Salix cinerea, Grey Willow

...is opening up now, as is Osier, Salix viminalis. I know these two particular trees from last year, so it's good to know the species before seeing this stage of development. Also I will add Meadow Thistle, Cirsium dissectum, whose spoony leaf I now recognise. These two take the list to 220, and the vascular plant list to 50 - 25% of target.
