“ The laburnum has highly poisonous properties. The roots taste like liquorice, which is a member of the same family as the laburnum. It has proved fatal to cattle, though hares and rabbits eat the bark of it with avidity (Gardener’s Chronicle, 1881, vol. xvi. p. 666) . The seeds also are highly poisonous, possessing emetic as well as acrid narcotic principles, especially in a green state. ”
