We possess specimens of this noble Fern, of which we have only represented here some of the 

 smaller states, from the late Captain Carmichael, from M. Bojer, and Dr. Sieber, all of them desti-

tute of the fructification. In some parts of the frond, indeed, the veins are darker than in others ; 

 but on the most careful dissection, they contain no sori. Willdenow describes the fructification as

 All the species seem to possess very thickly downy roots.
