Although it is a week before I leave on vacation, from now until my return in mid-April the written accompaniment to many of the daily photographs will be shorter than usual. – Daniel
If you’ve keen eyes, you will note that there are both male and female flowers in this photograph. The long catkins are inflorescences containing many dozens of pollen-producing male flowers, while the small dots of pink here and there are the stigmas (or pollen-receiving structures) of the small, wind-pollinated, apetalous female flowers (apetalous = lacking petals). If you’re not certain what you’re looking for, the Arkive site mentioned a few days as a resource link has this photograph of a Corylus female flower.
