Psammagrostis is a genus of plants in the grass family. [1] [2] [3] [4] The only known species is Psammagrostis wiseana, native to Western Australia. [5] [6]
Sorghum or broomcorn is a genus of about 25 species of flowering plants in the grass family (Poaceae). Sorghum bicolor is grown as a cereal for human consumption and as animal fodder.
A savanna or savannah is a mixed woodland-grassland biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. Four savanna forms exist; savanna woodland where trees and shrubs form a light canopy, tree savanna with scattered trees and shrubs, shrub savanna with distributed shrubs, and grass savanna where trees and shrubs are mostly nonexistent.
A lawn is an area of soil-covered land planted with grasses and other durable plants such as clover which are maintained at a short height with a lawn mower and used for aesthetic and recreational purposes—it is also commonly referred to as part of a garden. Lawns are usually composed only of grass species, subject to weed and pest control, maintained in a green color, and are regularly mowed to ensure an acceptable length. Lawns are used around houses, apartments, commercial buildings and offices. Many city parks also have large lawn areas. In recreational contexts, the specialised names turf, parade, pitch, field or green may be used, depending on the sport and the continent.
The Restionaceae, also called restiads and restios, are a family of flowering plants native to the Southern Hemisphere; they vary from a few centimeters to 3 meters in height. Following the APG IV (2016): the family now includes the former families Anarthriaceae, Centrolepidaceae and Lyginiaceae, and as such includes 51 genera with 572 known species. Based on evidence from fossil pollen, the Restionaceae likely originated more than 65 million years ago during the Late Cretaceous period, when the southern continents were still part of Gondwana.
Xanthorrhoea is a genus of about 30 species of succulent flowering plants in the family Asphodelaceae. They are endemic to Australia. Common names for the plants include grasstree, grass gum-tree, kangaroo tail, balga, yakka, yamina (Tasmania), and black boy. The most common species is Xanthorrhoea australis, and some of these names are applied specifically to this species.
The Xyridaceae are a family of flowering plants. This family has been recognized by many taxonomists and is known as the yellow-eyed grass family.
Pennisetum is a widespread genus of plants in the grass family, native to tropical and warm temperate regions of the world. They are known commonly as fountaingrasses. Pennisetum is considered a synonym of Cenchrus in Kew's Plants of the World Online.
Panicum (panicgrass) is a large genus of about 450 species of Poaceae grasses native throughout the tropical regions of the world, with a few species extending into the northern temperate zone. They are often large, annual or perennial grasses, growing to 1–3 m (3–10 ft) tall.
Triodia is a large genus of hummock grass endemic to Australia. The species of this genus are known by the common name spinifex, although they are not a part of the coastal genus Spinifex. Many soft-leaved Triodia species were formerly included in the genus Plectrachne. Triodia is known as tjanpi (grass) in central Australia, and have several traditional uses amongst the Aboriginal Australian peoples of the region.
Zygochloa is a genus of desert plants in the grass family known only from Australia. The only known species is Zygochloa paradoxa, commonly known as sandhill canegrass. It occurs in extremely arid areas such as the Simpson Desert.
Astrebla is a small genus of xerophytic 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.
Johnson grass or Johnsongrass, Sorghum halepense, is a plant in the grass family, Poaceae, native to Asia and northern Africa. The plant has been introduced to all continents except Antarctica, and most larger islands and archipelagos. It reproduces by rhizomes and seeds.
Austrostipa is a primarily Australian genus of plants in the grass family, commonly called speargrass.
The flora of Australia comprises a vast assemblage of plant species estimated to over 21,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (Banksia), Myrtaceae, and Fabaceae.
Parapholis incurva is a species of grass native to Europe, Asia and northern Africa, and widely naturalised elsewhere. Common names include coast barbgrass, curved sea hard grass, curved hard-grass, sicklegrass, curved sicklegrass and curved parapholis.
Thaumastochloa is a genus of Australian, Papuasian, and Indonesian plants in the grass family.
Parapholis is a genus of Eurasian and North African flowering plants in the grass family.
Whiteochloa is a genus of plants in the grass family.
Holcolemma is a genus of African, Asian, and Australian plants in the grass family.
Charles Edward Hubbard was a British botanist, specialising in agrostology – the study of grasses. He was considered "the world authority on the classification and recognition of grasses" in his time.
