Hawaii - Asplenium

Another important genus of ferns in Hawaii is Asplenium. This group is found throughout the tropics, and there are several species in the Hawaiian islands. Asplenium species have linear sori, which can be found in other genera as well, but they can help you figure out if something could be an Asplenium:

The overall shape of the pinnae in Asplenium can also help to identify them. They are usually once pinnate to twice pinnate, or anywhere in between, as you can see in the photos below.
