YNU Botanical Section Reports 2017

摘要

As in previous years, much of the effort in 2017 was directed towards recording for the forthcoming Atlas 2020 and many of us were directed in our botanising by geographical, rather than botanical considerations. This strategy, however, did yield someinteresting plants, with records for Smooth Stonewort Nitella flexilis (P.J. Cook) and Shore Horsetail Equisetum x litorale at Hagg Wood, Dunnington, a fine display of Marsh Fern Thelypteris palustris at Kelleythorpe and a visit to Hornsea in October which recorded 240 different taxa within a single square kilometre, Fat Duckweed Lemna gibba being one of the star finds.
