[Microlaena stipoides (Labill.) R. Br.]
This wiry, perennial tufted grass is common in moist and wet habitats. It invades disturbed sites rapidly. The awned fruit are dispersed on clothing or animal fur. It is a fire-stimulated grass and in Hawai'i carries fires over larger areas than normal. It has not been evaluated for biological control.
It grows between 100-1,500 m in dry to mesic areas. There are major infestations from Puna to South Kona on Hawai'i.
