On the Hunt For Nectaries-Origin of Honey

Himalayan Blackberry is nearing the end of its bloom- as it started early, it is ending early too. Plants near my house appear to be 3/4 done- but the bees are pouring out of the hives. Last year and this year I got curious as to exactly where it was the bees are feeding from when they put their heads in into a blackberry flower, and so did some reading. Also, some digital microscoping, as shown below.

There is an interesting paper by a British scientist on tracking the nectar flow in a single plan, and she also wrote a book called Floral Biology, which is on it way from Great Britain to my house as I write.

She drew out nectar with a pipette into little jars each day, like she was a bee, and then, with a refractometer, measured the sugar content. She was trying to determine when it was at its maximum, and to what degree environmental measures impacted it.

Nectar, in plants, comes from something called a nectary. It can be in lots of different places on a plant. I imagine it to be a little bump with some sort of pore that drips out nectar. And when I read her paper, as I was yet again interested to find out where these were in a blackberry, as she used her pipette 2x a day, on lots of flowers, and it can't be that hard to find (though I failed last time I tried).

Well, failed again. I looked all over the place. And there is such a tangle of stamens and pistils that I can't understand at all how she accessed anything at all. 

When I pull everything off, there's the ovary itself- or ovaries- I think this is a druplet?- and I sure don't see a dang thing that looks like it would exude nectar.

Next step is to use a higher power. Of course, a Higher Power was the one who put the dang things there in the first place, and one would think it would be really obvious. Its not.
