Cyrtochilum meirax?
 

Is this Cyrtochilum meirax? or...? Growing naturally in the woods behind my house.

It doesn't look like it. Look at the shape of the callus on the lip. It does not have the same number of horns coming out of it.

It does look like a Cyrtochilum though.

Maybe Cyrtochilum midas. Not sure.

Thank you Philip that looks like a good call. Most references refer to C. midas as being from Ecuador but I found one from Valle Del Cauca, Colombia where I photographed mine.
