Festuca vivipara (L.) Sm. | |
Festuca vivipara, the viviparous sheep's-fescue, is a species of grass native to northern Europe, northern Asia, and subarctic North America. The specific epithet vivipara is Latin, referring to the florets' alteration to leafy tufts. The plant can have a diploid number of 28, 49, 56, or 63, though numbers of 21, 35, and 42 have also been reported.
Festuca vivipara is a perennial grass growing 5–20 cm (2.0–7.9 in) tall with capillary culms. The plant grows in dense tufts. The internodes are glabrous or somewhat puberulent. Dead leaf sheaths either persist or shred into fibers, while living sheaths are tinged purple and have a prominent midvein. The auricle is occasionally marked by a distinct swelling. The erose ligule is 0.2–0.5 mm (0.0079–0.0197 in) long. The setaceous leaf blades somewhat stiff, and the flag leaf blade is about 0.5–2.5 cm (0.20–0.98 in) long. In a cross-section, the leaf blade is typically 0.5–0.9 mm (0.020–0.035 in) wide and 0.25–0.6 mm (0.0098–0.0236 in) thick. In the cross-section, sclerenchyma are arranged in three large bundles and up to four smaller bundles, with adaxial sclerenchyma either somewhat developed along the margin to a thick subepidermal band. The strongly proliferous, compact panicles are 2–10 cm (0.79–3.94 in) long, with flowers as leafy tufts. The purplish spikelets are 0.7–3.5 cm (0.28–1.38 in) long. The glumes are much shorter than the spikelets and have erose margins. The lower glume is 2.0–4.5 mm (0.079–0.177 in) long with one vein, and the upper glume is 3–5 mm (0.12–0.20 in) long with three veins. The membraneous, awnless lemmas are 4–6 mm (0.16–0.24 in) long when not modified, and are strongly inrolled. [1] The paleas are absent or reduced. Lodicules are toothed when present and lack hairs. [2]
The grass flowers from July into early August.
Festuca vivipara occurs in North America from Greenland and Labrador to Alaska, growing on calcareous rock and peat, and can occur in western Newfoundland, the Shickshock Mountains, and parts of Quebec. [1] Elsewhere, the grass occurs in northern Europe and Russia near lakes and streams. [3]
Festuca (fescue) is a genus of flowering plants belonging to the grass family Poaceae. They are evergreen or herbaceous perennial tufted grasses with a height range of 10–200 cm (4–79 in) and a cosmopolitan distribution, occurring on every continent except Antarctica. The genus is closely related to ryegrass (Lolium), and recent evidence from phylogenetic studies using DNA sequencing of plant mitochondrial DNA shows that the genus lacks monophyly. As a result, plant taxonomists have moved several species, including the forage grasses tall fescue and meadow fescue, from the genus Festuca into the genus Lolium, or alternatively into the segregate genus Schedonorus.
Festuca pratensis, the meadow fescue, is a perennial species of grass, which is often used as an ornamental grass in gardens, and is also an important forage crop.
Bromus hordeaceus, the soft brome, is an annual or biennial species of grass in the grass family (Poaceae). It is also known in North America as bull grass, soft cheat, and soft chess.
Festuca rubra is a species of grass known by the common name red fescue, creeping red fescue or the rush-leaf fescue. It is widespread across much of the Northern Hemisphere and can tolerate many habitats and climates. It is best adapted to well-drained soils in cool, temperate climates; it prefers shadier areas and is often planted for its shade tolerance. Wild animals browse it, but it has not been important for domestic forage due to low productivity and palatability. It is also an ornamental plant for gardens.
Festuca occidentalis is a species of grass known as western fescue. It is native to much of the northern half of North America and is most widely distributed in the west. It is most often found in forest and woodland habitat. The specific epithet occidentalis is Latin, meaning "western".
Bromus madritensis is a species of brome grass known by the common name compact brome. The specific epithet madritensis refers to Madrid, Spain. It has a diploid number of 28.
Bromus catharticus is a species of brome grass known by the common names rescuegrass, grazing brome, prairie grass, and Schrader's bromegrass. The specific epithet catharticus is Latin, meaning cathartic. The common name rescuegrass refers to the ability of the grass to provide forage after harsh droughts or severe winters. The grass has a diploid number of 42.
Bromus ciliatus is a species of brome grass known by the common name fringed brome. It is native to most of North America, including most of Canada, most of the United States except for some portions of the South, and northern Mexico. It is a plant of many habitats, including temperate coniferous forest. The specific epithet ciliatus is Latin for "ciliate", referring to the delicate hairs of the leaf blades.
Bromus kalmii, the Arctic brome or prairie brome, is a species of brome grass. It is a native bunchgrass in the North-central and Northeastern United States, the Great Lakes region, and eastern Canada. The specific epithet kalmii refers to its discoverer Pehr Kalm.
Melica argyrea is a species of grass found in Argentina, Brazil, and Uruguay.
Bromus nottowayanus, the Nottoway Valley brome or satin brome, is a brome grass native to North America. The specific epithet nottowayanus refers to the Nottoway Valley. The grass has a diploid number of 14.
Bromus japonicus, the Japanese brome, is an annual brome grass native to Eurasia. The grass has a diploid number of 14.
Festuca brachyphylla, commonly known as alpine fescue or short-leaved fescue, is a grass native to Eurasia, North America, and the Arctic. The grass is used for erosion control and revegetation. The specific epithet brachyphylla means "short-leaved". The grass has a diploid number of 28, 42, or 44. This species was first described in 1827.
Festuca saximontana, the rocky mountain fescue or the mountain fescue, is a perennial grass native to North America. The specific epithet saximontana is Latin and means "of the Rocky Mountains". The grass has a diploid number of 42.
Rytidosperma bipartitum, the leafy wallaby grass, is a perennial species of grass found in south eastern Australia. Usually found on the heavier clay or on loamy soils in open eucalyptus woodland. The habit is somewhat variable, erect and densely tufted. The grass may grow up to 0.7 m tall.
Vulpia elliotea, known by the common name sand fescue or squirreltail fescue, is an annual grass native to the southeastern United States. Its specific epithet elliotea is named for its discoverer, Stephen Elliott.
Puccinellia fasciculata, or Borrer's saltmarsh grass, is an annual grass native to coasts of Europe and introduced to the northern east coast of North America. Its diploid number is 28.
Puccinellia laurentiana is a perennial grass which grows on gravelly seashores in south-eastern Canada. Its specific epithet "laurentiana" refers to the Gulf of St. Lawrence, where it grows.
Brachyelytrum erectum, known as the southern shorthusk or the southern long-awned woodgrass, is a perennial grass native to North America. Its specific epithet "erectum" refers to the erect culms of the grass. Its diploid number is 22.
Festuca nigrescens, also known as the alpine Chewing's fescue, is a species of grass in the family Poaceae. It was first described in 1788. It is perennial and grows in temperate biomes.
