Glyceria grandis | |
Glyceria grandis is a species of grass known by the common name American mannagrass. It is native to Canada and the United States, where it is widespread in distribution. It is most commonly found in wet areas such as riverbanks and ponds.
This is a rhizomatous perennial grass bearing thin stems which approach two meters in maximum height. The sturdy leaves each have a prominent central vein. The tops of the stems are occupied with spreading, multibranched inflorescences bearing many small, oval-shaped spikelets.
The hypocotyl is the stem of a germinating seedling, found below the cotyledons and above the radicle (root).
Juncaceae is a family of flowering plants, commonly known as the rush family. It consists of 8 genera and about 464 known species of slow-growing, rhizomatous, herbaceous monocotyledonous plants that may superficially resemble grasses and sedges. They often grow on infertile soils in a wide range of moisture conditions. The best-known and largest genus is Juncus. Most of the Juncus species grow exclusively in wetland habitats. A few rushes, such as Juncus bufonius are annuals, but most are perennials.
Vanaspati is the Sanskrit word that now refers to the entire plant kingdom. However, according to Charaka Samhitā and Sushruta Samhita medical texts and the Vaisesikas school of philosophy, "vanaspati" is limited to plants that bear fruits but no evident flowers. In the Rigveda, 9th Mandala, Hymn 5.10, "Vanaspati" is a deity presiding over the forest and described as the "bright golden hued Vanaspati, with its thousand branches."
This page provides a glossary of plant morphology. Botanists and other biologists who study plant morphology use a number of different terms to classify and identify plant organs and parts that can be observed using no more than a handheld magnifying lens. This page provides help in understanding the numerous other pages describing plants by their various taxa. The accompanying page—Plant morphology—provides an overview of the science of the external form of plants. There is also an alphabetical list: Glossary of botanical terms. In contrast, this page deals with botanical terms in a systematic manner, with some illustrations, and organized by plant anatomy and function in plant physiology.
Hesperostipa comata, commonly known as needle-and-thread grass, is a species of grass native to North America, especially the western third. It has a wide distribution spanning from northern Canada to Mexico.
Indigofera australis, the Australian indigo or Austral indigo, is an attractive species of leguminous shrub in the genus Indigofera. The genus name Indigofera is Neo-Latin for "bearing Indigo". Australis, from the Latin, means not “Australian” but "southern", referring to the geographical distribution of the species.
Piptatherum miliaceum is a species of grass known by the common name smilograss. It is native to Eurasia but it can be found in many other parts of the world as an introduced species and a casual weed of disturbed areas. It is a clumping perennial grass producing sturdy, erect stems that can reach 1.5 meters tall. The inflorescence is a panicle of several whorls of branches that divide into secondary branches bearing clusters of spikelets.
Poa bulbosa is a species of grass known by the common names bulbous bluegrass or bulbous meadow-grass. It is native to Eurasia and North Africa, but it is present practically worldwide as an introduced species. It is widespread in the United States and southern Canada. It was introduced to the eastern United States around 1906 and the western US in 1915 as a contaminant in shipments of alfalfa seed. It was intentionally planted on both the east and west coasts to control weeds and prevent erosion. Today it is a common grass across the continent and is a noxious weed in some areas. It is a sturdy, hardy, persistent, aggressive grass that easily outcompetes many other plants and becomes the dominant species in disturbed habitat types, such as overgrazed fields.
Poa glauca is a species of grass known by the common names glaucous bluegrass, glaucous meadow-grass and white bluegrass. It has a circumboreal distribution, occurring throughout the northern regions of the Northern Hemisphere. It is also known from Patagonia. It is a common grass, occurring in Arctic and alpine climates and other areas. It can be found throughout the Canadian Arctic Archipelago in many types of habitat, including disturbed and barren areas.
Poa howellii is a species of grass known by the common name Howell's bluegrass.
Poa leptocoma is a species of grass known by the common names marsh bluegrass and western bog bluegrass.
Poa macrantha is a species of grass known by the common names seashore bluegrass and large-flowered sand dune bluegrass. It is native to the west coast of North America from Alaska to northern California, where it grows in sand dunes and other beach habitat.
Poa unilateralis is a species of grass known by the common names San Francisco bluegrass, ocean-bluff bluegrass, and sea-bluff bluegrass.
Puccinellia parishii is an uncommon species of grass known by the common names bog alkaligrass and Parish's alkali grass. It is native to the western United States, where it is known from a few locations in Arizona and New Mexico, and one occurrence each in California and Colorado.
Sporobolus airoides is a species of grass known by the common name alkali sacaton. It is native to western North America, including the Western United States west of the Mississippi River, British Columbia and Alberta in Canada, and northern and central Mexico. It grows in many types of habitat, often in alkali soils, such as in California desert regions.
Sporobolus cryptandrus is a species of grass known as sand dropseed. It is native to North America, where it is widespread in southern Canada, most of the United States, and northern Mexico.
Sporobolus flexuosus is a species of grass known by the common name mesa dropseed. It is native to western North America, where it can be found in the deserts and woodlands of the Southwestern United States and Northern Mexico.
Ventenata dubia is a species of grass known by the common names North Africa grass and wiregrass. It is native to southern Europe, North Africa and the Middle East. It is becoming well known in North America, where it is an introduced species and a noxious weed of cultivated and disturbed habitat. It is problematic in the Pacific Northwest, where it was first identified in Washington in 1952 and Idaho in 1957. It was found in Utah in 1996. It probably spreads when it gets mixed in with grass seed and is transported and inadvertently planted.
Vulpia microstachys is a species of grass known by the common names small fescue and small sixweeks grass. It is native to western North America from British Columbia to Colorado and New Mexico to Baja California, where it grows in many types of open habitat, including grasslands. It is dominant on some grasslands of California, and it was probably an abundant native grass before the habitat was altered by invasive non-native grasses. It occurs on serpentine soils with associates such as serpentine reedgrass. It is also known from parts of South America. It is an annual grass producing one stem or a clump of several stems growing up to 75 centimeters tall. The inflorescence has several open branches bearing clusters of purple-tinged spikelets. The spikelet has one to six flowers. The grass is usually cleistogamous, its flowers fertilizing themselves.
Chrysopogon aciculatus is a species of grass native to the tropics of Asia, Polynesia, and Australia at low elevations. Common names include amorseco, lesser spear grass, Mackie's pest, pilipiliula, and grama-amorosa.
