John, I've never seen my E. aureum bloom. I am hoping it might bloom this season since it is approaching the 15 foot level. My leaves look like your's but the largest are even more elongated. I'll check more of the scientific sites and see if I can find a photo or description of the inflorescence.
You can see the adult leaf of Epipremnum pinnatum with an inflorescence here:

It isn't uncommon to find the two species confused in some scientific info but in may last conversation with Pete (several years ago) he explained the are truly different.
