It has been suggested that Angiopteris sparsisora is of hybrid origin because it putatively is intermediate between Angiopteris and the formerly independent Archangiopteris, but this has not yet been proven to be the case. This species is, however, one of the reasons why it is difficult to draw a clear morphological distinction between the two genera, and (apart from the molecular evidence provided by Murdock, Amer. J. Bot. 95: 626-641. 2008) it is a further reason to merge Archangiopteris with Angiopteris.
