The species are "Laburnum anagyroides"—common laburnum and "Laburnum alpinum"—alpine laburnum. They are native to the mountains of southern Europe from France to the Balkans. Some botanists include a third species, "Laburnum caramanicum", but this native of southeast Europe and Anatolia is usually treated in a distinct genus "Podocytisus", more closely allied to the "Genisteae" (brooms). The "Laburnum" trees are deciduous. The leaves are trifoliate, somewhat like a clover; the leaflets are typically long
Manchineel to an apple, are green or greenish-yellow when ripe. The fruit is poisonous, as is every other part of the tree. All parts of the tree contain strong toxins, some unidentified.

Standing beneath the tree during rain will cause blistering of the skin from mere contact with this liquid (even a small drop of rain with the milky substance in it will cause the skin to blister). The sap has also been known to damage the paint on cars. Burning the tree may cause ocular
