Chionochloa

The remaining species has been assessed, but the sources did not take a side. That silence does not amount to a fire-resistant rating.

The warning is strongest for the two similarly named species. Chionochloa macra, called narrow-leaved snow tussock, and Chionochloa rigida, called Narrow Leaved Snow Tussock, are both rated keep away with a substantial body of assessment behind them. Each has also received a very high flammability classification. These are separate species despite their nearly identical common names.

Fire and Emergency New Zealand gives red tussock grass, Chionochloa rubra, a high flammability classification, one step below the very high classification of the two snow tussocks. Red tussock grass is rated keep away on a handful of assessments. All members named here are grasses in the Poaceae family.

The disagreement is therefore limited: one assessed species received no verdict, while every species given a clear verdict was rated keep away. Without a fire-resistant finding for any member, Chionochloa offers no supported exception for a homeowner seeking a lower-flammability tussock.
