It seems to be Peperomia miqueliana (see TRGP at www.peperomia.net/repertory.asp for a picture of a flowering plant)

P.angulata is a synonym of P. quadrangularis (with rather round, opposite leaves). The pictured plant plant is usually called P. puteolata, although it does not match completely the type specimen of that name.

This is P. prostrata.
P. rotundifolia has bright green leaves without the typical variegation pattern of P. prostrata.

P. fosteri is one of the 'herbarium names' of W. Trelease. Its accepted name is P. dahlstedtii.

The photo shows indeed P. quadrangularis (with opposite leaves).

I think this is what I have as angulata which is now accepted as qudrangularis. It does not have the whorls of leaves that fosteri has. P fosteri also seems to be a species name that is doubtful.

I have this one labeled as puteolata. I have seen it referenced as quadrangularis but I'm not sold on the name. I have never seen angulata associated with this plant but you never know.

Looks like P trinervula rotundata but I have this plant and it's growth habit varies alot.

Not sure but would like a bit.

Looks like Peperomia fosteri

I believe Peperomia orba
