Rhinanthus angustifolius

This annual root-parasite was formerly a widespread weed of arable land in E. Britain. However, most of the remaining sites are on the North Downs, in grassland and open scrub on chalk. In Lincolnshire, it occurs on peat in an area of cleared Pteridium and on railway ballast. In Angus, a tiny colony survives in sandy coastal grassland. Lowland.
