Danita,
Thank you so much for your post, as soon as you mentioned the size of the Butterfly Bush seeds I realized I had posted wrong. I meant Butterfly Weed, as you can see in the see in the second picture they are not all that small. I used them to illustrate the tissue under the seed because the Salvia seed were so small I was afraid they would not even show in the picture. I did remove the little fuzzy stuff. Don't think that really matters. I do have a Butterfly bush, but I normally just take cuttings from it.
