Hi! Out of curiosity, I was wondering how you could tell an epipremnum pinnatum v. aurea from simply a golden pothos. I know they're very similar, especially in juvenile form, but I was wondering if there was anything inherent about each plant that makes it unique other than the pinnate-ness of the leaves. I tried comparing sheaths, but maybe something like that becomes more apparent as it matures? Thanks!

and I say other than the pinnate shape because I see some golden pothos with more pinnate leaves, and some e. pinnatum with more heart shaped leaves! So I was wondering if there was another factor.

There is an excellent article on this on Aroid.org
E. pinnatum 'Aureum' is unknown in the wild and has no resolved provenance. It is supposed to have come from the solomon Islands but there is no record of it ever being wild collected. It is thought to have possibly been a cultivated selection of E. pinnatum

The article lists these differences between E. pinnatum 'Aureum' and E. area, which is misnamed as 'Golden Pothos':

Pinnatum leaf shape is ovate to ovate/lanceolate and thicker
aureum leaf shape is lanceolate to elliptic

The characteristic netted sheath is present in pinnatum, absent in aureum

Leaf lamina pinholes are present in pinnatum and smaller fewer in aureum and almost never perforate

Pinnatum leaves are thicker than aureum

Aureum produces a massive amount of foraging flagellate roots and many many offshoots (which is why its so invasive when it gets loose somewhere like South Florida), pinnatum is sparser and produces much less roots and offshoots

Sorry for the late reply! I had a crazy week with school. But yeah thank you! I actually read that article just prior to posting. Super interesting. I was staring at a juvenile e. pinnatum aurea next to an e. aurea's leaf that was slightly more pinnate than the rest and just could not see the differences! But maybe when it's a little older I'll try and post an update with any differences that I find! Thanks for the reply Gina!!
