Substratum: soil.Place: Zadnja Trenta valley, next to the upper Soa stream near its spring and below Soa trail; near the mountain cottage Koa pri izviru Soe, East Julian Alps, Posoje, Slovenia EC. Comment: There are quite a few richly and beautifully flowering trees growing in Julian Alps. Alpine Laburnum (Laburnum alpinum) is certainly one of them, if not the nicest one in spite of the fact that it never grows into a large tree. Its golden 'waterfalls' of flowers remain permanently in our consciousness. Although this South European species is widely distributed and quite common, one usually finds solitary trees scattered among other trees of light alpine woods. However, the site pictured here is unusually rich with these jewels. The mountain slopes ascending above blue and wild waters of Soa river are unforgettable in May.Ref.:(1) M.A. Fischer, W. Adler, K.
