A closer crop of the image above.



The red azaleas in front of my house are in full bloom today.

The anthers of flowers in family Ericaceae always interest me. They form pores at the tips, and the pollen comes out of the pores.

It looks in this picture like the pollen has been caught falling out of the pores. In a sense it has, but the falling is very slow motion. The pollen is slightly sticky, and assemblies like you see here will remain almost unchanged for hours. Some of the pollen grains appear completely separated from the main mass. It is an illusion -- there is just a little bit of sticky stuff joining them.

Hope you enjoy!

I like the image but I'm not totally convinced about the grouping. A single anther, or a group of two + one, would be more pleasing to my eye.

More importantly it has given me the motivation to go out and work on something similar which, to me at least, is a major reason for being a member of forums like these Smile

I tried a single anther; that seemed boring. Two + one would have been nice, but there were no such arrangements available in these flowers. I suppose I could have done an artificial arrangement, but that seldom occurs to me with stuff as small as this --- and sure enough, it did not in this case.
