Can one shoot tip (in a plant) have more than one apical meristem?

    Does a plant stem always have just one apical meristem at any given time? If I think I see multiple buds at a single shoot tip (multiple "apical buds"?), what am I looking at? Is it:
    1. multiple ("codominant") apical meristems, or
    2. the buds compete for dominance until one of them ends up being the apical meristem, or
    3. one of the buds is the apical meristem & the others are axillary buds pressed up really close to it?
    Thanks!

    Understanding the origins of multiple buds at a single shoot tip quickly dives into growth and development at the molecular level ( Organogenesis at the Shoot Apical Meristem ).

    In the scenario above, if each of the buds are going to develop into a branch, then they all have their own SAM (as each shoot requires one).
