Notes. Eremopyrum
triceum is recorded as being present in N.S.W. (Hnatiuk, 1990), but was not
treated in the Flora of New South Wales (1993). Its inclusion here is based on
a single specimen which may have escaped from cultivation. This species does
not appear to have become naturalised in Australia. Flowers: Nov.
