My father has had this cymbidium for some time. I have narrowed it down to either cymbidium pendulum, Cymbidium aloifolium, or Cymbidium finlaysonianum. Flowers in spring. And has an hour-glass shape on the inside of the lip. I'm no cymbidium expert but is the hour-glass shape a diagnostic feature of cymbidium aloifolium? i was reading on orchidspecies.com under aloifolium that aloifolium has an hour-glass shape inside the lip. Here are some pics. thanks
