This species, which is not very abundant in Britain, is one of the 
most easily recognised members of the genus.- The pinnules are 
small, distant from one another, the lobes being relatively broad, the 
margins usually undulating, or slightly crenate, and the lateral nerves 
very distant from one another, with a few very wide dichotomies.
