Ouse Valley and downland

Field meeting reports

Meeting date: 6 July 2013

(Leader: Peter Smith)

Eleven hardy botanists gathered at Rodmell to brave what proved to be grilling heat and to visit tetrad TQ40I on the Lewes levels.  With 418 species already recorded, we did well to add six more, including Puccinellia rupestris (Stiff Salt-marsh Grass) and Groenlandia densa (Opposite-leaved Pondweed).  We also enjoyed looking at previously recorded sites for wetland species such as Catabrosa aquatica (Whorl-grass), Trifolium squamosum (Sea Clover), Potamogeton pectinatus (Fennel Pondweed) and Ceratophyllum demersum (Rigid Hornwort). After lunch by the river, a reduced group adjourned to the equally shadeless downland tetrad of TQ40B near Telscombe.  Here we were rewarded with good sightings of Valerianella dentata (Narrow-fruited Cornsalad) and Legousia hybrida (Venus’s-looking-glass).  Fifteen new tetrad records were added.
