Has anyone heard of a possible new species like callosum from Vietnam? Apparently it has much larger, but similar looking blooms. I was just offered flasks for about $30 each here in Bangkok, so I am wondering if I should get it.

Will do.
Just got some more info. Apparently it is vinicolour.

Ask Baodai.
Thanks Baodai
I tried to send a message about this last night, but my internet is not good at the moment.
I have asked the seller for a photo of the flower. Thanks for this information as it is helpful. In your opinion then, it is just another callosum and not a new species then?
Brett
It is vinicolor + larger flower, leave much thicker and stronger plant, It is come from warmer area

very unlikely ... more likely is a geographical variant .... tetraploidy occurs ins single plants ... populations ????? But if someone wants to know ... just count the chromosomeslarger, thicker, stronger... A tetraploid population?

Some individual plants are ... but not "species". A "species" is a population of individuals. A "species" is never a single plant.Ah, that's one, two, three, five, DOH!
Sorry, but aren't some species naturally tetraploid? The name Rhododendron calendulaceum comes to mind. While polypoloidy does occur in many species of deciduous azalea, this species is strictly 4N, or perhaps I've got my lines all crossed up. Wouldn't be the first time!
If that is so .. explain the biology to me ... tetraploidy is a mutation, and that occurs in single individuals. To get a population you would have to propagate that tetraploid without interference from other non-tetraploid individuals. And that is only possible in a lab (if at all) .... Ths never happens in the wild.Tetraploid populations are well documented in many plant species. Tetraploidy has also played a significant role in plant evolution and speciation, and somewhere between a single tetraploid plant and a new species arising from it there must be a population. A simple internet search on 'tetraploid population' or 'tetraploid species' should pull up a least a few examples.
But then, as you say, you have a different species ... and if that happened in the wild ... then the original tetraploid "specimen" must have become immediately isolated and must have propagated vegetatively only .... ????I was about to say the same thing....Isn't Rhododendron calendulaceum essentially a tetraploid species derived from R. cumberlandense (bakeri)?
No one ever claimed that polyploidy does not occur ... it occur everywhere (even in humans) ... but in INDIVIDUALS, not in entire populations.Ah, that's one, two, three, five, DOH!
