The pinnae are also divided, but less distinctly, into internodes of various lengths.
Stem and branches pinnate or bipinnate, the pinnae and pinnules alternate.
Pinnae was the name given to the side wings of the soldiers' helmets, apparently formed of feathers.

The pairs of cells on the pinnae are all secund, and in contact with each other at their bases, though widely divergent above.
