Schefflera lovers ... I need your help.

First off, I should start with saying that nothing is wrong with my schefflera. There would have been a few exclamation points and a much more frantic title to my post if anything were to be going amiss with my beloved schefflera "?".  You see that is the problem.  I have been googling like mental all the possibilities of what my treasure of a schefflera is.

The tag reads "Yuan Shan hardy Schefflera" ... but it certainly doesn't look like other Taiwaniana that I have seen.

Recently my friend Loree from danger garden posted about her new Schefflera delavayi  and I thought hmm... the leaves on hers look more like that of mine.  But upon further inspection, no I don't think we have a match... although closer in appearance to delavayi than taiwaniana...

What got me thinking was the arrangement of the leaves.  I notice most of mine have five leaves in an almost star like shape.

But to make things more interesting, just under half of them have 8.  Seeing that I'm not a schefflera expert yet, I am left baffled.

Another piece of the puzzle are the slight red stems just below each leaf.  At least this part is keeping with what I have seen of 'Yuan Shan'

And then there's the blooms....

Still not quite mature so this might not help.  But what about the fact that it's happening in July? Normal?

the tag. Is it possible that this is just an odd variation of the common Schefflera Taiwaniana 'Yuan Shan?'

I don't want to be too suggestive as to sway your opinions in any one direction, but my thoughts have been leaning in the direction of Schefflera Hoi. Could it be Hoi in disguise as 'Yuan Shan?' The mystery continues. What do you think!?!
