Laburnum Laburnum Laburnum, sometimes called golden chain or golden rain, is a genus of two species of small trees in the subfamily Faboideae of the pea family Fabaceae. 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
Golden mantella marks. The tympanum is visible, but small. Brightly colored skin warns predators that the frog is poisonous. It is thought that the brilliant colors exhibited by the golden mantella are an example of aposematism, warning predators of the poisonous nature of the frog. The golden mantella is highly seasonal in its behaviour and remains largely inactive during the winter months of May–October. When the rains arrive and the temperature warms, frogs emerge from hiding and use small lentic wetlands for breeding. Males often call from concealed positions near a water source. The call is a rather pleasant, repeated click. The
