PROVERBS: 'Kei whawhati noa mai te rau o te raataa. Don't pluck and fling about to no purpose the blossoms of the raataa tree! The raataa tree... produces myriads of red flowers; the small parts of these when blown off by the winds fill the air around: so, - Don't become ashamed when your lying is detected.' (Colenso 1880: 124)
George Grey interprets this saying as: ''Do not fly into a passion (get red in the face) for no cause, like the wind scattering the rata blossom.''
