I've been raising this nep since it was a rootless bud from Wistuba. It was sold to me as a N. macrophylla but recent reports state that a lot of the so called macros from Wistuba turned out to be N x Trusmadiensis. I think it's reached a point where it maybe possible to make a positive ID. Here are photos of the plant:
I would welcome any thoughts on what you think the plant is and why you think it is either a macrophylla or xTrusmadiensis.
