Now let's look at Nestor versus Little Sweetscent!
Nestor was registered as a hybrid of Dendrobium parishii X Dendrobium superbum. But superbum is now properly anosmum. The registration date was 1892!!
Dendrobium Little Sweetscent was registered in 2000. It is a hybrid of Dendrobium parishii X Dendrobium anosmum. But, anosmum as we have previously mentioned, is newer synonym for superbum. So here we go, Nestor and Little Sweetscent are synonym hybrid names!
Yes you read that correctly, synonym hybrid names. So which takes precendence??? "Nestor" because it was published in 1892, Little Sweetscent 2000.
I am going to lie down now, my head hurts.
