Quick Facts Hymenachne, Scientific classification ...

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]
