Sven HeinzHello,

i found these star-shaped formations on leaves of Forsythia. Does anyone know what this could be? The diameter is 300 µm.

Re : star-shaped formations
These are stellate hairs of the leaves, Surely of Forsythia?

Here are pictures of Deutzia:

Re : star-shaped formations
Thanks that fits! I am absolutely certain that it is Forsythia. On some leaves there are very few stars, on others there are many.

Hairs on Forsythia leaves would be new to me.
