ROYAL FERN; FLOWERING FERN:

Fronds 2 to 6 feet tall^ growing in clumps^ often 

 in shallow water^ twice pinnate^ the large and 

 rather distant pinnae and pinnules giving them a 

 light and airy appearance; sterile and fertile 

 fronds alike, except that in the latter the upjjer 

 pinnae are changed into spore-bearing organs.

 tributed.
