Hymenachne is a genus of widespread wetlands plants that is in the grass family. They may be known commonly as marsh grasses.[4] They are distributed in tropical and subtropical regions of Asia, the Americas, and the Pacific Islands.[5] A species from the Americas, H. amplexicaulis, is well known in other parts of the world as an introduced and invasive species.[6]

Hymenachne is similar to genus Sacciolepis. Both were formerly considered part of Panicum.[7]

Hymenachne aquatic plants frequently found in marshes and other wet habitats. Their stems are spongy with aerenchyma tissue.[7] The longest stems can reach 4 meters. They are perennial, sometimes with rhizomes. The leaves are linear or lance-shaped.[8] The inflorescence is usually a cylindrical, spike-shaped panicle, rarely with branches.[7]
