It sounds like those are male flowers. My Dwarf Brazilian had hands of 7, 7, 7, 8, 8 and then the next hand had 3 more and about 5 male flowers (I think, though they have not dropped off). The subsequent hands have been male flowers which have dropped off.
Can't you tell the difference between boys and girls???
There's got to be an explanation of this online, I'll look in a bit.
