Pteridium aquilinum, Roborough Down
Pteridium aquilinum extra floral nectaries
Description:

The young bracken frond has something of the appearance of an eagle which is presumably the origin of the name 'aquilinum'. The reddish-brown colour of the tip of the frond is caused by cinnamon coloured hairs. Bracken has extrafloral nectaries that secrete sugars and amino acids; they are visible as green 'bumps' in the second image. They were first described by Darwin in 1877 and their function may be to attract ants that perform a protective function.
