In the thread linked, Jon was saying that there are several variants of the Mission fig, different flavors and slight variations.
The red/pink stems seems to be a common trait of Black Mission/Vista varieties from what I've seen.
The three leaves I posted in the linked thread seem to be common amongst the ones I've seen, with slight variations, longer fingers and so forth.
Does the flavor of this tree you have resemble any other figs?
Thanks for sharing, btw.
