Lachnagrostis filiformis (
syn.Agrostis avenacea) is a species of
grass known by the common names Pacific bent grass, New Zealand wind grass, fairy grass,[2][3] or blown-grass.[2] It is native to
Australia,
New Zealand, and other Pacific Islands including
New Guinea and
Easter Island. While it is found in a wide variety of habitats, it seems particularly invasive in areas with damp soils, such as areas near bodies of water.[4] It has been introduced to
southern Africa,[5] the
United Kingdom,[6]Taiwan, the southern
United States and
Mexico.[7]
Pacific bent grass is a tufted perennial grass growing up to 65 centimeters tall. The leaf blades are flat and about 8-25 centimeters long and 2-3 millimeters wide.[4] The stems, which are round or polygonal, are hollow.[6] The
inflorescence, which appears in June and July, may be from 7-30 centimeters long. It consists of a panicle of wispy strands, each with several tiny, fuzzy spikelets at the end. The spikelets are two or three millimeters long.[8]
In Australia it is a fire hazard,[3][9][10] and interferes with trains.[11][12]
