The Division of Forestry and Wildlife of the Hawai`i Department of Land and Natural Resources has designated this species as one of Hawai`i's Most Invasive Horticultural Plants.
- Medium-sized clumping grass, grows up to 3 ft tall

- Found on all main Hawaiian islands (controlled on Kaua`i, Maui, Moloka`i and Kaho`olawe); native to Africa
