Joe,
I know that the breeder-propagator of this hybrid names the plants after the female. It's the same outfit that sells Miranda and Gentle. If you've ever seen their wholesale pricelist, they call these to plants : N. maxima Miranda and N. maxima Gentle. Obviously, they are not maximas any more than the Nep in question is not tobaica. Why would they call this plant tobaica if the podbearer was not tobaica-or possibly a mislabled tobaica hybrid? The pollen donor could have been an emmarene, ventricosa, some other ventricosa hybrid. They will not divulge the parentage on the basis of proprietary information.
The point I have been trying to make is not to call it 'emmarene' because no one can prove that it is (ventricosa x khasiana). True emmarene was made by a couple of guys in Miami-allow me to name drop: Ron Pratt and Craig Johnson, using simultaneously blooming ventricosa and khasiana in their private collections. They dispersed the seed to a number of growers. The plants among the seedlings that were strongly reddish in color were collectively called 'Savanah Rose'. The name emmarene is not really recognised by the IRA because it is a grex name. Anyone remaking the cross could call it emmarene if they wanted to, but could call it something else as well. The ICPS would say its a bogus name anyway.
