrebla ''Astrebla'' is a small genus of xerophytic (adapted to survive in an environment with little liquid water) grasses found only in Australia.

Often seen growing to 1.5 metres tall, on floodplains and heavy dark clay soils in arid to semi arid Australia. The coarse stems and difficult digestibility make this a less desirable Mitchell grass for livestock. Flowering is in response to rain.

Astrebla Pectinata
''Astrebla pectinata'', commonly known as barley Mitchell grass, is a herb of the family Poaceae from the order Poales. Morphology and habitat ''Astrebla pectinata'' grows to 1 m (3.25 ft). The flowers are pollinated by wind and are hermaphrodite In reproductive biology, a hermaphrodite () is an organism that has both kinds of reproductive organs and can produce both gametes associated with male and female sexes.

The species is considered to be the most balanced and economically important herbage in the semiarid areas of eastern Australia. It is a warm-season perennial grass. It is palatable to livestock even when it is dry. References Chloridoideae Flora of Australia Plants described in 1838 Taxa named by John Lindley {{Chloridoideae-stub ...

Poales Of Australia
The Poales are a large order of flowering plants in the monocotyledons, and includes families of plants such as the grasses, bromeliads, and sedges. Sixteen plant families are currently recognized by botanists to be part of Poales. Description The flowers are typically small, enclosed by bracts, and arranged in inflorescences (except in three species of the genus ''Mayaca'', which possess very reduced, one-flowered inflorescences). The flowers of many species are wind pollinated; the seeds usually contain starch. Taxonomy The APG III system (2009) accepts the order within a monocot clade called commelinids, and accepts the following 16 families: The earlier APG system (1998) adopted the same placement of the order, although it used the spelling "commelinoids". It did not include the Bromeliaceae and Mayaceae, but had the additional families Prioniaceae (now included in Thurniaceae), Sparganiaceae (now in Typhaceae), and Hydatellaceae (now transferred out of the monocots; r ...

Bunchgrasses Of Australasia
Tussock grasses or bunch grasses are a group of grass species in the family Poaceae. They usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies. As perennial plants, most species live more than one season. Tussock grasses are often found as forage in pastures and ornamental grasses in gardens. Many species have long roots that may reach or more into the soil, which can aid slope stabilization, erosion control, and soil porosity for precipitation absorption. Also, their roots can reach moisture more deeply than other grasses and annual plants during seasonal or climatic droughts. The plants provide habitat and food for insects (including Lepidoptera), birds, small animals and larger herbivores, and support beneficial soil mycorrhiza. The leaves supply material, such as for basket weaving, for indigenous peoples and contemporary artists. Tussock and bunch grasses occur in almost any habitat w ...
