Hierochloe is a genus of plants in the grass family known generally as sweetgrass.[https://www.biodiversitylibrary.org/page/2954364#page/76/mode/1up Brown, Robert. 1810. Prodromus Florae Novae Hollandiae 208-209] in Latin These are perennial rhizomatous grasses found primarily in temperate and subarctic regions of Eurasia and North America, although some species extend southwards into Australia and Latin America.[http://plants.usda.gov/java/profile?symbol=HIERO USDA Plants Profile]
These erect green grasses are known for their sweet scent. They bear panicle inflorescences with rounded grass grain fruits.[http://ucjeps.berkeley.edu/cgi-bin/get_JM_treatment.pl?8738,9048 Jepson Manual Treatment]
Some authors advocate merging the two genera Hierochloe and Anthoxanthum, though others disagree.[http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=102065 Flora of China Vol. 22 Page 336 黄花茅属 huang hua mao shu Anthoxanthum Linnaeus, Sp.
