Melic
''Melica'' is a genus of perennial grasses known generally as melic or melic grass. They are found in most temperate regions of the world. Melic grasses are clumping to short- rhizomatous grasses. They have flowering culms up to tall bearing spikelets of papery flowers. The spikelets have between one and seven fertile flowers with a rudimentary structure at the distal end composed of one to four sterile florets. Some species of melic have corms, lending them the name oniongrass. The genus is most diverse in South America and temperate Asia. Eight species are endemic to China. In North America, most species occur west of the Mississippi River, with exceptions being ''Melica mutica'' and ''M. nitens'' which occur throughout much of the southeast and lower Midwest respectively. Species Species and hybrids include: * ''Melica altissima'' L. – Siberian melic grass * ''Melica amethystina'' Pourr. * '' Melica animarum'' Muj.-Sall. & M.Marchi * ''Melica argentata'' É.Desv ...

Taeniatherum Caput-medusae
''Taeniatherum'' is a genus of Eurasian and North African plants in the grass family known by the common name medusahead. The only recognized species is ''Taeniatherum caput-medusae'' and is native to southern and central Europe (from Portugal to European Russia), North Africa (Algeria, Morocco, Tunisia), and Asia (from Turkey and Saudi Arabia to Pakistan and Kazakhstan). It is also naturalized in southern Australia, Chile, and parts of North America. This aggressive winter annual grass is changing the ecology of western rangelands in North America.Zimmerman, J.R., et al. Medusahead: Economic Impact and Control in Nevada.' University of Nevada-Reno Fact Sheet FS-02-37. It was first observed in the United States in Oregon in 1903 by Thomas Howell. Forty-eight percent of the total land area of the United States is rangeland, pastureland, national parks, nature preserves, and other wildlands.
