The anthers don't look quite like I expected they "should" !

Unfortunately I had to drop biology at 14.. :(

I think they have completely emptied ..
but the grains are definitely pollens!

What bothers me is that they seem to be coming out of the green container in the middle of "Big part off the flower".

Nic and ChrisR, thanks for the comments/pointers...

A bit late with my reply, well old to new things you know...
When 'dissecting' the flower, I found out that it are indeed pollen, coming from hidden filamentless stamen.....
Awaiting new flowers to come on this patch off violas for maybe a bit higher magnification...

The 'green container' is the stigma, so the pollen are going 'in' instead...

an interesting link I found during my search on the net:

Happy New Year to ALL !!
Always looking at the bright side of life,

Thanks Rude and Chris for the very interesting remarks and articles. Looking forward to new Viola flowers to photograph (and better understand) them, I wish you a happy new year!

It looks like you're right, Rudi - see picture 10B
in this paper. (I haven't read it all, my eyes tend to glaze over.. :smt101 but the solitary bee pollination behaviour is descibed from just above the page number 635. )
http://hortsci.ashspublications.org/con ... 3.full.pdf
which shows how intimate contact with bees (9C) is efficient. Clever plant!

I read that violas are self-pollinating (cleistagamous) late in the season, but that happens in capsules under low leaves - not in a flower. Something else to look for!

I came across a Tricyrtis toad lily today which has photogenic "bits" : http://www.microscopy-uk.org.uk/mag/ind ... dlily.html
A late-season flower. Some are elaborate and eg "Taipei silk" are very flashy.

Thanks for the link Chris. I have not yet seen those 'capsules under low leaves'. Don't know iff this is variety depended, but I will keep looking for them....

Funny you mention Tricyrtis....I have a 'normal' macro printed large in my office, taken back in 2011 or so,...and back in december I 'accidently' stumbled on my 'old' Tricyrtis folder....Definitvely an interesting subject, already on my 'to do' list for 2019.... :wink:

I am not yet finished with this one....
I removed a few bits and pieces (well some petals actually..) to reveal a bit from the hidden parts....

A closer look from the above, my first try with the Mitty 20x. I guess the big halooing is caused by the stack not being deep enough. Please correct me iff I am wrong..
The stigma 'moved' a bit during stacking, nevertheless Zerene did a good job in stacking..IMHO.

Another flower..Looks like a 'grumpy old man'... :D :D

All C&C most welcomed.
