I haven't tried but I heard that nipping it off and putting a drop of clear on top of it before marvering helps to prevent the stamen to spread all over the place, sort of like with murini's, you need to cover those with clear too.Just push in the entire stamen stringer, nip it off and cover with a drop of clear ( only on top of the nipped off stamen stringer)
I could be completely wrong here ,but it sounds logical to me.
