This species has been passing for A', simiata var., but it is 

 so uniform in its growth and differs so widely from N. siruiata 

 that it deserves specific rank. It is uniformly very narrow with 

 small pinnae, in marked contrast to those of A^. sijiuata, and has 

 the lower surface covered with obtuse scales, whereas A', siiiuata 

 has lanceolate, acute scales.
