Lygeum is a genus of Mediterranean plants in the grass family.[4][5] It is placed in its own tribe Lygeeae, which is sister to Nardeae.[6]

The only known species is Lygeum spartum, commonly called esparto grass[3][7] or albardine.[8] It is native to southern Europe and North Africa, where its distribution includes Crete, Italy, Spain, Algeria, Egypt, Libya, Morocco, and Tunisia.[8][9] It is similar to Stipa tenacissima[10] and both species are used to produce a fiber product known as esparto or esparto grass.[11]

Description

Lygeum spartum is a rhizomatous perennial grass growing up to 75 centimeters tall.[12] The rhizome and the base of the stem are scaly.[13] The leaves are threadlike but stiff[12] and tough, measuring up to 50 centimeters long.[13] The inflorescence is made up of a few long-haired spikelets each up to 4.5 centimeters long. They are wrapped in a lance-shaped bract called a spatheole.[12] This sheath is 3 to 9 centimeters long and can have a sharp point.[13]
