Indeed Rick, it was H. Koopowitz who raised it up to species rank, whereas KEW Science and others see this name a synonym to Paphiopedilum callosum var. callosum .If memory serves me, I think it was Harold Koopowitz who raised this paph to species rank. Prior to that it was considered a callosum vinicolored. The problem still exists today in that there were only three maybe four clones ever discovered. People had/have a hard time excepting viniferum as a species with so few ever found but anything is possible.
Here is an article describing the history and showing 3 clones....
There is a major difference between the source Rick and Paphfreak shared.
The first article says it was callosum 'Sparkling Burgundy' FCC that was used as a building block of modern vinicolor hybrids whereas the second article says it was callosum 'JAC' if I read it right without being confused?
Viniferum is now considered a separate species but there's no known population but just a single plant originally? hmmm
The whole thing sounds very strange.
@Paph Paradise Since you jumped in…. ;-).'Sparkling Burgundy' is the source of the vinicolor line...this is straight from our late friend Norito. 'JAC' is recessive for vinicolor, but did breed for wider petals with spots. Again, this comes from Norito.
Perfect. I’ll do the same ;-)They are just sitting next to our Paph wardii. That would put them closer to the heater (not sure if that matters, but it's where they landed). They are in the shadiest part of the nursery as well. Other than that they are treated like everything else. Watered and fertilized once per week with our crunchy, high calcium water.
Might be so, but I can't believe, that the flower in this thread was anything close to what Koopowitz raised to species rank... everything screams hybrid IMHO!
