Hi Amy
I'll add my two cents worth. The stigma lip is where the style arm curves.
Imagine you are a bumble bee crawling down the throat of an iris and on your
back is pollen your picked up from a previous flower. As you crawl down,
your back rubs aginst the stigma on the style arm and bends it slightly
forward and in so doing deposits pollen on the back of the stigma lip. Run
your finger down the style arm, you'll soon find the stigma lip.
The pollen on the anther looks more grainy than fluffy to me. However not
all cultivars produce pollen, and some do only infrequently. If the anther
looks truncated at all, the plant iss probably pollen sterile. If you can
see two paralell creamy lines on the anther and they look very smooth, then
either the flower is newly opened and the pollen hasn't yet been released or
if the flower has been open for a day or more, that bloom isn't going to
give you pollen. Sometimes the anthers look grainy(pollen released) as soon
as the bloom opens, sometimes you must wait a day depending on the cultivar
and weather conditions. I find that as long as the weather has been fine the
pollen can be harvested any time over a period of several days, once it is
released. I prefer the to pollinate the pod parent as it is opening
especially in hot dry weather. But I think I might try the spit technique
this spring on some older blooms to see what that does.
