Where does the nectary end? Good question. My educated guess would say where the fuzzy part ends, or where the fuzzy part changes to a different texture. But even that doesn't really hold from flower to flower.
The botanical definition of a nectary is "a tissue or organ which produces nectar". Well that sure clears things up
. I've observed butterflies on lilies before, and they seem to "lick" all over the petals....
I still think your first pic here

shows a wider V than any other so far.
It's fairly easy to see where the nectaries end on this flower of yours

But on others, yes, very difficult.
dellac said:I'm also wondering if parallel ribbing is a necessarily restricted feature of petals because of the way they must accomodate sepal edges in closed buds, whereas sepals lack the feature....
Oh boy, and I though I had an inquiring mind! My thought is yes, petal ribs could be more pronounce due to the "accomodating feature", but no, I don't think it is exclusively in petals and not sepals. Both can have more than just the two ribs that we have talked about so far.
dellac said:Oh... I'm reducing file size (and picture quality) to take account of Anthony's ultra-slow download speeds....
Even so, the photo detail is better then the first pic that brought on this V talk. Dave has some kind of parameter here on the ATP forums that automatically reduces them if they file size is too large. What "too large" is, I don't know.
