Hazel (Corylus avellana ) catkins, the lambs tails, in the Serpentine Walk. These are the male catkins which produce the pollen.
These are the female flowers with the red styles and stigmas.The stigmas catch the pollen and eventually form the hazel nuts in the Autumn, however, the pollen has to be from another hazel tree.
There was a lot of lichen on the branches of the tree. The greenish yellow lichen is I think Xanthoria parietina but there are also some other species present.
