Open standards are characteristic of some aril species. Fortunately, they tend to have strong mid-ribs. In this case, I think the open standards showcase the contrasting style arms. If this had shown up in my seedling patch, it certainly would have gone on my "watch list"!

Didn't quite hold the richness of color in the standards, but still pretty
nice colors. Not bad for the type. It's the second one to bloom from the
MACHO HOMBRE X ESTHER'S SON group and the first was an attractive yellow
with a bit less open standards. I was told years ago by a hybridizer that
MH was bad about contributing open standards, but they haven't been bad
enough on my things to prohibit using it.
