Plant Genera


Family Code: POACEA
Genus Code: HYMEN8
Genus CN: marsh grass
Genus Authority: P. Beauv.
Genus Summary: A genus of 5-10 species, perennials, of the Neotropics and Paleotropics. Acosta et al. (2014) show 2 clades of Hymenachne, rendering it non-monophyletic, and suggest that it may need to be split in the future. If it is split, it appears that our two species would be in separate genera, with Hymenachne hemitomon (the former Panicum hemitomon) moving to yet another new genus. Hymenachne has a C3 photosynthetic pathway.
