Psathyrostachys is a genus of Eurasian plants in the grass family. [1] [2]
Poaceae or Gramineae is a large and nearly ubiquitous family of monocotyledonous flowering plants 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.
Hordeum is a genus of annual and perennial plants in the grass family. They are native throughout the temperate regions of Africa, Eurasia, and the Americas.
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus Carex with over 2,000 species.
Stipa is a genus of around 300 large perennial hermaphroditic grasses collectively known as feather grass, needle grass, and spear grass. They are placed in the subfamily Pooideae and the tribe Stipeae, which also contains many species formerly assigned to Stipa, which have since been reclassified into new genera.
Sisyrinchium is a large genus of annual to perennial flowering plant in the family Iridaceae. Native to the New World, the species are known as blue-eyed grasses and, though not true grasses and in varieties with flower colors other than blue, are monocots.
Elymus repens, commonly known as couch grass, is a very common perennial species of grass native to most of Europe, Asia, the Arctic biome, and northwest Africa. It has been brought into other mild northern climates for forage or erosion control, but is often considered a weed.
Andropogon is a widespread genus of plants in the grass family, native to much of Asia, Africa, and the Americas as well as southern Europe and various oceanic islands.
Helictotrichon, or alpine oatgrass, is a genus of perennial flowering plants in the grass family. The genus name comes from the Greek heliktos meaning twisted, and trichos meaning spine, referring to the shape of the awn.
Achnatherum is a genus of plants which includes several species of needlegrass. Several needlegrass species have been switched between Achnatherum and genus Stipa; taxonomy between the two closely related genera is still uncertain.
Elymus is a genus of perennial plants with approximately 150 species in the grass family, related to rye, wheat, and other widely grown cereal grains.
The flora of Australia comprises a vast assemblage of plant species estimated to over 20,000 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.
Eremopyrum is a genus Eurasian and North African plants in the grass family. One species, Eremopyrum triticeum has become widely established as a weed in parts of North America.
Taeniatherum is a genus of Eurasian and North African plants in the grass family known by the common name medusahead.
Pentanema is a genus of Asian and African plants in the elecampane tribe within the sunflower family.
Cousiniopsis is a genus of flowering plants in the daisy family.
Psathyrostachys juncea is a species of grass known by the common name Russian wildrye. It was formerly classified as Elymus junceus. It is native to Russia and China, and has been introduced to other parts of the world, such as Canada and the United States. Psathyrostachys juncea is a great source of food for grazing animals, as it has high nutrition value in its dense basal leaves, even in the late summer and autumn seasons. This species can grow and prosper in many harsh environments, making it an ideal candidate for improvement as it can grow in areas were farming is difficult. This species is a drought-resistant forage plant and can survive during the cool seasons. It is also a cross-pollinator and is self-sterile. This means that P. juncea cannot self-fertilize; it must find another plant of the same species with which to exchange gametes. Self-sterilization increases the genetic diversity of a species.
Kengyilia is a genus of Asian plants in the grass family. The genus is named in honor of Yi Li Keng.
Leymus akmolinensis is a species of grass endemic to Russia and Kazakhstan.
GrassBase is a web-based database of grasses, continually maintained and updated by the Royal Botanic Gardens, Kew.
Stellera is a genus of flowering plant in the family Thymelaeaceae, with a single species Stellera chamaejasme found in mountainous regions of Central Asia, China, Siberia and South Asia. S. chamaejasme is a herbaceous perennial plant with heads of white, pink or yellow flowers, grown as an ornamental plant in rock gardens and alpine houses, but considered a weed playing a rôle in the desertification of grasslands in parts of its native range. Like many others of its family, it is a poisonous plant with medicinal and other useful properties.
