European alder - Spring blossom series

The European alder (also called Black alder, Common alder) has separate male and female inflorescence that bloom at the same time.  The long catkin type male inflorescence can be seen in the image above while the small red female inflorescence can be seen in more detail in the image below.
The female inflorescence goes on to develop into the small "cone" like seed pods that are characteristic of this tree species.
