An old and mysterious record of Senecio paludosus from v.c. 20

摘要

Researchers compiling data on Senecio paludosus (Fen Ragwort) for conservation programmes came across a specimen of this rare plant buried in the herbarium of the Royal Botanic Garden, Edinburgh, claiming to come from Hertfordshire. However, it was not until Dr Stuart Warrington of the National Trust drew my attention to this reference that news of its existence surfaced. The specimen was reputed to have been collected in 1932 in a gravel pit at Ware, Hertfordshire by persons unknown.
