Could this be Paph. insigne x Paph. esquirolei? We just had a Paphiopedilum hirsutissimum var. esquirolei come on the judging table last month at the Great Lakes Center.
We did not award it but the flower was kind of a green, golden mustardy kind of color and the petals, dorsal margins, were ribbon like or undulated. That unknown Paph has the same undulation on the same margin.
It was definitely greenish, not bronze.
