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]
Lachnagrostis filiformis is known elsewhere as an introduced species and sometimes a noxious weed. It is particularly invasive in California , where it is a weed of sensitive vernal pool ecosystems around San Diego.[13]
