Description

Title:
Marsh Willowherb flowers [UV]
Caption / Description:

Ultraviolet photograph of Epilobium palustre (Marsh willowherb) in flower.

The flowers exhibit a darker area around the centre when photographed in UV. This marking is known as a nectar guide or pollen guide as it may help insects (which can see UV light) easily find the part of the flower with nectar / pollen. In turn, this makes it more likely for the flower that it will be polinated by a visiting insect.

The flowers are very small, approx 0.5mm in diameter.They have four light pink petals with a notch in the centre edge of each petal. The seed capsules are several centimetres long and covered in short fine hairs.
