The plant is also known as Scindapsus outside of the US (botanical names Scindapsus Aureus or Epipremnum Aureum). The common name used in plant centres is "Devil's Ivy".
Any garden centre should be able to order you one in as that is what i did. Also check out http://www.dartfrog.co.uk/ as he does other couple of types of pathos.
you said you could only find hanging pothos... well, it's the same plant but they just added the word 'hanging' because it was (most likely) in one of those 'hanging' pots with a hook on it.
if it looked anything like the hanging pothos on this link, then you did find the right plant, you just didn't buy it lol ^^
