Lathraea squamaria (Toothwort)
An annual or perennial herb, parasitic on the roots of a range of woody plants, especially Corylus, Fraxinus and Ulmus glabra. Its typical habitats include deciduous woodland, hedgerows, and river and stream banks. Generally lowland, but reaching 350 m at Alston (Cumberland).
The distribution of L. squamaria is similar to that shown in the 1962 Atlas. There have been 10-km square losses throughout its range, the reasons for which are unclear.
European Temperate element; also in C. Asia.
Boundary and linear features (eg hedges, roadsides, walls)
