A root parasite mainly found on species of Alnus, Salix and Populus. It usually occurs in damp, shaded places in open woodland, coppices and along hedgerows, and especially near stream and river margins where dispersal may be effected by flood water. Lowland.
L. clandestina was introduced to cultivation in Britain around 1888. It is grown in gardens as an attractive curiosity, from where many populations are likely to have originated. It was first reported from the wild in 1908 at Coe Fen (Cambs.), where it was probably deliberately planted and where it still survives.
A Suboceanic Temperate species, native to Belgium, France, Spain and Italy.
