so every N. ventricosa x x trusmadiensis can be called N. "Sabre".
i know ep as 2 clones A and B (if i am not mistaken B got wide peristome),also he lists now clone C ,and there are lots of SG plants of this hybrid.
so every single one of this clones can be called N. "Sabre" ?
Yes, and every other plant on the planet can also be called N. "Sabre", or whatever else you wish. But officially, N. "Sabre" is neither a registered grex name, nor a valid cultivar name. It is simply a pet name, or nickname someone has decided to attach to the hybrid, only guessed to be (N. ventricosa x x trusmadiensis). See CP Photo Finder for
N. "Sabre". Since the parentage is uncertain, this fact disqualifies it to be registered as a grex. Every individual plant, produced from seed, is potentially a unique clone. Clone, in this sense, simply means "genetically unique individual". So there may be as many unique clones as there are seeds that grew into plants.
Unique plants can be registered as cultivars (for free), regardless of their parentage. Once a unique plant is registered as a cultivar, you can compare your plant to the published description and photographic standard, so you can be more certain that you are growing the plant you wish to grow.
Of course, any plant can look lousy (if it has lousy growing conditions), but under suitable growing conditions, a registered cultivar would have a much greater chance of appearing like its published description and standard photograph than any other random clone.
