Macrochloa tenacissima

Macrochloa tenacissima, synonym Stipa tenacissima, (esparto, esparto grass, halfah grass, alfa grass, or needle grass) is a perennial grass of northwestern Africa and the southern part of the Iberian Peninsula. Phylogenetic and morphological evidence indicated that the species did not belong in Stipa, and recent sources treat the species as Macrochloa tenacissima as a result.
