cymbidium can tolerate a wide range of temps from 29 to 100 fahrenheit (as long as appropriate air movement, humidity, etc are given at the extremes). For a cymbidium to flower, there has to be at least a 10 degree difference in day / night temp (with night-time low at 50 - 55). If temps are too warm for too long, flowering may not occur.
We're in NH and follow advice of cymbidium society of america cymbidium.org - plants are moved outdoors to a sunny location in mid-late April and stay there until Halloween, resulting in generally good to excellent spike inititiation and flowers.
Sorry can't help with id, but that is a lovely flower that you have there.
BTW, I just divided a giant NO ID cymbidium (into 18 3-5 growth divisions). At the center of the root mass, there was a tag with the plant's proper name - Cymbidium Sheretta.
