Michael, are you sure the first image (uper line to the left) is not A. concinnum???
Yes, I think it is just a sun form. The two have been confused in the past. See the notes in Hirai, R.Y. and Prado, J., 2019. Neotropical species of the Adiantum raddianum group (Pteridaceae). Willdenowia, 49(3), pp.295-317.
I carefully studied this article, but at least the illustration on p. 314 is irritating…
