spikelets. S. africanus also differs from S. fertilis by larger
spikelets and by the inflorescence branches being more appressed at the base.
mainly coastal distribution from Brisbane, Qld to Adelaide, S.A.. Also in Tas.
and coastal areas around Perth, W.A.; New Zealand, southern Africa, and the
Pacific region. Of African origin, is weedy in Australia, growing in lawns,
sports grounds and along roadsides and forms wiry tufts when mown. Widespread
in stressed areas of farms (yards, gateways etc). It poses a minor problem to
pastoralists in subtropical coastal eastern Australia; flowers all year, but
mostly spring to autumn.
