''Laburnum anagyroides'', the common laburnum, golden chain or golden rain, is a species in the subfamily Faboideae, and genus ''Laburnum''. ''Laburnum alpinum'' is closely related. It is native to Central and Southern Europe. The plant grows and flowers in damp and mild habitats, especially in the calcareous soils of Southern Europe. == Description == The plant is a small deciduous tree or large shrub up to tall. It has smooth bark, dark green spreading branches and pendulous and pubescent twigs. The leaves are generally trifoliate and oval with long petioles, smooth on the upperside and hairy on the underside.〔Kilbracken, J. 1995. ''Easy way guide Trees.'' Larousse. ISBN 0-7523-0027-X〕 ''Laburnum anagyroides'' blooms in late spring with pea-like, yellow flowers densely packed in pendulous racemes 10-25 cm (4-10 in) long. The flowers are golden yellow, sweet scented, and typically bloom in May. The seeds are legumes with large numbers of black seeds that contain cytisine, an alkaloid extremely poisonous to humans as well as goats and horses, especially when not ripe. However, some wild animals such as hares and deer can feed on them without any problems, and because of this the plant is believed to have magic properties in some regions. All parts of the plant contain cytisine and are poisonous if consumed. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Laburnum anagyroides」の詳細全文を読む スポンサード リンク
