I have not the slightest hesitation about separating this plant from A . 
auriculatum Sw., for not only the shape of the pinna?, and the cutting of 
them, bat 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 veiy 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, short, 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 y 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 fin’d 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 m young fronds, and
