#Poaceae

• Arrhenatherum elatior — A historical or non-standard spelling variant for the standard scientific name 'Arrhenatherum elatius' (tall oat-grass or false oat-grass), a tall perennial grass native to Eurasia and widely utilized as a high-quality forage crop. The species is recognized for its rapid regeneration capability after mowing and its preference for fertile, well-drained soils within temperate meadows.
• Arrhenatherum parlatorei — A rare mountain or alpine grass species within the Arrhenatherum genus, family Poaceae, endemic to or distributed across certain rocky regions of Southern and Central Europe, named in honor of the Italian botanist Filippo Parlatore. The plant adapts excellently to screes and thin calcareous soils, featuring slender yet resilient stems and a fine panicle inflorescence, playing an important role in alpine meadow biodiversity conservation.
• Arundinaria — A genus of perennial plants in the Poaceae family, Bambusoideae subfamily, comprising bamboo species native primarily to the temperate regions of North America. These plants are characterized by running or leptomorph rhizomes, woody culms that often branch at the nodes, and complex inflorescences. It represents the only bamboo genus native to the North American continent, holding major ecological importance in forming canebrake habitats.
• Arundinaria gigantea — A species of large, arborescent perennial bamboo native to the southeastern United States, belonging to the Poaceae family. Commonly known as 'river cane', this plant develops vigorous woody culms that can reach heights of up to 8-10 meters, forming massive, impenetrable clonal colonies called canebrakes. It plays a critical ecological role in preventing water erosion and provides essential shelter for numerous endemic bird and insect species.
• Arundinaria hindsii — The scientific name of an erect bamboo species native to East Asia (currently known taxonomically as Pleioblastus hindsii). This perennial plant from the Poaceae family is structurally characterized by slender, rigid, dark green culms that grow densely and compactly, frequently used in landscape architecture for creating resilient natural screens and ornamental hedges.
• Arundinaria viridistriata — The scientific name of a dwarf bamboo species highly valued for its variegated leaves striped with yellow and green (currently known taxonomically as Pleioblastus viridistriatus). This ornamental plant from the Poaceae family features a low, compact structural growth pattern, making it ideal as a groundcover in partially shaded areas of urban gardens due to its bold color contrast.
• Arundo — A genus of perennial herbaceous plants in the family Poaceae (grasses), characterized by extremely tall, rigid, lignified, and knotty arundiform stems resembling bamboo. These plants grow wild or cultivated in temperate and subtropical regions, preferring moist soils along watercourses, and have been historically used for making wind musical instruments, roofing, or as biomass.
• Arundo donax — The scientific name for the giant reed (or Spanish cane), an invasive perennial grass species of the genus Arundo, native to Asia but naturalized in the Mediterranean basin and other warm regions. The plant reaches heights of up to 6-10 meters, with very thick stems used industrially to manufacture reeds for woodwind musical instruments (clarinet, saxophone, bassoon), in eco-construction, and as a major source of renewable energy.
• Arundo pliniana — A species of perennial, rhizomatous herbaceous plant belonging to the Poaceae family (grasses), native to the Mediterranean basin and neighboring regions. It is a medium-to-large-sized reed, often confused with its better-known relative Arundo donax, but structurally distinguished by thinner culms, narrower leaves, and a remarkable tolerance to compact, clayey, or dry soils. This species plays an important role in the ecology of Mediterranean slopes, preventing soil erosion through its dense root system.
• Avena — The Latin scientific name of the genus of herbaceous plants in the grass family (Poaceae), popularly known as oats; it includes widely cultivated species praised for their high nutritional qualities, such as Avena sativa (common oat), heavily used in human diet, cereal flakes manufacturing, and as forage. Structurally, the genus is characterized by straw-like stems and inflorescences in the form of a panicle composed of pendulous spikelets.
• Avena sterilis — The Latin scientific name of a wild oat species in the grass family (Poaceae), commonly known as winter wild oat or animated oat. It is an annual herbaceous plant, native to the Mediterranean region and Western Asia, but globally distributed, often considered a noxious weed in cereal crops due to its high resistance and rapid multiplication capacity via large seeds equipped with stiff hairs.
• Avena strigosa — The Latin scientific name of an oat species in the grass family (Poaceae), commonly known as lopsided oat, bristle oat, or black oat. It is an annual plant historically cultivated in areas with poor, acidic, or sandy soils in Western and Northern Europe as a forage crop or soil protection cover crop; it is structurally distinguished by its small spikelets and long, rigid, bristly awns.
