Cynosurus cristatus, Crested dog's-tail, is a short-lived perennial grass in the family Poaceae, characterised by a seed head that is flat on one side. It typically grows in species rich grassland. It thrives in a variety of soil types but avoids the acid and calcareous extremes of pH, and prefers well drained soils.[1] It may be grown as an ornamental plant.[citation needed]

It is also known as crételle (French) and Wiesen-Kammgras (German, meaning meadow comb-grass). The Latin Cynosurus cristatus means 'addled crested or tufted'.[citation needed]

Locations[edit]

Seed head

Most parts of Europe, South West Asia, introduced into North America, Australia and New Zealand, from near sea level up to about 2000 feet, in all soil types.

Flowers[edit]

June to August

Identification[edit]

The anthers and stamen in the flower head
The ligule is blunt
The lower side of the leaf is smooth, glossy and keeled

It is perennial with a slighted tufted habit, a slender stem, 15 to 45 cm high, leafy at the base and thus suitable for grazing by sheep.

The spikelets are fertile or sterile, mixed within the same cluster. They are oblong or wedge shaped, 3–6 mm long, with 2 to 5 flowers.

The ligule is blunt. Leaves are folded in shoot.

Leaves are pointed at the tip, flat (not boat-shaped). The lower side of the leaf is smooth, glossy and keeled. The upper side is ribbed. Other grasses with glossy leaves include Lolium perenne and Poa trivialis.

Uses[edit]

Grazed by sheep as it is leaf at the base. It can withstand the cold and drought and remains green during the winter. Cattle and sheep will eat the young leaves eagerly, but leave the stiff, hard stems alone.

It has been used for straw plaiting hats and other similar uses.

Foodplant for Skipper (butterfly) and brown butterfly families. It also use as a rat killer.
