Fern allies are a diverse group of seedless vascular plants that are not true ferns. Like ferns, a fern ally disperses by shedding spores to initiate an alternation of generations.
Famous quotes containing the word ally:
“If Germany is to become a colonising power, all I say is, God speed her! She becomes our ally and partner in the execution of the great purposes of Providence for the advantage of mankind.”
—W.E. (William Ewart)
