Oplismenus hirtellus ssp. undulatifolius
Wavyleaf basketgrass forms dense mats under a deciduous forest canopy. The mats are so dense that native vegetation, including tree sprouts, cannot grow. It has been noticed in Maryland. There is a strong concern that it will become a serious problem in the southeast if nothing is done. Please watch out for wavyleaf basketgrass.
Wavyleaf basketgrass is a grass which trails along the ground by branching out at stem nodes. The leaf blades (½” wide, 1½ - 4” long) lie flat on the ground and are wavy, hence the name, and taper into a sharp tip. The leaf sheaths and stems are hairy. Its flowers bloom in the fall and have pointy tips. The seeds disperse by sticking to passing wildlife and people.
