Nassella Trichotoma
''Nassella trichotoma'', the serrated tussock, is a type of bunchgrass plant, native in Argentina, Uruguay, Chile, and Peru. It is on the list of Weeds of National Significance in Australia, reducing the productivity of pasture and creating a fire hazard. In many states, landowners are required by law to keep their land free of this plant. In New Zealand is classed as an unwanted organism by Biosecurity New Zealand and is under strict control regimes by some of the regional councils.

Eduard Hackel
Eduard Hackel (17 March 1850, Haida, Bohemia – 2 February 1926, Attersee, Upper Austria) was an Austrian botanist. His father was a veterinarian in Haida (now Nový Bor) in Bohemia. He was married and had one son. Hackel studied at the Polytechnical Institute in Vienna, and became substitute teacher at a high school in St. Pölten in 1869. He became full professor of natural history there upon obtaining his teaching certificate in 1871 and remained in this position until his retirement in 1900. Agrostology He published his first agrostology papers on grasses in 1871 and soon became known as a world expert agrostologist on the grass family (Poaceae). While he himself undertook only a single collecting trip – to Spain and Portugal, he was charged with working up collections of grasses mainly from Japan, Taiwan, New Guinea, Brazil and Argentina. Apart from agrostologisty systematics, Hackel also contributed to the morphology and histology of members of the grass family. T ...

Bunchgrass
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 ...

Uruguay
Uruguay (; ), officially the Oriental Republic of Uruguay ( es, República Oriental del Uruguay), is a country in South America. It shares borders with Argentina to its west and southwest and Brazil to its north and northeast; while bordering the Río de la Plata to the south and the Atlantic Ocean to the southeast. It is part of the Southern Cone region of South America. Uruguay covers an area of approximately and has a population of an estimated 3.4 million, of whom around 2 million live in the metropolitan area of its capital and largest city, Montevideo. The area that became Uruguay was first inhabited by groups of hunter–gatherers 13,000 years ago. The predominant tribe at the moment of the arrival of Europeans was the Charrúa people, when the Portuguese first established Colónia do Sacramento in 1680; Uruguay was colonized by Europeans late relative to neighboring countries. The Spanish founded Montevideo as a military stronghold in the early 18th century bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chile
Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the east and the Pacific Ocean to the west. Chile covers an area of , with a population of 17.5 million as of 2017. It shares land borders with Peru to the north, Bolivia to the north-east, Argentina to the east, and the Drake Passage in the far south. Chile also controls the Pacific islands of Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island in Oceania. It also claims about of Antarctica under the Chilean Antarctic Territory. The country's capital and largest city is Santiago, and its national language is Spanish. Spain conquered and colonized the region in the mid-16th century, replacing Inca rule, but failing to conquer the independent Mapuche who inhabited what is now south-central Chile.

Nassella
''Nassella'', or needlegrass, is a New World genus of over 100 perennial bunchgrasses found from North America through South America. The Latin word ''nassa'' refers to "a basket with a narrow neck". It is usually considered segregate from the genus ''Stipa'' and includes many New World species formerly classified in that genus. As of 2011, ''The Jepson Manual'' includes ''Nassella'' within ''Stipa''. ''Nasella'' is characterized by strongly overlapping lemma margins and reduced, veinless paleae. The lemma tips are fused into the "crown", a short membrane that surrounds the base of the lemma. The rim of the crown usually has hairs. Many species form both cross-pollinating and self-pollinating florets in the terminal panicle. The self-pollinating florets have 1–3 small anthers; the cross-pollinating florets have 3 longer anthers. Some species have self-pollinating inflorescences hidden in their basal leaf sheaths. These hidden inflorescences lack glumes and usually lack awn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grasses Of Argentina
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, primari ...
