Description from GrassBase.

Habitat/ecology:  Reportedly introduced as a pasture grass to Wallis and Futuna and now a widespread grass on Wallis (Warea Orapa, pers. com.). In Fiji, "covers large areas from sea level to about 300 m., being very common especially in the dry zones, in pastures, canefields, waste places, and along roadsides. It is an important pasture grass in the dry zone of Viti Levu and in some dry areas it is also used as a lawn grass. Unfortunately, it also becomes a weed of cultivation and waste places" (Smith, 1979; pp. 383-384). Introduced in Guam, "locally persistent, in fields, but not common" (Stone, 1970; pp. 230-231).
