This new species is certainly one of the most distinct of the whole 
genus, It comes next to A. phegopteroidea Hook., but the glabrous sur- 
faces, winged rachis, stalked and very obtuse pinnae and the mostly simple 
veins mark it clearly. The specific name is taken from the resemblance 
of the black, thick basal scales to a small whalebone. The brown hairs 
of the lower side of the rachis leave when falling small elevated points, 
the rachis thus becoming slightly muricate.
