UFO's In My Garden - More Flowers and Bugs






Here's an Unidentified Flying Object and I've got somewhat Unidentified Flowering Objects below.



The macro on my little Canon Powerpoint  gets me pretty good closeups that can be enlarged to see things normally invisible with the naked eye.

Pictures of flowers were going to be an easy post I thought.  Until I started trying to figure out what I was looking at.  I've spent way too long trying to figure out these flower parts.  These are things I normally can't even see.  

I'm hoping I can get hold of a biologist friend who can help me with the identification of these flower parts.

The illustration at the right, from  saburchill.com, might suggest that the green nub is the stigma and the little star shaped flower at the top could be (help!) also part of the stigma or polllen grain, or ???  See also the picture of the pollen grains on the lily stigma below flower functions at science-fair-projects-encyclopedia.  [Based on the diagram below from countrysideinfo I'm going to say that the green is probably the ovary, the star the stigma, but since the same parts of different flowers come in such different guises, unless you have someone who really knows, it's hard to tell from the diagrams.  So don't assume anything here is definitive.]


You can see an impatiens pod on this website, which I'm pretty sure is a later stage of the green part of the pink impatience flower in my picture above.  At the top this link has a discussion of getting seeds from impatiens and the pictures are at the bottom. 

To the right above you can see that impatiens flower from a little further back.  It also has a thrips on it. 

I had an image of that word in my head yesterday, but couldn't get the letters in the right order, but Jeff Lowenfels discussed them in his garden column today and then I looked them up online.  I'm pretty certain that's what it is.  Here it is a little closer, but they are really tiny. 

OK, now that you know your flower parts (that was a joke), let's look at this campanula.




The diagram at right/below and the text below come from countrysideinfo, a UK site, which I think clears things up much more.  
The female parts of a flower consist of an ovary, which contains one or more ovules, a style and the stigma. The ovary is at the base of the flower.
From the ovary, extends a tubular structure called the style and on the top of the style is a surface receptive to pollen called the stigma.
The stigma can take many different forms, most of them designed to help trap pollen. There are many variations on this basic structural theme.

The curly things have to be the stigma and suggests the star shaped thing on the impatiens is also the stigma.  And yes, more thrips on the campanula.  And the parts that look like they've collapsed are probably the stamens, or male parts.

OK, one more to check out.  A pansy up close.  So, what is the white hairy stuff?  Another form of stigma?  Surely the green seed pod is growing right inside there.
