Identification: Need indoor plant ID

Hello,

I received this plant from a friend who moved out of the country to Europe. I care a lot about this plant...but I do not know what it is, and I do not know how to care for it (dirt, water, light, food, etc...). Please help!

 

Pothos or Devil's Ivy. Janet

 

I'm not so sure that this is a pothos. It does bear a resemblance but i wonder if its a extremely leggy diffienbachia. It might not be but something about it says to me that it might not be a pothos/devil's ivy.
Anyone else have input?

Is this plant kept in a very low light area where it might have to stretch towards a window?

 

Possibly a verrrrrrry legggggggy deif, if so I would give it a haircut just above one of the leafless nodes. Janet

 

Could it be some sad, struggling poinsettia that someone has kept alive WAY past it's prime?

 

it does look like a very leggy dumbcane .. it really needs alot more sun ...
