It is an UNKNOWN N. maxima hybrid. Gublers doesn't even know what it is. Could it be N. Mixta ... MAYBE It could also be any one of a dozen other hybrids (maybe a slight exaggeration but not by much). The point is it is unknown. Putting a name on it would be improper. Only in clear cases would I ever recommend a name for an unknow plant. Your best bet is to label it 'N. maxima hybrid'
