Oooh! Sorry, I can't see what you see well enough in that pic to have an opinion about it, but unless I'm mistaken (and somebody please school me if so, only ever seen 1 bloom on one in person) if it's forming 'below' a leaf, it can only be a bud? I don't think they branch out with new leaf tips, or make more than 1 leaf at a time (per growth tip,) but am a relatively new observer to this kind of Philo, welcoming any info folks might have to share.
If correct about visual interpretation, it looks like another bud is forming on my plant. Original bud is the large thing to the left, little nubbin to the right is what I think is another bud. Both bud suspects are coming from the petiole of an open leaf, right where it comes from the main stem.
From a little farther back - new leaf is very tall on the left (1), to its' right is the first 'bud' (2,) then the one I noticed last night to the right of that (arrow pointing to.)
(Duh, edited because I attached the version of the pic without numbers, arrow...)
