TY for the help, Lin. I still don't understand it because I've never seen this other vine, unless you're saying micans IS the other vine? Micans leaves are reddish/burgundy on the back, a noticeably different plant from that pic of mine you included above, regular, smooth, heart-leaf vine (with leaves that are green on the back.) I have 3, including these two and 'Brazil.'
So, reading through this article again...

Micans is apparently a sport, definitely not a cultivar if it's been around longer than the hybridization of tropicals for commercial use, regardless of the fact that I've only seen it recently, in BBS's via EA.
Micans just now:
All other pics of heart-leaf vine besides 'Brazil' that I've uploaded are of the exact same (non 'Micans' and non 'Brazil') plant, that I've had for so long. So, are you saying the micans pics should be in this entry?:
Velvet Leaf Philodendron (Philodendron hederaceum)
And the other, non-Brazil plant goes here?:
Heart Leaf Philodendron (Philodendron hederaceum var. oxycardium)
