I've always just called them "haft markings" or
"haft marks...along the beard" or some such.
Some irises are enhanced by them. Others
repell. It just depends on the neatness and the biases of the
The more extreme ones result from nearly solid
"umbrata" fall overlays, using the term Linda Mann has introduced. The
opposite extreme of "umbrata" are the butterfly wing veinings covering the
fall. The trait comes from *Iris variegata.* I suspect all
expressions of the markings you show are variations of the umbrata
Most umbratas are bitone, but this one seems to
have such intense coloration in the standards it comes off as a self.
The amoena from Meek in a subsequent post in response to yours has both the
Progenitor "I-sub-s* inhibitor *and* the umbrata, as do many of the very dark
bitones and bicolors.
