This grass grows a dense tussock with extended stolons, which are covered with hairs or without hairs. [6] Each grass, erect or ascending, reaches between 35 and 180 cm tall. [5] The lowest basal leaf sheaths are densely hairy, or very rarely smooth. [5] The leaf blades are typically 5–60 cm long, 2–14 mm wide and may be either hairy or ...
Tussock grasses are often found as forage in pastures and ornamental grasses in gardens. [ 1 ] [ 2 ] [ 3 ] Many species have long roots that may reach 2 meters (6.6 ft) or more into the soil, which can aid slope stabilization, erosion control , and soil porosity for precipitation absorption.
Poaceae, also known as the true grasses, is the fourth largest plant family in the world with around 12,000 species and roughly 800 genera. [ 1 ] [ 2 ] They contain, among others, the cereal crop species and other plants of economic importance, such as the bamboos , and several important weeds .
It includes the cereal grasses, bamboos, 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, [ 4 ] the Poaceae is the fifth-largest plant family , following the Asteraceae , Orchidaceae , Fabaceae and Rubiaceae .
The Pooideae are the largest subfamily of the grass family Poaceae, with about 4,000 species in 15 tribes and roughly 200 genera. They include some major cereals such as wheat, barley, oat, rye and many lawn and pasture grasses. They are often referred to as cool-season grasses, because they are distributed in temperate climates. [1]
The following species in the grass genus Paspalum are accepted by Plants of the World Online. [1] Species are somewhat difficult to delineate by traditional morphological methods. [ 2 ] [ 3 ]
It is a common and incredibly popular lawn grass in North America with the species being spread over all of the cool, humid parts of the United States. In its native range, Poa pratensis forms a valuable pasture plant, characteristic of well-drained, fertile soil.
The vegetation of tended pasture, forage, consists mainly of grasses, with an interspersion of legumes and other forbs (non-grass herbaceous plants). Pasture is typically grazed throughout the summer, in contrast to meadow which is ungrazed or used for grazing only after being mown to make hay for animal fodder. [2]
