Agrostis capillaris, the common bent, colonial bent, or browntop, is a rhizomatous and stoloniferous perennial in the grass family (Poaceae). It is native to Eurasia and has been widely introduced in many parts of the world. Colonial bent grows in moist grasslands and open meadows, and can also be found in agricultural areas, roadsides, and invading disturbed areas.
The name Agrostis comes from the Greek word meaning forage plant, agros meaning "a field".
A links is the oldest style of golf course, first developed in Scotland. Links courses are generally built on sandy coastland that offers a firmer playing surface than parkland and heathland courses.
The word "links" comes via the Scots language from the Old English word hlinc: "rising ground, ridge" and refers to an area of coastal sand dunes and sometimes to open parkland; it is cognate with lynchet. "Links" can be treated as singular even though it has an "s" at the end and occurs in place names that precede the development of golf, for example Lundin Links in Fife. It also retains this more general meaning in standard Scottish English. Links land is typically characterised by dunes, an undulating surface, and a sandy soil unsuitable for arable farming, but which readily supports various indigenous browntop bent and red fescue grasses. Together, the soil and grasses result in the firm turf associated with links courses and the "running" game. The hard surface typical of the links-style course allows balls to "run" out much further than on softer turf course after a fairway landing. Players often aim to land the ball short of the green allowing it to roll up onto it rather than landing it on the green in the more targeted-landing style used on softer surfaces.
