Help for image of pollen of artichoke
 

Hello,
I need an microscopic image of pollen of artichoke ("Cynara cardunculus
scolymus" would be optimal). The pollen, not the plant.
I thank all those people who will help me.
I need the pollen image and dimension in micron.
The best would be an internet url or an email with the image in
attachment.
Excuse for my terrible english.
Thank you in advance.
Max
