Not considered rare in Victoria in the wild state, but considered threatened: regeneration is problematic or less than necessary to replace losses, and the populations are continuing to decrease. This category is used predominantly for plants that may occur over their former range but are markedly less common and continuing to decline, and also for those plants whose range is now substantially reduced with satisfactory regeneration only in a very small proportion of that range
