''Luzula'' is a genus of flowering plants the family Juncaceae, the rushes. The genus has a cosmopolitan distribution, with species occurring throughout the world, especially in temperate regions, the Arctic, and higher elevation areas in the tropics.〔(''Luzula''. ) Flora of North America.〕 Plants of the genus are known commonly as wood-rush,〔(''Luzula''. ) Germplasm Resources Information Network (GRIN).〕 wood rush, or woodrush.〔(''Luzula''. ) Integrated Taxonomic Information System (ITIS).〕 Possible origins of the genus name include the Italian ''lucciola'' ("to shine, sparkle") or the Latin ''luzulae'' or ''luxulae'', from ''lux'' ("light"), inspired by the way the plants sparkle when wet with dew.〔 Another etymology sometimes given is that it does derive from lucciola but that this meant a midsummerfield, or from the Latin luculus, meaning a small place; the same source also states that this name was applied by Luigi Anguillara (an Italian botanist) in 1561. These rushes are usually perennial plants with rhizomes and sometimes stolons. They generally form clumps of cylindrical stems and narrow leaves with hair-lined edges. The inflorescence is often a dense cluster of flowers with two leaf-like bracts at the base, or sometimes a solitary flower or a few flowers borne together. They have six brownish tepals.〔〔(''Luzula''. ) The Jepson eFlora 2013.〕 ''Luzula'' species are used as food plants by the larvae of some Lepidoptera species, including the Smoky Wainscot. Several moths of the genus ''Coleophora'' have been observed on the plants. ''Coleophora biforis'' and ''C. otidipennella'' feed exclusively on ''Luzula''. ''C. antennariella'' is limited to ''Luzula pilosa'', and ''C. sylvaticella'' feeds only on ''L. sylvatica''. ==Species== There are around 140 species in the genus: *''Luzula abchasica'' Novikov *''Luzula abyssinica'' Parl. *''Luzula acuminata'' Raf. *''Luzula acutifolia'' H.
