Detailed description
Dense, mat-forming, coarse perennial grass. Stolons stout, long, usually reddish, occasionally with thin rhizomes. Leaves alternate, 40–100 × 4–12 mm, dull greyish to bluish green, flattened strap-like, tip hooded which splits when flattened, blades folded at base, ligule a tiny fringe, auricles missing. Sheath large, broad, with fine green and white stripes, usually has reddish tinge, with 3–4 mm hairs at blade junction. Seedhead rigid, flattened, brittle spike; seeds usually aligned to one side.
Similar taxa
Smothering growth form is similar to kikuyu (Cenchrus clandestinus). The distinctive flattened seedhead, easily separates buffalo grass from all other species.
Habitat
Terrestrial. Light demanding (West, 1996). On Raoul this grass is found on coastal areas and occasionally young plants are found along tracks through the forest and even in the wet forest (West, 1996). Smothers coastal areas (Cameron 1996).

Other information
Environmental Weed (2024)
This plant is named in a list of 386 environmental weeds in New Zealand 2024 prepared by DOC. 759 candidate species were considered for inclusion on this new comprehensive list of environmental weeds in New Zealand. The species considered were drawn from published lists of weed species, lists of plants that must be reported or managed by law if observed, existing national and regional programmes and agreements for pest management, and species already managed by the Department of Conservation (DOC). Candidate species were then assessed to see if they were fully naturalised and whether they have more than minor impacts in natural ecosystems. Read the full report here.
