Hi Eric,
Thanks for your input.
What Stewart is trying to say is that when we buy H. nutans, we invariably get H. glabra x nutans hybrid. This is a natural occurring hybrid. And when they cross back with the parents they are hard to distinguish. It is like buying N. alata and ending up with N x Venrata!
I have studied a few photos of heterodoxa, nutans and heterodoxa x nutans (
http://www.humboldt.edu/~rrz7001/Heliamphora.html). If you look at heterodoxa x nutans hybrid you will see that the wing occur very high up, close to the opening (
http://www.fotop.net/averyorchids/He...nutans?r=fotop) whereas, nutans and glabra x nutans wings appear close to the ventricose.
In fact, if you compare our plants with photos of H. nutans, you will think they are H. nutans. One typical H. nutans photo (
