The following species in the grass genus Festuca, the fescues, are accepted by Plants of the World Online as of 2024. [1] This genus together with the ryegrass genus Lolium form the Festuca–Lolium complex known for its frequent hybridization, and which is further complicated by the presence of a fine-leaved fescue clade within Festuca that appears to be sister to a clade consisting of Lolium ...
Lolium perenne, common name perennial ryegrass, [1] English ryegrass, winter ryegrass, or ray grass, is a grass from the family Poaceae. It is native to Europe, Asia and northern Africa, but is widely cultivated and naturalised around the world.
Festuca (fescue) is a genus of flowering plants belonging to the grass family Poaceae (subfamily Pooideae). 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 . [ 2 ]
Festuca rubra, as red fescue or creeping red fescue, is cultivated as an ornamental plant for use as a turfgrass and groundcover. It can be left completely unmowed, or occasionally trimmed for a lush meadow-like look. There are many subspecies, and many cultivars have been bred for the horticulture trade.
Tall fescue is the most heat tolerant of the major cool season grasses. Tall fescue has a deep root system compared to other cool season grasses. This non-native grass is well adapted to the "transition zone" Mid Atlantic and Southeastern United States and now occupies over 35,000,000 acres (140,000 km 2). [23]
The stems of Burma reed, with flower stalks, are from 3 to 15 feet (0.91 to 4.57 m) tall, depending on soil and moisture conditions. The leaves are 8 to 10 inches (20 to 25 cm) long and hairless, except for a single line of horizontal hairs at the juncture of the upper and lower portions of the leaf.
This species was originally included within the genus Festuca, owing to the similarity of the flowers and inflorescences.However, there has been much debate since 1898 about its relationship to the genus Lolium, largely because of hybridization with Lolium perenne (species in separate genera are far less likely to form hybrids than those within the same genus).
Bromus secalinus is a species of bromegrass known as rye brome. [2] The specific epithet secalinus is Latin, meaning "rye-like". The fruits are hard, rounded glumes that appear superficially similar to the rye grain, which gives the brome its common and scientific name. The grass has a diploid number of 28.
