Hi Vivienne,
Capitain nomenclature to the rescue! Here to alieve your puzzlement over the name of your plant!
Onc. Mendenhall 'Hildos' and Psychopsis Mendenhall 'Hildos' are the exact same plant. Back in the 70's & 80's four Oncidium species were split off and renamed Psychopsis. The names became generally accepted by the scientific community and most importantly for our purposes were accpeted by the RHS for the registration of hybrids. It's certainly possible that there were a few tags out there that were never updated to say Psychopsis Mendenhall 'Hildos' and it sounds like that was the case with your plant.
From you second post, it sounds like someone may have thought there was
both an Oncidium
and a Psychopsis Mendenhall and that they were different plants. This is not the case. The RHS database contains only the registration for Psychopsis Mendenhall; no registration for Oncidium Mendenhall.
Once the plant gets back on its feet and starts blooming, don't cut the spikes off because they continue to re-bloom sequentially for years and years. A member of my orchid society back in the US had one of these with about 7 spikes on it. It was in nearly every show we exhibited at and always had 3-5 flowers on it.
Cheers!
