It refers to chromosome count, Kelly. You may remember from biology class back in your high school days that typically organisms have two sets of chromosomes -- thus they are 2N. Plants are unusual in comparison to animals in that they can have an extra set of chromosomes and still be okay. For an animal this would be lethal. Oddly enough, plants that have two extra sets of chromosomes (so they have a total of 4 sets), hence they are referred to as 4N. Often these plants display greater hybrid vigor and may produce more flowers and larger ones at that. (And you probably never thought you'd have any reason to know that science stuff they taught you in "real life", did you? Scary isn't it? )
Love the name of this dendrobium and the color in the blooms, Kelly. Nice!
