Herringbone Ferns - almost 200 years apart.

 Blechnum spicant

Also known as  herringbone fern, fishbone fern and hard fern.

Nearly 200 years earlier:

These are the pressed herbarium sheets of Robert Dick, baker and botanist of Thurso 1811-1866.

He described Dunnet Head as being a forest of ferns.
