Isachne is a widespread genus of tropical and subtropical plants in the grass family, found in Asia, Africa, Australia, the Americas, and various oceanic islands.[https://www.biodiversitylibrary.org/page/2954352#page/64/mode/1up Brown, Robert 1810. Prodromus Florae Novae Hollandiae 196] in Latin[http://www.efloras.org/florataxon.aspx?flora_id=1050&taxon_id=116518 Isachne.] Flora of Taiwan: Gramineae. They may be known generally as bloodgrasses.[http://plants.usda.gov/java/profile?symbol=ISACH Isachne.] USDA PLANTS.

These are annual and perennial grasses. The stems are hollow, the leaves are often nerved, and the inflorescence may be an open or narrow panicle. The spikelets are rounded to spherical. Many species are aquatic. Isachne globosa is a weed of rice cultivation.Watson, L. and M. J. Dallwitz. 1992 onwards.
