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 poison frog semiopaca", "C. rugiceps" and "C. sp. A". Other related toxins, histrionicotoxin and pumiliotoxin, are found in frog species from the genus "Dendrobates". The golden poison frog, like most other poisonous frogs, stores its poison in skin glands. Due to their poison, the frogs are deterrent to predators; "P. terribilis" poison probably kills any predator, except for one snake species, "Liophis epinephelus". This snake may be resistant to the frog's poison, but is not immune (Myers & Daly, 1978). The poisonous frogs and birds themselves are perhaps the only creatures to be immune to this poison. Batrachotoxin attacks the sodium channels
