Runaway seedling or new growth?

[mackarov]

I purchased this Bulbophyllum plant a few months ago and shortly there after noticed this small green growth near/under one of the pseudobulbs. I thought it to be a new growth or perhaps the early start of a flower spike but it is not growing at nearly the same rate as the rest of the plant which has produced 3 1"+ long new leads in a few weeks. I am starting to question if this might be a really small orchid just getting its way started semi-naturally. To give an estimate of its current size the white rod in the bottom left of the 2nd picture is 2.5# fishing thread. Thanks for any advice.
