Sweet Basil growing wild in the garden must have seeded itself from last year (we never planted it).

Pollen is an unusual shape:-

Edit included stem cross section

A nice image too. That is an unusual surface, it seems to have depressions with little 'peaks'.
I''ll look it up and see what they are if possible.

Another nice interesting post my friend. :)

Hi John,
That's what I thought and the reason I decided to post it. I checked it out on PalDat and it looks exactly the same. The image under the scope was much clearer unfortunately the stack didn't turn out as good, I think I rushed it a bit. (was so excited Ha :D )

Reminded me of a pineapple.

Have you snuk-in that nice stem section.... :D

Yes I also had a peek, it's a distinctive grain once seen.

Good post as always Roldorf.

Yes if I could donate (to Micam) with anything other than PayPal, I would have done it, a very nice piece of software.

Pollen from Nasturtium but not Nasturtium:
Possibly common ragwort?

Hi David_b

Thanks for the suggestion of ragweed. It was (and is) the correct flowering time for them, however from what I could find on the internet the Ragweed pollen is only 15-25 um in diameter which would rule out this enormous grain. If I am wrong on the size please let me know.
I have to admit it does look like them.

Out in the forest on Sunday and found this. It's amazing how many plants were used for medical purposes in the past.

Almost run out of flowers but found this one in the forest while looking for mushrooms and interesting stones.

What a beautiful little plant! I like the hidden pollen-grains too.
Nicely-done.

More from our garden. This plant is on the black list for invasive species in Germany, maybe I should pull it out, only its so pretty (I think I probably have the wrong identification ;) )

First one of the year, from the garden of course. It took me four hours to remember how I combined the images and still haven't remembered the whole thing try again tomorrow with a different plant :-

A favorite among children at this time of year (me included). This growing in the cobbles in our garden is however the biggest I have ever seen at 153 cm.

Sorry no crossections as I didn't want to maul such a magnificent specimen. :(

As usual you can see the image in all it's glory by clicking on it. :D

Very nice - a superb image of the foxglove.
I like the presentation very much, with the example pollen-grain included.
Nicely-done!
