I have a problem with this pollen type. I'm analyzing a sample of pollen from wild bee (Lasioglossum sp.) body in Israel. Other pollen type is Senecio sp. Pollen approximate size is 20 μm. Any help is welcome- even for family level. Thank you!
Hi. You can get help from the following links. In my opinion, your pollen grain sample is similar to the pollen grains of Asteraceae. Maybe it's not bad to start your search from this family
Thank you very much for the links Massoumeh Farasat . I will look into it. One of the pollen type is belong Asteraceae (Senecio sp.), but the other, I'm not sure.
