Cymbidium (Bicolor) sp. from Sikkim (Apr-09)
Depending on perception this could be either Cymbidium bicolor or Cymbidium aloifolium.
Many people say the one with dark band on flower is aloifolium based on the original description in Hortus Malabaricus where as other is Cymbidium bicolor without bands.

This may not be hybrid. Possible Cymbidium aloifolium or Cymbidium bicolor, depending on what you believe.

Yes both aloifolium and bicolor are different species. The one without band was long known to be aloifolium and bicolor as the one with bands. But then someone pointed out that aloifolium name was derived from the description in Hortus Malabaricus where the flowers have band and hence the nomenclature should be other way around.
Some people accept, where as others don't
