Both U. quelchii clones are currently flowering together for the 1st time. Once I got pics of each & started to look at them, I was surprised at how different they are - both in color & structure. I had not noticed this before. Since differences in lighting / white balance can easily change the perception of color, I also spent time attempting to get one pic with flowers from both clones in it so there was little doubt as to the differences. Since the flowers faced away from the front of the tank (naturally), this was almost impossible... Structurally, the Ilu tepui clone reminds me of of U. campbelliana, for color (for which I am an extremely poor judge), the no-location clone appears closer to U. campbelliana... BCP clone - no location Ilu tepui Both (this is a different stalk of the no-location clone from the one pictured above)
