The very large flowered ones are 4N meaning they have been treated with to achieve the "double" about of chromosomes. The smaller flowered ones are "regular" 2N that Mother Nature intended. I have both types and I am sort of inclined to like the 2N better.
Good luck!

Well, yes and no. While most 4N clones are the result of deliberate chemical treatment (of seed protocorns or meristems), there are exceptions:
A. There are the occasional 4N mutations found in nature. One such example is Paphiopedilum insigne, var. 'Harefield Hall'. I have another Paph species, which I suspect is 4N, but it is seed propagated, so it might be the result of chemical treatment.
B. On occasion the basic meristem process leads to random 4N mutations. One such example is C. Caudebec 'Linwood' AM/AOS. In a batch of C. Caudebec 'Carmela' HCC/AOS, about 10% of the plants turned out to be 4Ns. From these Waldor Orchids selected the 'Linwood' clone, which is now readily available as a meristem.
C. When someone seed propagates two 4N clones, whether they were chemically induced or not, there is an argument for considering the seedlings natural 4Ns.
Whether 4N is preferable to 2N is a matter of personal perspective. I have both of the Caudebec clones mentioned above, and have bloomed 'Carmela' with as many as 14 flowers on the spike (it can have more). 'Linwood' is much bigger and fuller, but according to Waldor it never sets more than 10-11 flowers to the spike, and it is a slower grower.
