The Mighty Eucalyptus has fallen.
Russel Norman's decision to step down from the co-leadership of the Greens is a crushing blow for a party still in recovery following its disappointing result in last September's general election. That was written across the faces of Green MPs gathered in the party's caucus room for the announcement. Their demeanour registered all the emotions between glum and glummer.
But his departure - the ex-Queenslander may yet quit Parliament altogether - should have surprised no-one.
Alongside the pressures of political life and demands on his time as leader, he and his partner have three children under the age of four. Something had to give.
There were signs after the election that all was not right. He took very badly the Greens' failure to lift their vote at a time when Labour was in a very weak state.
