The genus Antrophyum, established by Kaulfuss in his valuable Enumeratio Filicum, is well 



an involucre, always, we believe, following the 



distinguished from Hemionitis by the presence of an 



lines of the veins, although in some species the veins themselves are scarcely visible when not 



rendered so by the presence of the fructification. 



Thc present plant, for specimens of which, from the Isle of France, we are indebted both to 

 Captain Carmichael and to A. B. Lambert, Esq., is remarkable in having the lines of fructification 

 immersed in the very substance of the frond.

Our specimens vary in size, but they are all larger than those described by Willdenow.
