 I have not the slightest hesitation about separating this plant from A. 

 auriculatum Sw., for not only the shape of the pinn«, and the cutting of 

 them, but the venation is different in the two. Also I think the stipes of 

 A. auriculatum, are the shorter, and the scales on them are pale drab instead 

 of rich brown, with darker centres ; they are not so broad and ovate as those 

 on A. marginatum, and they do not extend so far up the stipe and rhachis. In 

 A. marginatum, there are fibrillose or hair-like scales mixed with the broad ones. 

 The rhizomes of both species are erect or suberect, and stipes densely tufted. 

 A. auriculatum is thinly herbaceous in texture, and dries a dull dark green 

 colour : A. marginatum is very coriaceous and shiny, with a metallic sheen 

 on the upper surface. The under surface of A. auriculatum is nearly glabrous, 

 having only a few small linear scales on the costa : that of A . marginatum 

 is always more or less covered with a myriad of very minute pellate or broadly 

 ovate, sbort, brown, adpressed scales, situated on the veins and veinlets, which, 

 without a lens, look like mere dots : but on some large fronds I see fibrillose 

 or chaffy scales, like those on A, lentum, Don (see below). The " Synopsis " 

 says the lower veinlets of A. auriculatum are in groups of three, but nothing 

 as to those of A. marginatum. I find that the system of venation is quite 

 different in the two plants. In A. auriculatum the veins are obscure on the 

 upperside ; but they can be made out on the underside in youog fronds, and
