Ken, I believe that is a pup. One of the four I see when hiking looks to have a pup also, at least it has another smaller plant right under it.
I did find this:

If I'm understanding it correctlly the T. utriculata can produce offshoots, but mostly spreads by seeds. So I guess you got a pup producer
Anyhow it is quite an outstanding Tillandsia, and you have a very nice specimen. I would love to see photos of it as it continues to grow and flower.
I'm wondering if this plant I found on the ground right after the hurricane this past October may be a T. utriculata now? I found it right around the same area as all these plants, it is about five inches wide.
