Laburnum (Cytisus Laburnum), a favourite tree in our gardens, belonging to the pea tribe and to the same genus as the broom (q.v.). It is a native of the south of Europe, and was introduced into England in the 16th century. The heart-wood is very dense and dark-coloured, resembling ebony, and is used in turnery. The leaves have a white down beneath, which, with the downiness and many-seeded character of the pods, distinguishes the tree from the so-called Scotch laburnum (C. alpinus). C. Adami is a hybrid between the laburnum and the shrubby C. purpureas, perhaps originating in a graft (q.v.). The roots and leaves of laburnum are poisonous, and the seeds dangerously so. They contain two poisonous alkaloids, cytisin and laburnin, and have a powerful emetic action.

“Therefore, since we are surrounded by such a great cloud of witnesses, let us throw off everything that hinders and the sin that so easily entangles, and let us run with perseverance the race marked out for us.”
Hebrews 12:1
