Urochloa mutica, commonly known as para grass, buffalo grass, Mauritius signal grass, pasto pare, malojilla, gramalote, parana, Carib grass, and Scotch grass, is a species of grass. [2] [3] Despite its common name of California grass, [2] it does not occur in California; [4] it is native to northern and central Africa and parts of the Middle East, where it is cultivated for fodder. [3] It was introduced elsewhere and it is now cultivated throughout tropical regions of the world for this purpose. [2]
Para grass is a vigorous, semi-prostrate perennial grass with creeping stolons which can grow up to 5 metres (16 ft) long. The stems have hairy nodes and leaf sheaths and the leaf blades are up to 2 centimetres (0.8 in) wide and 30 centimetres (12 in) long. It roots at the nodes and detached pieces of the plant will easily take root in moist ground. The flower-head is a loose panicle up to 30 centimetres (12 in) long with spreading branches. The paired spikelets are arranged in uneven rows and are elliptical and 2.5 to 5 millimetres (0.1 to 0.2 in) long. The rachis is tinged with purple. Although many flower-heads grow, only a few viable seeds are produced, and propagation is usually by vegetative means. [1] [3] [5] [6] Para grass can be distinguished from the closely related tanner grass ( Brachiaria arrecta ) by its paired spikelets, tanner grass having single spikelets. [7]
Para grass is native to northern and central Africa and parts of the Middle East. [1] It was introduced into Central America but has largely been superseded there by other species of Brachiaria . It was also introduced into the humid, tropical parts of Australia around 1880 and has become widely naturalised in Queensland. By a few decades later it had become naturalised in much of southern Asia and on many Pacific islands, but is confined to its preferred habitat of poorly drained, swampy land. Along with tanner grass, it is planted as a fodder grass in seasonally flooded or swampy habitats, and in ponds in pastures, but it can block irrigation ditches and drains. [7] When used as forage for cattle it is usually controlled by the action of the animals, so it does not become too weedy. When it grows in other habitats, however, it can become noxious. It is aggressive and can form dense stands. It may also have allelopathic effects on other plants, preventing their growth. [8]
This species may have been introduced to the Americas on slave ships, on which it was used for bedding. It was in South America by the early 1800s and Mexico by 1872. It was introduced to Florida by the late 1870s to be used as fodder. It has since escaped cultivation in many areas and it now grows as a widespread weed. It is sensitive to frost so it generally does not persist outside warm regions. [2]
Para grass is mainly cultivated to feed livestock as it makes a high quality forage for ruminant animals. [9]
The plant is an invasive species in many Pacific Islands and Pacific Rim countries. [10]
The species has invaded the northern and north-western areas of Australia has the potential to spread further inland. [11] It is present in Kakadu National Park. In Australia, this grass forms vast stands, destroying waterfowl nesting habitat and displacing native plants. [12] [13]
In Florida this grass grows in various wetland habitat types, such as marshes and floodplains, as well as disturbed areas such as roadsides. In Hawaii this grass is widespread, especially in freshwater wetlands and in red mangrove (Rhizophora mangle) stands. It is thought to be a cause of the decline of the rare Hawaiian endemic Boyd's maiden fern (Thelypteris boydiae). [2]
Echinochloa crus-galli is a type of wild grass originating from tropical Asia that was formerly classified as a type of panicum grass. It is commonly known as cockspur, barnyard millet, Japanese millet, water grass, common barnyard grass, or simply "barnyard grass". This plant can grow to 1.5 m in height and has long, flat leaves which are often purplish at the base. Most stems are upright, but some will spread out over the ground. Stems are flattened at the base. The seed heads are a distinctive feature, often purplish, with large millet-like seeds in crowded spikelets.
The tropical grass species Cenchrus clandestinus is known by several common names, most often Kikuyu grass. It is native to the highland regions of East Africa that is home to the Kikuyu people. Because of its rapid growth and aggressive nature, it is categorised as a noxious weed in some regions. However, it is also a popular garden lawn species in Australia, New Zealand, South Africa and the southern region of California in the United States, being inexpensive and moderately drought-tolerant. In addition, it is useful as pasture for livestock grazing and serves as a food source for many avian species, including the long-tailed widowbird. The flowering culms are very short and "hidden" amongst the leaves, giving this species its specific epithet (clandestinus).
Macroptilium atropurpureum, commonly referred to as purple bush-bean, or siratro is a perennial legume recognized by its climbing, dense, green vines and deep purple flowers. The plant is indigenous to the tropical and subtropical regions of North, Central, and South America, as far north as Texas in the USA and as far south as Peru and Brazil. It has been introduced for use as a food for stock to many tropical regions around the world. It has become an invasive pest plant in a number of areas, including the north-eastern coast of Australia. Rich in protein, M. atropurpureum is commonly used for cattle pastures intercropped with grass, used in hay, or as a ground cover to prevent soil erosion and to improve soil quality.
Chloris gayana is a species of grass known by the common name Rhodes grass. It is native to Africa but it can be found throughout the tropical and subtropical world as a naturalized species.
Urochloa, commonly known as signalgrass, is a genus of plants in the grass family, native to tropical and subtropical regions of Eurasia, Africa, Australia, the Americas, and various islands.
Setaria sphacelata is a tall African grass, also known as South African pigeon grass and African bristlegrass. It is native to tropical and subtropical Africa, and is extensively cultivated globally as a pasture grass and for cut fodder. This is a rhizomatous perennial grass producing flattened, hairless, blue-green stems up to 2 m tall. The inflorescence is a dense, narrow panicle of bristly, orange-tinged spikelets up to 25 cm long.
Eragrostis curvula is a species of grass known by the common name weeping lovegrass. Other common names include Boer lovegrass, curved lovegrass, Catalina lovegrass, and African lovegrass.
Panicum repens is a species of grass known by many common names, including torpedo grass, creeping panic, panic rampant, couch panicum, wainaku grass, quack grass, dog-tooth grass, and bullet grass. Its exact native range is obscure. Sources suggest that the grass is native to "Africa and/or Asia", "Europe or Australia", "Eurasia", "Australia", "Europe, Asia, and Africa", or other specific regions, including the Mediterranean, Israel, and Argentina. It is present in many places as an introduced species and often a noxious weed. It has been called "one of the world's worst weeds."
Themeda quadrivalvis is a species of grass known by the common names grader grass, habana grass, and kangaroo grass, not to be confused with Themeda triandra, which is also known as kangaroo grass. It is native to India, Nepal, and Malaysia. It can also be found in many other places as an introduced species and often a noxious weed. It occurs in the United States, New Caledonia, Fiji, Mauritius, Thailand, Indonesia, Papua New Guinea, China, the Middle East and tropical America. It is a troublesome exotic weed in Australia, especially in northern regions. It is also an agricultural weed in crops such as sugar cane and lucerne.

Urochloa eminii, commonly known as Congo grass, is a species of forage crop in the family Poaceae that is grown throughout the humid tropics. With fast growth at the beginning of the wet season due to strong seedling vigour, ease of establishment, good seed production and yield and the ability to suppress weeds it has the ability to become developed into the most important forage crop planted in the tropics. With the aid of genomic tools to research the genotype and gain more information there is the ability to increase breeding programs which are currently rather limited.
