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]

Contents

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]
