Well, Arlyn's a LONG way from being an expert at ANYTHING, let alone iris ID.....but I do "try" a lot ! Keep in mind, that for ID photos, you want to see the 'whole" flower", and all it's "parts". So, one showing the whole stalk, with the "branches", and buds. One of the bloom "from the side "( much as the one of your "cemetery" iris") , will show how much "flare" the falls have. One "face on" to the falls.like this:
gives a good idea of the shape of the falls....long and skinny, rounded, oval shaped, fiddle shaped...whatever.
One of the beard, and haft area will make the reticulatins (those "squiggly lines") easy to see, exactly how the beard is shaped, and colored.
One "straight down", like this:
shows the color and shape of the "style arm area.
and it all helps ! Then, when you THINK you have nailed down a 'possible".....we can move on to the next steps in the process.
